Review for gene: L3MBTL1 was set to RED
Added comment: Germline variation in this imprinted gene is not currently associated with disease.

Somatic deletions of 20q are associated with chronic myeloid malignancies. Aziz et al showed that a single heterozygous 20q deletion consistently resulted in the complete loss of expression of the imprinted genes L3MBTL1 and SGK2, indicative of a pathogenetic role for loss of the active paternally inherited locus. Concomitant loss of both L3MBTL1 and SGK2 dysregulated erythropoiesis and megakaryopoiesis.

Phenotypes for gene: KCNQ1OT1 were set to Beckwith-Wiedemann syndrome OMIM:130650; Russell-Silver Syndrome
Review for gene: KCNQ1OT1 was set to AMBER
Added comment: Limited evidence that isolated intragenic variation in KCNQ1OT1 is definitively associated with a phenotype.

KCNQ1OT1 encodes the regulatory antisense non-coding RNA KCNQ1OT1 (KCNQ1 overlapping) and is located within the KCNQ1OT1:TSS DMR (imprinting control region 2; IC2) at 11p15.5. IC2 is located within KCNQ1 intron 10. KCNQ1OT1 is maternally imprinted and paternally expressed. On the paternal chromosome, KCNQ1OT1 is transcribed and represses in cis the flanking imprinted genes, including the growth inhibitor CDKN1C, which is normally transcribed from the maternal allele. In 50% of the BWS patients, loss of methylation (LOM) of IC2 leads to biallelic expression of KCNQ1OT1 and biallelic silencing of CDKN1C (PMID 30635621). Expression is increased in BWS due to IC2 epimutations or paternal UPD.

Single nucleotide variants within KCNQ1OT1 have not been definitively associated with human disease. A heterozygous maternally inherited non-coding variant was identified in an individual with isolated omphalocele. This variant was shown to alter the methylation pattern of the imprinted allele (PMID 29047350).

Eggerman et al (PMID 32447323) described a 132 base pair deletion within KCNQ1OT1 associated with growth retardation in the case of paternal but not maternal transmission. This intragenic deletion did not affect IC2 methylation.

Microdeletions of IC2 involving KCNQ1OT1 on the paternal allele have been identified in a small number of patients with Russell-Silver syndrome. Similarly, microdeletions of IC2 involving KCNQ1OT1 on the maternal allele have been identified in a small number of patients with BWS. These deletions also variably involve KCNQ1 or CDKN1C. LoF in CDKN1C is a known cause of BWS. There is some evidence to suggest that disruption of KCNQ1 prevents maternal methylation at IC2 (PMID 30778172).

Publications for gene: OOEP were set to 29574422
Phenotypes for gene: OOEP were set to Multi locus imprinting disturbance in offspring
Review for gene: OOEP was set to RED
Added comment: Single report of biallelic variants in this gene in a mother of a child with Multi locus imprinting disturbance (MLID) and a transient neonatal diabetes mellitus phenotype.

This gene encodes part of the subcortical maternal complex (SCMC). Other genes in this group act as 'maternal effect' genes and are associated with early embryonic arrest, recurrent hydatiform mole and MLID in offspring.

As is the case for other genes encoding components of the SCMC, the pathogenicity of variants can be difficult to establish as reproductive outcomes are not recorded in genomic databases and variants may be listed in population databases as they are not classed as pathogenic in males or women with no reproductive history.

Functional studies of genes encoding components of the SCMC are limited as their expression is restricted to the oocyte and early embryo.

Added comment: Moderate evidence for autosomal dominant short QT syndrome 1 by ClinGen /gene curation expert panel (PMID: 34557911). A single missense variant (absent gnomAD) identified in two SQTS families. In family 1, it segregated with SQTS (QTc<370ms) in 23 carriers, and 19 non-carriers had a QTc>370ms. In family 2, it segregated in 4 individuals. Experimental evidence from in vitro and zebrafish models suggests reduced membrane localization of the mutated protein leads to intracellular alkalinization and shortening of the cardiomyocyte action potential duration.
ClinGen expert panel was divided between strong (4 votes) and moderate (5 votes).

Review for gene: USP48 was set to GREEN
Added comment: PMID: 34059922 - Bassani et al 2021 - 3 cases reported with variants in USP48 and non syndromic hearing loss. They first analysed 4-generation Italian family with 6 individuals with hearing loss. The only rare variant segregating with the disease was a missense variant in USP48 (NM_032234.7:c.1216G > A, NP_115612.4:p.(Gly406Arg)). The variant is present in GnomAD v2.1.1 with a minor allele frequency (MAF) of 6.7 × 10−5 (17 allele out of 251 304 with no homozygotes). They also observed one hearing individual in the family who was heterozygous for the variant, suggesting incomplete penetrance.
In a Dutch family the found by exome sequencing a missense variant in USP48 (NM_032236.7:c.2215_2216delinsTT, NP_115612.4:p.(Thr739Leu)). The probands mother and uncle were also affected by no sequence data was available for analysis.
In a French family a proband is reported with right profound sensorineural hearing impairment (at 12 months), but normal left hearing (at 6 years old). The patient is heterozygote for a de novo splice variant in USP48 (NM_032236.7:c.3058 + 2 T > C, NP_115612.4:p.?;) which is not found in GnomAD and is predicted to result in a frameshift resulting in either NMD or a truncated protein.
In functional experiments they showed that the two missense variants found in the Italian and Dutch families, and a shortened protein as predicted for the variant found in the French variant, showed an impaired ability to cleave tetra-ubiquitin into tri-, di- and mono-ubiquitin. Using immunohistology, they show that the human USP48 protein is present in fetal inner ear specimens.
In addition zebrafish lacking usp48 showed a significant decrease of auditory response in acoustic startle response assays at 600 and 800 Hz wavelengths.

Review for gene: PLXNA1 was set to GREEN
Added comment: Dworschak et al. (2021) via WES reported 10 patients from 7 families with biallelic (n=7) or de novo (n=3) PLXNA1 variants. Shared phenotypic features include global developmental delay (9/10), brain anomalies (6/10), and eye anomalies (7/10). Seizures were predominantly reported in patients with monoallelic variants. Zebrafish studies showed an embryonic role of plxna1a in the development of the central nervous system and the eye. Biallelic variants in the extracellular Plexin-A1 domains lead to impaired dimerization or lack of receptor molecules, whereas monoallelic variants in the intracellular Plexin-A1 domains might impair downstream signaling through a dominant-negative effect.

Review for gene: UNC13B was set to RED
Added comment: No OMIM human disease association. Gene encodes a presynaptic protein Munc13-2 highly expressed in the brain (predominantly cerebral cortex).

Variant interpretation data in human epilepsy cohort somewhat conflicting and restricted to a single study. Conflicting data esp regarding MOI, and evidence for pathogenicity of several of the variants is limited.

Wang et al, Brain, 2021 - trio-based whole-exome sequencing identified UNC13B in 12 individuals affected by partial epilepsy and/or febrile seizures from 8 unrelated families. Identified:
x1 de novo nonsense variant, absent in gnomad, damaging in silicos
x1 de novo splice site, absent in gnomad, damaging in silicos
x1 splice site variant present in unaffected mother (low frequency in gnomad)
x2 compound het in one individual - more severe phenotype postulated (x1 variant present in contro cohortl, the other variant present in low frequency in gnomad)
x1 missense variant - in Han Chinese major depressive disorders study, not in gnomad
x1 missense variant - highly conserved residue, not in gnomad
x2 other missense variant - highly conserved residue, low frequency in gnomad
Latter 4 missense variants cosegregated with affected individuals in the families

In Drosophila, seizure rate and duration were increased by Unc13b knockdown compared to wild-type flies, but these effects were less pronounced than in sodium voltage-gated channel alpha subunit 1 (Scn1a) knockdown Drosophila

De novo UNC13B variants previously reported in bipolar disorder and autism spectrum disorder

Added comment: WES in 1 family with 3 siblings with clinical symptoms of PCD identified compound heterozygous loss-of-function variants in CFAP221, which segregated with disease. No functional studies. Nasal epithelial cells from 1 of the subjects demonstrated slightly reduced beat frequency, however, waveform analysis revealed that the CFAP221 defective cilia beat in an aberrant circular pattern. A candidate gene in cases where PCD is suspected but cilia structure and beat frequency appear normal.

Added comment: Reinstein et al. (2018) used WES in a large consanguineous Israeli Arab kindred consisting of 16 patients affected with the neurogenic type of arthrogryposis multiplex congenita. They identified a homozygous missense (V98E) mutation in ERGIC1 gene, which segregated with the disorder in the kindred, and was not found in the ExAC database or in 212 ethnically matched controls. Functional studies of the variant and studies of patient cells were not performed. ERGIC1 encodes a cycling membrane protein which has a possible role in transport between endoplasmic reticulum and Golgi.

Marconi et al (2021) used genome sequencing in a consanguineous family with 2 affected siblings presenting congenital arthrogryposis and some facial dysmorphism. They identified a homozygous 22.6 Kb deletion encompassing the promoter and first exon of ERGIC1. mRNA quantification showed the complete absence of ERGIC1 expression in the two affected siblings and a decrease in heterozygous parents.

Added comment: No individuals reported with GPX1 variants identified as the cause of Haemolytic anaemia due to glutathione peroxidase deficiency. Multiple papers report a number of cases of Haemolytic anaemia due to glutathione peroxidase deficiency, however there is no defined link or variant to GPX1 (PMID: 5766310. PMID: 1131421, PMID: 2492138, PMID: 476008)

Overall, lowered glutathione peroxidase activity has been observed in a number of individuals with haemolytic anaemia however the evidence for a cause-and-effect relationship between the enzyme deficiency and the presenting anaemia is not evident.

Added comment: 4 affected individuals and 2 unaffected controls from one Chinese PPPK family where disease locus was mapped at 8q24.13-8q24.21 by previous linkage analysis. Exome sequencing analysis identified a heterozygous variant in COL14A1 gene (c.4505C>T (p.Pro1502Leu)). The variant was shared by 4 affected individuals, but not 2 controls of the family. Sanger sequencing confirmed this variant in another four cases from this family. Variant was absent in the normal controls of this family as well as 676 unrelated normal controls and 781 patients with other disease. The missense substitution occurs at a highly conserved amino acid residue across multiple species.

Rare, likely loss-of-functions IFIH1 variants identified in eight independent probands with Very Early Onset Inflammatory Bowel Disease (VEOIBD) from a combined cohort of 42 children. IFIH1 variants were significantly enriched in children with VEOIBD as compared to controls (p=0.007).
In one case of neonatal-onset IBD, a homozygous truncating variant was identified. There were seven carriers of LoF variants identified (range of onset 6 months to 6 years of age). In three of these cases, a second hypomorphic missense variant was identified.
Luciferase reporter assays were employed to assess MDA5 activity. In some cases, the second missense variant was either proven to not affect protein function or was in cis with the LoF variant.
Complete and partial MDA5 deficiency is associated with VEOIBD with variable penetrance and expressivity, suggesting a role for impaired intestinal viral sensing in IBD pathogenesis.

158 affected individuals from 22 unrelated families with familial adult myoclonic epilepsy with a heterozygous 5-bp repeat expansion (ATTTC)n in intron 1. Affected individuals had variable expansion of an endogenous (ATTTT)n repeat in addition to the insertion of an abnormal (ATTTC)n repeat, similar molecular finding in other forms of FAME. RNA sequencing from patient derived fibroblasts shows no accumulation of the AUUUU or AUUUC repeat sequences and no effect on STARD7 gene expression, suggesting ATTTC expansions may cause FAME irrespective of the genomic locus involved.

Mendeliome v0.8861 IGF2 Zornitza Stark changed review comment from: RSS phenotype.; to: Silver-Russell syndrome-3 (SRS3) is characterized by intrauterine growth retardation with relative macrocephaly, followed by feeding difficulties and postnatal growth restriction. Dysmorphic facial features include triangular face, prominent forehead, and low-set ears. Other variable features include limb defects, genitourinary and cardiovascular anomalies, hearing impairment, and developmental delay. Disruption of any gene in the HMGA2-PLAG1-IGF2 pathway results in a decrease in IGF2 expression and produces an SRS phenotype similar to that of patients carrying 11p15.5 epigenetic defects.

Begemann et al. (2015) performed exome sequencing in 4 affected people with severe growth restriction in one family, and identified a heterozygous nonsense mutation in the IGF2 gene that segregated fully with the disorder. Affected individuals inherited the mutation from their healthy fathers, and it originated from the healthy paternal grandmother. Clinical features occurred only in those who inherited the variant allele through paternal transmission, consistent with maternal imprinting of IGF2.

Many other cases reported since with de novo mutations in IGF2 present on the paternal allele.

Mode of inheritance for gene: RNF220 was set to BIALLELIC, autosomal or pseudoautosomal

Review for gene: RNF220 was set to GREEN
Added comment: Sferra et al (2021 - PMID: 33964137) provide extensive evidence that biallelic RNF220 mutations cause a disorder characterized by hypomyelinating leukodystrophy, ataxia (9/9 - onset 1-5y), borderline intellectual functioning (3/9) / intellectual disability (5/9 - in most cases mild), sensorineural deafness (9/9) with complete hearing loss in the first decade of life, hepatopathy (9/9) with associated periportal fibrosis, and dilated cardiomyopathy (9/9) which was fatal.

Other neurologic manifestations apart from ataxia incl. hyperreflexia (8/8), spastic paraplegia (9/9), dysarthria (9/9), peripheral neuropathy (4/9), seizures in one case (1/9). Upon brain MRI there was thin corpus callosum (9/9) or cerebellar atrophy in some (2/9).

The authors identified homozygosity for 2 recurrent missense RNF220 variants in affected members belonging to these 5 broad consanguineous pedigrees (7 families), namely NM_018150.4:c.1094G>A / p.Arg365Gly in 4 Roma families in the context of a shared haplotype (/founder effect) as well as c.1088G>A / p.Arg363Gly in a large pedigree from southern Italy initially reported by Leuzzi et al (2000 - PMID: 10881263).

Extensive segregation analyses were carried out including several affected and unaffected members.

RNF220 encodes ring finger protein 220, which functions as an E3 ubiquitin ligase. Previous studies have shown among others a role in modulation of Sonic hedgehog/GLI signaling and cerebellar development

Evidence for the role of RNF220 included relevant expression, localization within the cell, interaction partners (lamin B1, 20S proteasome), similarities with other laminopathies in terms of phenotype, etc :
*RNF220 has a relevant expression pattern in CNS (based on qRT-PCR analyses in human brain, cerebellum, cerebral cortex / mRNA levels in human fetal CNS with higher expression in cerebellum, spinal cord and cortex / previous GTEx data / protein levels in mouse CNS)
*The protein displays nuclear localization based on iPSC cells differentiated to motor neurons (also supported by data from the Human Protein Atlas). Transfection of COS-1 cells demonstrated localization primarily to the nucleus (as also previously demonstrated in HEK293T cells) in vesicle like structures with ASF2/SF2 colocalization suggesting enrichment in nuclear speckles. There was also partial co-distribution with the 20S proteasome. R363Q and R365Q additionally coalesced in the cytoplasm forming protein aggregates/inclusions.
*Immunofluorescence studies in patient fibroblasts also confirmed abnormal increase of the protein in the cytoplasm and increased fluorescence with the 20S proteasome.
*Proteomic identification of RNF220-interacting proteins in transfected HEK293T cells demonstrated enrichment for all members of the lamin protein family (incl . lamin B1, AC, B2).
*RNAi-mediated downregulation of RNF222 in Drosophila suggested altered subcellular localization and accumulation of the fly orthologue for human lamin B1.
*Immunoprecipitation of lamin B1 from the nuclear matrix of cerebellar cells suggested significant interaction of endogenous lamin B1 with RNF220, while transfection studies in HEK293T cells for wt/mt suggested reduced binding to endogenous lamin B1 for RNF220 mt compared to wt (more prominent for R365Q). RNF220 mutants also reduced ubiquitination of nuclear lamin B1 compared to wt.
*Patient fibroblasts immunostained with different nuclear envelope markers displayed abnormal nuclear shapes with multiple invaginations and lobulations, findings also observed in laminopathies.

Added comment: Sakamoto et al (2021 - PMID: 34346499) provide some evidence that monoallelic ARF3 pathogenic variants may be associated with a NDD with brain abnormality.

Using trio exome sequencing, the authors identified 2 individuals with NDD harboring de novo ARF3 variants, namely: NM_001659.2:c.200A>T / p.Asp67Val and c.296G>T / p.Arg99Leu.

Individual 1 (with Asp67Val / age : 4y10m), appeared to be more severelely affected with prenatal onset progressive microcephaly, severe global DD, epilepsy. Upon MRI there was cerebellar and brainstem atrophy. Individual 2 (Arg99Leu / 14y) had severe DD and ID (IQ of 23), epilepsy and upon MRI cerebellar hypoplasia. This subject did not exhibit microcephaly. Common facial features incl. broad nose, full cheeks, small philtrum, strabismus, thin upper lips and abnormal jaw. There was no evidence of systemic involvement in both.

ARF3 encodes ADP-ribosylation factor 3. Adenosine diphosphate ribosylation factors (ARFs) are key proteins for regulation of cargo sorting at the Golgi network, with ARF3 mainly working at the trans-Golgi network. ARFs belong to the small GTP-binding protein (G protein) superfamily. ARF3 switches between an active GTP-bound form and an inactive GDP-bound form, regulated by guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs) respectively.

Members of the ARF superfamily regulate various aspects of membrane traffic, among others in neurons.

There are 5 homologs of ARF families, divided in 3 classes. ARF3 and ARF1 belong to class I. Monoallelic ARF1 mutations are associated with Periventricular nodular heterotopia 8 (MIM 618185).

In vivo, in vitro and in silico studies for the 2 variants suggest that both impair the Golgi transport system although each variant most likely exerts a different effect (gain-of-function for Arg99Leu vs loss-of-function/dominant-negative for Asp67Val).

This was also reflected in somewhat different phenotype of the subjects with the respective variants. Common features included severe DD, epilepsy and brain abnormalities although Asp67Val was associated with diffuse brain atrophy as well as congenital microcephaly and Arg99Leu with cerebellar hypoplasia.

Evidence to support the effect of each variant include:

Arg99Leu:
Had identical Golgi localization to that of wt
Had increased binding activity with GGA1, a protein recruited by the GTP-bound active form of ARF3 to the TGN membrane (supporting GoF)
In silico structural analysis suggested it may fail to stabilize the conformation of Asp26, resulting in impaired GTP hydrolysis (GoF).
In transgenic fruit flies, evaluation of the ARF3 variant toxicity using the rough eye phenotype this variant was associated with increased severity of the r-e phenotype similar to a previously studied GoF variant (Gln71Leu)

Asp67Val:
Did not show a Golgi-like pattern of localization (similar to Thr31Asn a previously studied dominant-negative variant)
Displayed decreased protein stability
In silico structural analysis suggested that Asp67Val may lead to compromised binding of GTP or GDP (suggestive of LoF)
In transgenic Drosophila eye-specific expression of Asp67Val (similar to Thr31Asn, a known dominant-negative variant) was lethal possibly due to high toxicity in very small amounts in tissues outside the eye.

There is no associated phenotype in OMIM, G2P or SysID.

Added comment: Altuame et al (2021 - PMID: 34327814) describe 3 individuals from 2 consanguineous Arab families with biallelic PLXNA2 variants.

The index patient from the 1st family presented with CHD (hypoplastic right ventricle, ASD), DD and moderate ID (IQ of 40), failure to thrive as well as some dysmorphic features (obtuse mandibular angle, mild overbite, synophrys with downslanting p-f, strabismus, etc). There were additional features (eg. postaxial polydactyly) which were found in other affected and unaffected family members.

Exome sequencing with autozygome analysis revealed homozygosity for a PLXNA2 stopgain variant (NM_025179:c.3603C>A / p.(Cys1201*)).

Sanger confirmation was carried out and segregation analyses confirmed carrier status of the unaffected parents and a sib as well as a brother homozygous for the same variant. Clinical evaluation of the latter, following this finding revealed borderline intellectual functioning, ADHD, failure to thrive. There was no mandibular anomaly or overbite and no clinical evidence of CHD (no echo performed).

The index patient from the 2nd consanguineous family was evaluated for ID (IQ of 63), with previous borderline motor development, ADHD and some dysmorphic features (obtuse mandibular angle and overbite). There was no clinical evidence of CHD (no echo performed).

Exome sequencing with autozygosity mapping revealed a homozygous missense PLXNA2 variant (c.3073G>A / p.(Asp1025Asn), present only once in gnomAD (htz), with rather non-concordant in silico predictions SIFT 0.22, PolyPhen 0.682 and CADD 23.5. The aa was however highly conserved.

Segregation analysis confirmed carrier state of the parents and 2 unaffected sibs, with a 3rd sib homozygous for the wt allele.

As the authors discuss:
*PLXNA2 belongs to the plexin family of genes, encoding transmbembrane proteins functioning as semaphorin receptors. It has predominant expression in neural tissue. The protein is thought to bind semaphorin-3A, -3C or -5 followed by plexin A2 dimerization, activation of its GTPase-activating protein domain, negative regulation of Rap1B GTPase and initiation of a signal transduction cascade mediating axonal repulsion/guidance, dendritic guidance, neuronal migration.
*Murine Plxna2 knockout models display structural brain defects. In addition they display congenital heart defects incl. persistent truncus arteriosus and interrupted aortic arch.
*Rare CNVs in adult humans with tetralogy of Fallot have suggested a potential role of PLXNA2 in cardiac development and CHD.
*Expression and the role of PLXNA2 in human chondrocytes as well as a GWAS in 240 japanese patients with mandibular prognathism where PLXNA2 was suggested as a susceptibility locus.

Overall, the authors recognize some common features (as for cognitive functioning, some dysmorphic features incl. obtuse mandibular angle and overbite in 2 unrelated subjects, failure to thrive 3/3) and provide plausible explanations for the variability / discordance of others eg:
- Cyanotic heart disease explaining discordance in cognitive outcome among sibs
- Incomplete penetrance for CHD (and/or ID or mandibular anomaly) as for few AR disorders and/or
- Additional pathogenic variants possibly explaining the CHD in the first subject.

There is no associated phenotype in OMIM or G2P. SysID includes PLXNA2 among the candidate ID genes.

Review for gene: VPS50 was set to AMBER
Added comment: Schneeberger et al (2021 - PMID: 34037727) describe the phenotype of 2 unrelated individuals with biallelic VPS50 variants.

Common features included transient neonatal cholestasis, failure to thrive, severe DD with failure to achieve milestones (last examination at 2y and 2y2m respectively), postnatal microcephaly, seizures (onset at 6m and 25m) and irritability. There was corpus callosum hypoplasia on brain imaging.

Both individuals were homozygous for variants private to each family (no/not known consanguinity applying to each case). The first individual was homozygous for a splicing variant (NM_017667.4:c.1978-1G>T) and had a similarly unaffected sister deceased with no available DNA for testing. The other individual was homozygous for an in-frame deletion (c.1823_1825delCAA / p.(Thr608del)).

VPS50 encodes a critical component of the endosome-associated recycling protein (EARP) complex, which functions in recycling endocytic vesicles back to the plasma membrane [OMIM based on Schindler et al]. The complex contains VPS50, VPS51, VPS52, VPS53, the three latter also being components of GARP (Golgi-associated-retrograde protein) complex. GARP contains VPS54 instead of VPS50 and is required for trafficking of proteins to the trans-golgi network. Thus VPS50 (also named syndetin) and VPS54 function in the EARP and GARP complexes, to define directional movement of their endocytic vesicles [OMIM based on Schindler et al]. The VPS50 subunit is required for recycling of the transferrin receptor.

As discussed by Schneeberger et al (refs provided in text):
- VPS50 has a high expression in mouse and human brain as well as throughout mouse brain development.
- Mice deficient for Vps50 have not been reported. vps50 knockdown in zebrafish results in severe developmental defects of the body axis. Knockout mice for other proteins of the EARP/GARP complex (e.g. Vps52, 53 and 54) display embryonic lethality.

Studies performed by Schneeberger et al included:
- Transcript analysis for the 1st variant demonstrated skipping of ex21 (in patient derived fabriblasts) leading to an in frame deletion of 81 bp (r.1978_2058del) with predicted loss of 27 residues (p.Leu660_Leu686del).
- Similar VPS50 mRNA levels but significant reduction of protein levels (~5% and ~8% of controls) were observed in fibroblasts from patients 1 and 2. Additionally, significant reductions in the amounts of VPS52 and VPS53 protein levels were observed despite mRNA levels similar to controls. Overall, this suggested drastic reduction of functional EARP complex levels.
- Lysosomes appeared to have similar morphology, cellular distribution and likely unaffected function in patient fibroblasts.
- Transferrin receptor recycling was shown to be delayed in patient fibroblasts suggestive of compromise of endocytic-recycling function.

As the authors comment, the phenotype of both individuals with biallelic VPS50 variants overlaps with the corresponding phenotype reported in 15 subjects with biallelic VPS53 or VPS51 mutations notably, severe DD/ID, microcephaly and early onset epilepsy, CC anomalies. Overall, for this group, they propose the term "GARP and/or EARP deficiency disorders".

There is no VPS50-associated phenotype in OMIM or G2P. SysID includes VPS50 among the ID candidate genes.

Added comment: There is enough evidence to include this gene in the current panel with green rating.

Biallelic PIDD1 pathogenic variants have been reported in 26 individuals (11 families) with DD (all), variable degrees of ID (mild to severe), behavioral (eg. aggression/self-mutilation in several, ADHD) and/or psychiatric abnormalities (ASD, psychosis in 5 belonging to 3 families), well-controlled epilepsy is some (9 subjects from 6 families) and MRI abnormalities notably abnormal gyration pattern (pachygyria with predominant anterior gradient) as well as corpus callosum anomalies (commonly thinning) in several. Dysmorphic features have been reported in almost all, although there has been no specific feature suggested.

The first reports on the phenotype associated with biallelic PIDD1 mutations were made by Harripaul et al (2018 - PMID: 28397838) and Hu et al (2019 - PMID: 29302074) [both studies investigating large cohorts of individuals with ID from consanguineous families].

Sheikh et al (2021 - PMID: 33414379) provided details on the phenotype of 15 individuals from 5 families including those from the previous 2 reports and studied provided evidence on the role of PIDD1 and the effect of variants.

Zaki et al (2021 - PMID: 34163010) reported 11 additional individuals from 6 consanguineous families, summarize the features of all subjects published in the literature and review the neuroradiological features of the disorder.

PIDD1 encodes p53-induced death domain protein 1. The protein is part of the PIDDosome, a multiprotein complex also composed of the bipartite linker protein CRADD (also known as RAIDD) and the proform of caspase-2 and induces apoptosis in response to DNA damage.

There are 5 potential PIDD1 mRNA transcript variants with NM_145886.4 corresponding to the longest. Similar to the protein encoded by CRADD, PIDD1 contains a death domain (DD - aa 774-893). Constitutive post-translational processing gives PIDD1-N, PIDD1-C the latter further processed into PIDD1-CC (by auto-cleavage). Serine residues at pos. 446 and 588 are involved in this autoprocessing generating PIDD1-C (aa 446-910) and PIDD1-CC (aa 774-893). The latter is needed for caspase-2 activation.

Most (if not all) individuals belonged to consanguineous families of different origins and harbored pLoF or missense variants.

Variants reported so far include : c.2587C>T; p.Gln863* / c.1909C>T ; p.Arg637* / c.2443C>T / p.Arg815Trp / c.2275-1G>A which upon trap assay was shown to lead to skipping of ex15 with direct splicing form exon14 to the terminal exon 16 (resulting to p.Arg759Glyfs*1 with exlcusion of the entire DD) / c.2584C>T; p.Arg862Trp / c.1340G>A; p.Trp447* / c.2116_2120del; p.Val706His*, c.1564_1565del; p.Gly602fs*26

Evidence so far provided includes:
- Biallelic CRADD variants cause a NDD disorder and a highly similar gyration pattern.
- Confirmation of splicing effect (eg. for c.2275-1G>A premature stop in position 760) or poor expression (NM_145886.3:c.2587C>T; p.Gln863*). Arg815Trp did not affect autoprocessing or protein stability.
- Abnormal localization pattern, loss of interaction with CRADD and failure to activate caspase-2 (MDM2 cleavage assay) [p.Gln863* and Arg815Trp]
- Available expression data from GTEx (PIDD1 having broad expression in multiple tissues, but higher in brain cerebellum) as well as BrainSpan and PsychEncode studies suggesting high coexpression of PIDD1, CRADD and CASP2 in many regions in the developing human brain.
- Variants in other genes encoding proteins interacting with PIDD1 (MADD, FADD, DNAJ, etc) are associated with NDD.

Pidd-1 ko mice (ex3-15 removal) lack however CNS-related phenotypes. These show decreased anxiety but no motor anomalies. This has also been the case with Cradd-/- mice displaying no significant CNS phenotypes without lamination defects.

There is currently no associated phenotype in OMIM. PIDD1 is listed in the DD panel of G2P (PIDD1-related NDD / biallelic / loss of function / probable) . SysID includes PIDD1 among the current primary ID genes.

Added comment: Twenty individuals from seven families reported with de novo or transmitted haploinsufficient variants in SF3B2. Affected individuals had mandibular hypoplasia, microtia, facial and preauricular tags, epibulbar dermoids, lateral oral clefts in addition to skeletal and cardiac abnormalities.

Targeted morpholino knockdown of SF3B2 in Xenopus resulted in disruption of cranial neural crest precursor formation and subsequent craniofacial cartilage defects, supporting a link between spliceosome mutations and impaired neural crest development in congenital craniofacial disease.

The families were ascertained from a cohort and the authors suggest that haploinsufficient variants in SF3B2 are the most prevalent genetic cause of CFM, explaining ~3% of sporadic and ~25% of familial cases.

Added comment: 11 individuals reported, 9 that carried 8 different rare heterozygous missense variants in CLCN3, and 2 siblings that were homozygous for an NMD-predicted frameshift variant likely abolishing ClC-3 function. All missense variants were confirmed to be de novo in eight individuals for whom parental data was available.

The 11 individuals in the cohort share clinical features of variable severity. All 11 have GDD or ID and dysmorphic features, and a majority has mood or behavioural disorders and structural brain abnormalities:
- Structural brain abnormalities on MRI (9/11) included partial or full agenesis of the corpus callosum (6/9), disorganized cerebellar folia (4/9), delayed myelination (3/9), decreased white matter volume (3/9), pons hypoplasia (3/9), and dysmorphic dentate nuclei (3/9). Six of those with brain abnormalities also presented with seizures.
- Nine have abnormal vision, including strabismus in four and inability to fix or follow in the two with homozygous loss-of-function variants.
- Hypotonia ranging from mild to severe was reported in 7 of the 11 individuals.
- Six have mood or behavioural disorders, particularly anxiety (3/6).
- Consistent dysmorphic facial features included microcephaly, prominent forehead, hypertelorism, down-slanting palpebral fissures, full cheeks, and micrognathia.

The severity of disease in the two siblings with homozygous disruption of ClC-3 is consistent with the drastic phenotype seen in Clcn3 KO mice. The disease was more severe in two siblings carrying homozygous loss-of-function variants with the presence of GDD, absent speech, seizures, and salt and pepper fundal pigmentation in both individuals, with one deceased at 14 months of age. The siblings also had significant neuroanatomical findings including diffusely decreased white matter volume, thin corpora callosa, small hippocampi, and disorganized cerebellar folia. Supporting biallelic inheritance for LoF variants, disruption of mouse Clcn3 results in drastic neurodegeneration with loss of the hippocampus a few months after birth and early retinal degeneration. Clcn3−/− mice display severe neurodegeneration, whereas heterozygous Clcn3+/− mice appear normal.

Patch-clamp studies were used to investigate four of the missense variants. These suggested a gain of function in two variants with increased current in HEK cells, however they also showed reduced rectification of voltage and a loss of transient current, plus decreased current amplitude, glycosylation and surface expression when expressed in oocytes, and were suspected to interfere with channel gating and a negative feedback mechanism. These effects were also shown to vary depending on pH levels. The current of the remaining two variants did not differ from WT. For heterozygous missense variants, the disruption induced may be at least partially conferred to mutant/WT homodimers and mutant/ClC-4 heterodimers.

Both loss and gain of function in this gene resulted in the same phenotype.

Mendeliome v0.8583 PRDX3 Hazel Phillimore changed review comment from: Biallelic variants in 5 unrelated families with early onset (median 21 years , range 13-22 years) with ataxia with variable additional hyper- and hypokinetic movement disorders, and severe early-onset cerebellar atrophy (seen on MRI), and involvement of the brainstem, medullary olive and parietal cortex.
Evolution of the disease was gait ataxia leading to upper limb ataxia, then dysarthria and then dysphagia, all within a decade. For some of these patients, the phenotype included myoclonus, dystonia and / or tremor. Mild classical mitochondrial features were seen in one of the patients, namely ptosis and COX-negative fibres.
The variants were homozygous nonsense, homozygous frameshift, homozygous missense, and a compound heterozygote of a splice variant and missense, all leading to complete loss of the protein. Oxidative stress and mitochondrial dysfunction was indicated as the disease mechanism.
The families originated from Germany, France, India and two from eastern Turkey. The two families from Turkey were seemingly unrelated to each other but had the same homozygous missense.
Patient fibroblasts from each of the five probands showed lack of protein (via Western blot) and decreased glutathione peroxidase activity and decreased mitochondrial maximal respiratory capacity.
PRXD3 encodes peroxiredoxin 3, a mitochondrial antioxidant protein, that catalyses the reduction of hydrogen peroxide. It localises in the mitochondria, where most hydrogen peroxide is generated.
Functional studies: PRDX3 knockdown (induced by silencing RNA against PRDX3) in cerebellar medulloblastoma cells showed significantly decreased cell viability, increased hydrogen peroxide levels and increased susceptibility to apoptosis triggered by reactive oxygen species.
In addition, induced knockdown drosophila (in vivo animal model) had aberrant locomotor phenotypes and reduced lifespans, while immunolabelling of the brain showed increased cell death after exposure to oxidative stress.

For some of these patients, the phenotype included myoclonus, dystonia and / or tremor. Mild classical mitochondrial features were seen in one of the patients, namely ptosis and COX-negative fibres.
The variants were homozygous nonsense, homozygous frameshift, homozygous missense, and a compound heterozygote of a splice variant and missense, all leading to complete loss of the protein. Oxidative stress and mitochondrial dysfunction was indicated as the disease mechanism.
The families originated from Germany, France, India and two from eastern Turkey. The two families from Turkey were seemingly unrelated to each other but had the same homozygous missense.
Patient fibroblasts from each of the five probands showed lack of protein (via Western blot) and decreased glutathione peroxidase activity and decreased mitochondrial maximal respiratory capacity.
PRXD3 encodes peroxiredoxin 3, a mitochondrial antioxidant protein, that catalyses the reduction of hydrogen peroxide. It localises in the mitochondria, where most hydrogen peroxide is generated.
Functional studies: PRDX3 knockdown (induced by silencing RNA against PRDX3) in cerebellar medulloblastoma cells showed significantly decreased cell viability, increased hydrogen peroxide levels and increased susceptibility to apoptosis triggered by reactive oxygen species.
In addition, induced knockdown drosophila (in vivo animal model) had aberrant locomotor phenotypes and reduced lifespans, while immunolabelling of the brain showed increased cell death after exposure to oxidative stress.

Added comment: Semino et al (2021 - PMID: 34157790) provide clinical details on 3 unrelated individuals with de novo SYNCRIP variants and provide a review of 5 additional subjects previously identified within large cohorts in the literature and databases.

Features included DD, ID (7/7 for whom this information was available), ASD or autistic features (4/7). MRI abnormalities were observed in 3 (widening of CSF spaces, periventricular nodular heterotopia, prominent lat. ventricles). Epilepsy (myoclonic-astatic epilepsy / Doose syndrome) was reported for 2(/8) individuals.

The 3 patients here reported were identified following trio/singleton exome with Sanger confirmation of the variants and their de novo occurrence.

Variants are in almost all cases de novo (7/7 for whom this was known) and in 5/8 cases were pLoF, in 2/8 missense SNVs while a case from DECIPHER had a 77.92 kb whole gene deletion not involving other genes with unknown inheritance.

Overall the variants reported to date include [NM_006372.5]:
1 - c.858_859del p.(Gly287Leufs*5)
2 - c.854dupA p.(Asn285Lysfs*8)

SYNCRIP (also known as HNRNPQ) encodes synaptotagmin‐binding cytoplasmic RNA‐interacting protein. As the authors note, this RNA-binding protein is involved in multiple pathways associated with neuronal/muscular developmental disorders. Several references are provided for its involvement in regulation of RNA metabolism, among others sequence recognition, pre-mRNA splicing, translation, transport and degradation.

Mutations in other RNA-interacting proteins and hnRNP members (e.g. HNRNPU, HNRNPD) are associated with NDD.

The missense variant (p.Leu245Pro) is within RRM2 one of the 3 RNA recognition motif (RRM) domains of the protein. These 3 domains, corresponding to the central part of the protein (aa 150-400), are relatively intolerant to variation (based on in silico predictions and/or variation in gnomAD). Leu245 localizes within an RNA binding pocket and in silico modeling suggests alteration of the tertiary structure and RNA-binding capacity of RRM2.

There are no additional studies performed.

Overall haploinsufficiency appears to be the underlying disease mechanism based on the truncating variants and the gene deletion. [pLI in gnomAD : 1, %HI : 2.48%]

Animal models are not discussed.

There is no associated phenotype in OMIM. This gene is included in the DD panel of G2P (monoallelic LoF variants / SYNCRIP-related developmental disorder). SysID also lists SYNCRIP within the current primary ID genes.

Phenotypes for gene: CAMK4 were set to Intellectual disability; Autism; Behavioral abnormality; Abnormality of movement; Dystonia; Ataxia; Chorea; Myoclonus
Review for gene: CAMK4 was set to GREEN
Added comment: 3 publications by Zech et al (2018, 2020 - PMIDs : 30262571, 33098801, 33211350) provide clinical details on 3 individuals, each harboring a private de novo CAMK4 variant.

Overlapping features included DD, ID, behavoral issues, autism and abnormal hyperkinetic movements. Dystonia and chorea in all 3 appeared 3-20 years after initial symptoms.

CAMK4 encodes Calcium/Calmodulin-dependent protein kinase IV, an important mediator of calcium-mediated activity and dynamics, particularly in the brain. It is involved in neuronal transmission, synaptic plasticity, and neuronal gene expression required for brain development and neuronal homeostasis (summary by OMIM based on Zech et al, 2018).

The 473 aa enzyme has a protein kinase domain (aa 46-300) and a C-terminal autoregulatory domain (aa 305-341) the latter comprising an autoinhibitory domain (AID / aa 305-321) and a calmodulin-binding domain (CBD / aa 322-341) [NP_001735.1 / NM_001744.4 - also used below].

Variants in all 3 subjects were identified following trio-WES and were in all cases protein-truncating, mapping to exon 10 or exon 10-intron 10 junction, expected to escape NMD and cause selective abrogation of the autoinhibitory domain (aa 305-321) leading overall to gain-of-function.

Variation databases include pLoF CAMK4 variants albeit in all cases usptream or downstream of this region (pLI of this gene in gnomAD: 0.51). Variants leading to selective abrogation of the autoregulatory domain have not been reported.

Extensive evidence for the GoF effect of the variant has been provided in the first publication. Several previous studies have demonstrated that abrogation of the AID domain leads to consitutive activation (details below).

Mouse models - though corresponding to homozygous loss of function - support a role for CAMKIV in cognitive and motor symptoms. Null mice display tremulous and ataxic movements, deficiencies in balance and sensorimotor performance associated with reduced number of Purkinje neurons (Ribar et al 2000, PMID: 11069976 - not reviewed). Wei et al (2002, PMID: 12006982 - not reviewed) provided evidence for alteration in hippocampal physiology and memory function.

Heterozygous mutations in other genes for calcium/calmodulin-dependent protein kinases (CAMKs) e.g. CAMK2A/CAMK2B (encoding subunits of CAMKII) have been reported in individuals with ID.

---

The proband in the first publication (PMID: 30262571) was a male with DD, ID, behavioral difficulties (ASD, autoaggression, stereotypies) and hyperkinetic movement disorder (myoclonus, chorea, ataxia) with severe generalized dystonia (onset at the age of 13y). Brain MRI demonstrated cerebellar atrophy.

Extensive work-up incl. karyotyping, CMA, DYT-TOR1A, THAP1, GCH1, SCA1/2/3/6/7/8/12/17, Friedreich's ataxia and FMR1 analysis was negative.F

Trio WES identified a dn splice site variant (c.981+1G>A) in the last exon-intron junction. RT-PCR followed by gel electrophoresis and Sanger in fibroblasts from an affected and control subject revealed that the proband had - as predicted by the type/location of the variant - in equal amount 2 cDNA products, a normal as well as a truncated one.

Sequencing of the shortest revealed utilization of a cryptic donor splice site upstream of the mutated donor leading to a 77bp out-of-frame deletion and introduction of a premature stop codon in the last codon (p.Lys303Serfs*28). Western blot in fibroblast cell lines revealed 2 bands corresponding to the normal protein product as well as to the p.Lys303Serfs*28 although expression of the latter was lower than that of the full length protein.

Several previous studies have shown that mutant CAMKIV species that lack the autoinhibitory domain are consitutively active (several Refs provided). Among others Chatila et al (1996, PMID: 8702940) studied an in vitro-engineered truncation mutant (Δ1-317 - truncation at position 317 of the protein) with functionally validated gain-of-function effect.

To prove enhanced activity of the splicing variant, Zech et al assessed phosphorylation of CREB (cyclic AMP-responsive element binding protein), a downstream substrate of CAMKIV. Immunobloting revealed significant increase of CREB phosphorylation in patient fibroblasts compared to controls. Overactivation of CAMKIV signaling was reversed when cells were treated with STO-609 an inhibitor of CAMKK, the ustream activator of CAMKIV.

Overall the authors demonstrated that loss of CAMKIV autoregulatory domain due to this splice variant had a gain-of-function effect.

----

Following trio-WES, Zech et al (2020 - PMID: 33098801) identified another relevant subject within cohort of 764 individuals with dystonia. This 12-y.o. male, harboring a different variant affecting the same donor site (c.981+1G>T), presented DD, ID, dystonia (onset at 3y) and additional movement disorders (myoclonus, ataxia) as well as similar behavior (ASD, autoaggression, stereotypies). [Details in suppl. p20].

----

Finally Zech et al (2020 - PMID: 33211350) reported on a 24-y.o. woman with adolescence onset choreodystonia. Other features included DD, moderate ID, absence seizures in infancy, OCD with anxiety and later diagnosis of ASD. Trio WES revealed a dn stopgain variant (c.940C>T; p.Gln314*).

Added comment: 6 unrelated individuals
1x individual in a dystonia cohort index case with infancy-onset dystonia and other neurological manifestations with a de-novo missense variant, c.338G>A (p.Gly113Glu) in IMPDH2, predicted to disrupt an invariant residue within the cystathionine-β-synthase (CBS) domain pair of the encoded protein.
IMPDH2 encodes IMPDH2, a key enzyme in the purine biosynthetic pathway, expressed throughout the brain and not linked previously to any human Mendelian condition.
1x individual with a de-novo substitution, c.337G>A (p.Gly113Arg), was found in in-house whole-exome sequencing data from 500 individuals with neurodevelopmental disorders. Through GeneMatcher, de novo variants identified:
3 x missense: c.729G>C (p.Gln243His), c.619G>C (p.Gly207Arg), and c.619G>A (p.Gly207Arg)
1 x deletion: c.478_480delTCC (p.Ser160del)
The six variants were predicted to be deleterious and none of them seen in control databases. All affected conserved amino acids and resided in and around the cystathionine-β-synthase domain pair.
The described variants are situated in and around the CBS domain pair, a regulatory element in which clustering of pathogenic missense variants has already been shown for the homologue of IMPDH2, IMPDH1.

The variant carriers shared similar neurodevelopmental phenotypes. Apart from the dystonia cohort index case, one participant had evidence of dystonic posturing. Modelling of the variants on 3D protein structures revealed spatial clustering near specific functional sites, predicted to result in deregulation of IMPDH2 activity. Additionally, thermal-shift assays showed that the c.619G>A (p.Gly207Arg) variant, identified as within the CBS domain pair, and c.729G>C (p.Gln243His), which is in close vicinity, affected the stability or folding behaviour of IMPDH2.

PMID: 33891002 - Khol et al 2021 - report 3 unrelated families with duplications of a region covering the genes IRX5 and IRX6 completely, and the proximal exons of MMP2 and cone dystrophy. They propose that overexpression of IRX5 and IRX6 may be the cause of the disease, and this is supported by expression analysis in patient-derived fibroblasts and zebrafish experiments.

Initial family is a large 5 generation German family with 14 members with autosomal dominant cone dystrophy in which a 600kb duplicated region covering IRX5/IRX6 and part of MMP2 was identified. 2 additional families of Chinese and Dutch descent with copy number gains of ~700 and ~850 kb, covering the same region were then identified. The smallest region of overlap is 608kb. In addition another family of German decent is reported with adCD and the same duplication as the first German family. It is not known if they are distantly related. Segregation analysis on available members of all families showed the duplication in affected members and not in unaffected.

They find that IRX5, IRX6 and MMP2 are expressed in human adult retina. Several lincRNA within the locus are also expressed. In patient derived fibroblasts IRX5 and IRX6 showed increased expression levels. Over expression of IRX5 and IRX6 results in impaired visual performance in zebrafish larvae.

Phenotypes for gene: EPHA7 were set to Intellectual disability
Review for gene: EPHA7 was set to AMBER
Added comment: Lévy et al (2021 - PMID: 34176129) provide evidence that haploinssuficiency of EPHA7 results in a neurodevelopmental disorder.

The authors report on 12 individuals belonging to 9 unrelated families, all harboring with 6q microdeletions spanning EPHA7.

Overlapping features included DD (13/13), ID (10/10 - mild in most cases, individuals with larger CNVs/additional variants had more severe phenotype), speech delay and behavioral disorders. Variable other features incl. hypotonia (70%), non specific facial features, eye abnormalities (40%) and cardiac defects (25%).

The CNVs ranged from 152 kb to few Mb in size but in 4 subjects (P5-8) were only minimal, involving only EPHA7.

9 out of 12 individuals had inherited the deletion (5 subjects paternal, 4 maternal), in 1 subject (P12) this occured de novo, while for 2 others inheritance was not specified. Most deletions were inherited from an unaffected parent (in 6/7 families), with unclear contribution in a further one.

The authors discuss on previous studies suggesting an important role for EphA7 in brain development (modulation of cell-cell adhesion and repulsion, regulation of dendrite morphogenesis in early corticogenesis, role in dendritic spine formation later in development. EphA7 has also been proposed to drive neuronal maturation and synaptic function).

Haploinsufficiency for other ephrins or ephrin receptors has been implicated in other NDDs.

Overall Lévy et al promote incomplete penetrance and variable expressivity with haploinsufficiency of this gene being a risk factor for NDD. [The gene has also an %HI of 2.76% and a pLI of 1].

However two other affected siblings did not have this variant. This variant was also reported by Chen et al.

The phenotype is highly variable, but most patients have features of a systemic vascular inflammatory disorder with skin ulceration and recurrent strokes affecting the small vessels of the brain resulting in neurologic dysfunction. Other features may include recurrent fever, elevated acute-phase proteins, myalgias, lesions resembling polyarteritis nodosa, and/or livedo racemosa or reticularis with an inflammatory vasculitis on biopsy. Some patients may have renal and/or gastrointestinal involvement, hypertension, aneurysms, or ischemic necrosis of the digits. Some affected individuals have immunodeficiency. At least 10 unrelated families reported, the p.Gly47Arg variant is a common founder variant in the Jewish population.

Review for gene: MCM7 was set to AMBER
Added comment: MCM7 is a component of the MCM complex, a DNA helicase which is essential for DNA replication. Other components have been linked to disease with phenotypes including microcephaly and ID. MCM7 is not associated with any phenotype in OMIM or G2P at present.
------
Currently there are 3 unrelated pedigrees in literature with different biallelic MCM7 variants associated with disease (see below). Although there is some functional data in support of variant-level deleteriousness or gene-level pathogenicity, the clinical gestalt is very different between the 3 families.

- PMID: 33654309 (2021) - Two unrelated individuals with different compound het variants in MCM7 but disparate clinical features. One patient had typical Meier-Gorlin syndrome (including growth retardation, microcephaly, congenital lung emphysema, absent breast development, microtia, facial dysmorphism) whereas the second case had a multi-system disorder with neonatal progeroid appearance, lipodystrophy and adrenal insufficiency. While small at birth, the second patient did not demonstrate reduced stature or microcephaly at age 14.5 years. Both individuals had normal neurodevelopment.
Functional studies using patient-derived fibroblasts demonstrate that the identified MCM7 variants were deleterious at either transcript or protein levels and through interfering with MCM complex formation, impact efficiency of S phase progression.

- PMID: 34059554 (2021) - Homozygous missense variant identified in three affected individuals from a consanguineous family with severe primary microcephaly, severe ID and behavioural abnormalities. Knockdown of Mcm7 in mouse neuroblastoma cells lead to reduced cell viability and proliferation with increased apoptosis, which were rescued by overexpression of wild-type but not mutant MCM7.

- PMID: 29016857 (2017) - Homozygosity mapping of disease loci combined with WES in a single male from a consanguineous family presenting with lethal AMC revealed a homozygous frameshift deletion in UNC50 gene (c.750_751del:p.Cys251Phefs*4). Functional studies in C. elegans showed the variant caused loss of acetylcholine receptor expression in the muscle.

- PMID: 33820833 (2021) - Single individual reported with the same homozygous c.750_751del:p.Cys251Phefs*4 variant in UNC50 as previously described. The case was identified from a cohort of 315 genetically undiagnosed and unrelated AMC families. Arthrogryposis and tetra ventricular dilation were detected prenatally.

-- Note: it isn't definitively clear whether these are different individuals. Both are singleton males born to consanguineous parents, with the same variant and similar phenotype. Also both infants died at 28 w.g. However, the 2021 paper (PMID:33820833) states their patient was selected from a cohort of cases without a molecular diagnosis and indicate the UNC50 gene had already previously been identified in relation to this phenotype, highlighting the earlier paper (PMID:29016857). There is also no mention of tetra ventricular dilation in the first case, so it is likely that these do represent distinct individuals. Additional cases needed to provide clarity.

1 case with asphyxiating thoracic dystrophy (ATD) syndrome and infantile‐onset diabetes. Whole exome sequencing revealed a homozygous frameshift variant in the PDIA6 gene. RNA expression was reduced in a gene dosage‐dependent manner, supporting a loss‐of‐function effect of this variant. Phenotypic correlation with the previously reported mouse model recapitulated the growth defect and delay, early lethality, coagulation, diabetes, immunological, and polycystic kidney disease phenotypes. The phenotype of the current patient is consistent with phenotypes associated with the disruption of PDIA6 and the sensors of UPR in mice and humans.

Added comment: An 8‐months‐old male with developmental delay, microcephaly, subtle dysmorphism, hypotonia, pontocerebellar hypoplasia and delayed myelination. Similarly affected elder sibling succumbed at the age of 4‐years 6‐months. Exome sequencing revealed a homozygous missense variant (c.104C >T, p.Ser35Leu) in EXOSC1. In silico mutagenesis revealed loss of a polar contact with neighbouring Leu37 residue. Quantitative real‐time PCR indicated no appreciable differences in EXOSC1 transcript levels. Immunoblotting and blue native PAGE revealed reduction in the EXOSC1 protein levels and EXO9 complex in the proband, respectively. Of note, bi‐allelic variants in other exosome subunits EXOSC3, EXOSC8 and EXOSC9 have been reported to cause pontocerebellar hypoplasia type 1B, type 1C and type 1D, respectively.

Exome sequencing identified biallelic loss-of-function variants in UBE4A in the 4 families, with variants segregating with disease and parents carriers. They demonstrated that UBE4A loss-of-function variants reduced RNA expression and protein levels in clinical samples. Mice generated to mimic patient-specific Ube4a loss-of-function variant exhibited muscular and neurological/behavioural abnormalities, some of which are suggestive of the clinical abnormalities seen in the affected individuals.

Added comment: 3 individuals from 2 families with severe developmental delay, variable brain anomalies, congenital heart defects, dysmorphic facial features, and a distinctive type of synpolydactyly with an additional hypoplastic digit between the fourth and fifth digits of hands and/or feet. Exome sequencing identified different homozygous truncating variants in MAPKAPK5 in both families, segregating with disease and unaffected parents as carriers.

Patient-derived cells showed no expression of MAPKAPK5 protein isoforms and reduced levels of the MAPKAPK5-interacting protein ERK3. F-actin recovery after latrunculin B treatment was found to be less efficient in patient-derived fibroblasts than in control cells, supporting a role of MAPKAPK5 in F-actin polymerization.

Type A NPD patients exhibit hepatosplenomegaly in infancy and profound CNS involvement. They rarely survive beyond 2-3years of age. Type B patients also have hepatosplenomegaly and pathologic alterations of their lungs, but there are usually no CNS signs. The age of onset and rate of disease progression varies greatly among type B patients, and they frequently live into adulthood. Intermediate patients also have been reported with mild to moderate neurological findings.

The PSAP gene encodes saposins A, B, C and D. Variants resulting in PSAP null allele can be shared in patients with the deficit of other saposins (A-D) or whole prosaposin. The patient's phenotype depends then on the nature of the second allele - atypical Gaucher disease in case of saposin A, MLD in case of saposin B, and Krabbe disease in case of saposin C impairing mutations. The clinically most severe prosaposin deficit is caused by the presence of two PSAP null alleles.

Added comment: Six different truncating variants identified in 15 affected individuals from six families (biallelic inheritance). Disease manifested in childhood or adulthood with proximal and distal muscle weakness predominantly of the lower limbs. Myopathological and neurophysiological findings were indicative of combined neurogenic and myopathic pathology. Early childhood foot deformity was frequent, but no sensory signs were observed.

An additional 17 individuals from 15 families with hereditary motor neuropathy were identified. A 10-bp repeat expansion at the end of exon 1 was observed in 14 families and was homozygous in 10 of them. This mutation, c.62_71dup [p.Gly25Argfs*74], leads to a frameshift that results in a reduction in VWA1 transcript levels via nonsense-mediated decay.

Mendeliome v0.7056 CCDC88C Paul De Fazio changed review comment from: Heterozygous missense variant (gnomad: 1 het) reported in a 48-year-old Sudanese female presented with pure early onset hereditary spastic paraplegia. In contrast to previous reports, she developed neurological symptoms in early childhood and showed neither features of cerebellar ataxia, extrapyramidal signs, nor evidence of intellectual involvement. Functional studies showed the varaint induced JNK hyper-phosphorylation and enhanced apoptosis. 4 unaffected family members did not have the variant.

This phenotype appears to be sufficiently dissimilar to the 2 previously reported SCA families to not constitute a 3rd supporting report in that context.; to: Heterozygous missense variant (gnomad: 1 het) reported in a 48-year-old Sudanese female presented with pure early onset hereditary spastic paraplegia.

Added comment: - PMID: 33060134 (2020) - From a cohort of 220 families with microcephalic dwarfism spectrum disorders (OFC ≤−4 SD; height ≤−2 SD), three families (4 individuals) were identified with the same homozygous intronic variant (c.638+36C>G) in PRIM1. This variant was present in gnomAD in 2 individuals across all populations, but only in a heterozygous state. Haplotype analysis indicated that all three families share a distant common ancestor - i.e. confirmed founder variant.
Authors subsequently identified a single individual with compound heterozygous PRIM1 variants (c.103+1G>T, c.901T>C) from the DDD study, who also presented microcephaly and short stature (OFC ≤−3 SD; height ≤−3 SD).

Clinical overlap was evident in all 5 individuals, presenting extreme pre- and postnatal growth restriction, severe microcephaly (OFC −6.0 ± 1.5 SD) with simplified gyri appearance, hypothyroidism, hypo/agammaglobulinemia, and lymphopenia accompanied by intermittent anaemia/thrombocytopenia. All had chronic respiratory symptoms, and four died in early childhood from respiratory or GI infections.

Functional studies demonstrated reduced PRIM1 protein levels, replication fork defects and prolonged S-phase duration in PRIM1-deficient cells. The resulting delay to the cell cycle and inability to sustain sufficient cell proliferation provides a likely mechanism for the presenting phenotype.

Mendeliome v0.6901 SPINT2 Zornitza Stark changed review comment from: More than 15 unrelated families reported.; to: Well established gene-disease association. PMID 30445423 reviews 34 patients from 26 families: 13 different variants in SPINT2 were seen, including 3 premature termination codons, 2 start codon removals, and 3 canonical splice site variants, supporting loss of function as the pathogenic mechanism. The most commonly observed variant was Y163C, observed in 40 (59%) of 68 disease alleles. Seven unrelated patients with the Y163C mutation had a shared haplotype, suggesting that it is a founder mutation. Choanal atresia (20/34) and keratitis of infantile onset (26/34) were the most common findings. All patients presented with intractable diarrhoea, with onset typically in the first 2 weeks of life. Episodes of intestinal pseudoobstruction sometimes preceded the onset of diarrhoea. Characteristic epithelial tufts on intestinal histology were seen in 13 of the 34 patients.

Added comment: 12 individuals from 9 unrelated families in a cohort submitted for publication with bi-allelic IPO8 variants. Variants were nonsense/splice and some missense. Patients displayed a phenotype reminiscent of Loeys Dietz syndrome that variably combined cardiovascular, neurologic, skeletal and immunologic abnormalities along with dysmorphic features. Western blot on patient cells (4 individuals) showed reduced IPO8 expression. Disruption of IPO8 homologue in zebrafish associated with cardiac anomalies. Transcriptome analysis in zebrafish showed that IPO8-deficient zebrafish had abnormal TGFbeta pathway expression.

Mendeliome v0.6808 SATB1 Zornitza Stark edited their review of gene: SATB1: Added comment: Kohlschutter-Tonz syndrome-like (KTZSL) is characterized by global developmental delay with moderately to severely impaired intellectual development, poor or absent speech, and delayed motor skills. Although the severity of the disorder varies, many patients are nonverbal and have hypotonia with inability to sit or walk. Early-onset epilepsy is common and may be refractory to treatment, leading to epileptic encephalopathy and further interruption of developmental progress. Most patients have feeding difficulties with poor overall growth and dysmorphic facial features, as well as significant dental anomalies resembling amelogenesis imperfecta. This phenotype was reported in 28 patients (patients 13 to 40, PMID 33513338), including 9 patients from 3 families. Most variants were de novo, though some were inherited, suggestive of incomplete penetrance and variable expressivity.; Changed phenotypes: Developmental delay with dysmorphic facies and dental anomalies, MIM# 619228, Kohlschutter-Tonz syndrome-like, MIM# 619229

Added comment: Immunodeficiency-77 (IMD77) is an immunologic disorder characterized by recurrent and persistent polymicrobial infections with multiple unusual organisms. Skin and pulmonary infections are the most common, consistent with increased susceptibility to epithelial cell infections. The age at onset is highly variable: some patients have recurrent infections from childhood, whereas others present in late adulthood. The limited number of reported patients are all female, suggesting incomplete penetrance or a possible sex-influenced trait. Patient cells, mainly macrophages, show impaired killing of intracellular bacteria and organisms, including nontubercular mycobacteria, although there is also impaired killing of other organisms, such as Pseudomonas, Candida, and Aspergillus.

Four individuals reported, functional data, including animal model.

Review for gene: ALDH1L2 was set to RED
Added comment: Individual reported with bialleleic ALDH1L2 variants (non-canonical splice and a frameshift mutation), who also has a de novo hemizygous RPS6KA3 frameshift mutation. Authors state that not all features of the individual could be explained by the RPS6KA3 variant, and that consideration of Coffin-Lowry sysndrome was only made after identification of the RPS6KA3 variant. Therefore individual has there is a blended phenotype of Coffin–Lowry syndrome and Sjögren–Larsson syndrome. From functional studies authors propose that the ALDH1L2 loss induces mitochondrial dysfunction due to reduced NADPH and increased oxidative stress (PMID: 31341639). Knockout mouse model was viable and did not show an apparent phenotype, however metabolomic analysis showed vastly changed metabotypes in the liver and plasma in these mice suggesting channeling of fatty acids away from β-oxidation. Authors therefore postulate that the role of ALDH1L2 in the lipid metabolism explains why the loss of this enzyme is associated with neuro-cutaneous disease.

Ceramide is a proapoptotic lipid as high levels of ceramides can lead to apoptosis of neuronal cells, including photoreceptors. Variants segregated with disease. TLCD3B showed high expression in the adult retina with higher expression in the macular than in the peripheral region. Tlcd3bKO/KO mice exhibited a significant reduction of the cone photoreceptor light responses, thinning of the outer nuclear layer, and loss of cone photoreceptors across the retina.

A recurrent two‐base pair deletion (c.426_427delGA, p.K143Sfs*15) in the UBAP1 gene was found in four families, and a similar variant (c.475_476delTT, p.F159*) was detected in a fifth family. The variant was confirmed to be de novo in two families and inherited from an affected parent in two other families. RNA studies performed in lymphocytes from one patient with the de novo c.426_427delGA variant demonstrated escape of nonsense‐mediated decay of the UBAP1 mutant transcript, suggesting the generation of a truncated protein. Both variants identified are predicted to result in truncated proteins losing the capacity of binding to ubiquitinated proteins, hence appearing to exhibit a dominant‐negative effect on the normal function of the endosome‐specific endosomal sorting complexes required for the transport‐I complex.; to: PMID 31696996: Five unrelated families reported with childhood-onset HSP.

Added comment: Three unrelated families reported (though two shown to be related by descent) with predominantly a skeletal phenotype comprising mesomelic shortening and deformation of the lower limbs due to severe hypoplasia of the tibia and fibula. This was accompanied by abnormalities of the digits of the hands and feet, with cutaneous and osseous syndactyly as well as dysplastic, missing, and/or volar nails. In addition, genitourinary anomalies were observed in some. Homozygous deletions identified in all, with the minimal deleted region being a 27-kb interval (chr2: 118,561,492-118,589,320) located approximately 300 kb upstream of the EN1 gene. Mouse model recapitulated the phenotype.

Added comment: 6 individuals of a large consanguineous family presented in the neonatal period with recurrent vomiting and diarrhea, leading to severe FTT. Autozygosity mapping and WES identified homozygous variant (c.1358C>A:p.(Thr453Lys) in ACSL5. Segregated with affected individuals. Functional in vitro analysis of the ACSL5 variant by immunofluorescence, western blotting and enzyme assay suggested that Thr453Lys is a loss‐of‐function mutation without any remaining activity. Affected individuals were treated with total parenteral nutrition or medium‐chain triglyceride‐based formula restricted in long‐chain triglycerides. They responded well and follow up suggests that treatment is only required during early life.

Added comment: - PMID: 32439808 (2021) - Three generation family with c.350T>C variant in APOO, encoding a component of the MICOS complex which plays a role in maintaining inner mitochondrial membrane architecture.
Phenotypes include fatigue and muscle weakness (6/8), learning difficulties and cognitive impairment (4/8), and increased blood lactate (2/8). Four individuals were asymptomatic carriers, including one male (authors indicate variability in female carriers was due to skewed X-inactivation, although skewing studies were inconclusive in some cases). Variability in clinical presentation suggests reduced penetrance or possible contribution of additional factors.
Functional studies showed altered MICOS assembly and abnormalities in mitochondria ultrastructure in patient-derived fibroblasts. Knockdown studies in Drosophila and yeast demonstrated mitochondrial structural and functional deficiencies.

In vitro functional assays of the variant suggested a deleterious effect on the protein. Additionally cellular assays suggested a role for the gene in neural crest development and in the genesis of pain and touch sensing neurons.

PMID: 29402896 - more in depth functional assays and proteomic analyses suggesting a role for the protein in regulating sensory neuron differentiation in the human peripheral system

Other reports of associations with limited evidence:
PMID: 22511880 - Identified as a candidate gene in an autism study, but the homozygous variant (reported as R125C, but actually R1165C) has 40 homozygotes in gnomAD v2.1. And many of the other compound heterozygous candidate variants in the study are too common in gnomAD v2.1, with many homozygotes present. The missense reported in the pain insensitivity family Glu330Lys was reported with another rare missense variant (Glu1310Lys) in one of the autism cases, but no other phenotype information was provided.

PMID: 31354784 - a single case with infantile spasm reported with compound het missense (Met1316Val & Arg1165Cys), but both are very common in gnomAD v2.1 with 33,000 and 40 homozygotes, respectively.

Added comment: PMID: 33105483 - Khanshour et al 20201 - GWAS study of isolated Talipes equinovarus (clubfoot, iTEV) identified an associated locus within FSTL5. They show that Fstl5 is expressed in the embryonic hindlimb in bats, chicks and mice. However, Fstl5 was expressed more highly in neural tissues in mice, and rats lacking Fstl5 showed no gross developmental malformations. Conditional overexpression of Fstl5 in osteochondroprogenitors resulted in sexually dimorphic differences in skeletal development in mice.

Added comment: PMID: 33326993 - Salazar da Silva et al 2020 - report a 5 generation Brazilian family with 15 individuals with non-syndromic, bilateral and progressive hearing loss. Using linkage analysis and then exome sequencing they identified a heterozygous variant in NCOA3 (NM_181659, c.2810C > G; p.Ser937Cys) that was found in the 7 analysed affected individuals. It was also found in 4 unaffected individuals but they are within the range of onset of hearing loss observed in the family. Expression of nco3 was found in the inner ear of mice and zebrafish. ncoa3-/- zebrafish showed subtle alterations in cartilage, mineral density and abnormal adult swimming behaviour, which may suggest the mechanism of pathogenicity.

All variants are absent from population databases. In family 1, the variant was inherited from the apparently unaffected mother, indicating reduced penetrance, and phenotypic variance within families was observed. Phenotypes covered cardiac, vertebral, renal, craniofacial and gastrointestinal systems. At least at least 5 of the patients affected had features in three component organs so can be considered a VACTERL association. Wbp11 heterozygous null mice had vertebral and renal anomalies.

Added comment: Two unrelated patients with different de novo loss of function variants identified in PMID 33417013:

Individual 1: intragenic deletion, phenotype included psychomotor retardation, ID, growth retardation, microcephaly, and facial features reminiscent of 22q deletion syndrome.
Individual 2: canonical splice variant, phenotype mostly confined to ASD

Another two de novo variants were identified in the literature by the authors of that paper, one stop-gain (DDD study, PMID 28135719) and one missense (large autism cohort, PMID 25363760).

PMID 33417013 also showed that HIRA knockdown in mice results in neurodevelopmental abnormalities.

Rated Green due to 4 unrelated individuals (albeit 2 in large cohort studies) and a mouse model. NB: HIRA is within the common 22q deletion region.

Added comment: 5 sibs from a consanguineous family identified to have biallelic deletion encompassing part of the PYCR1 gene and the coding region of the MYADML2 gene.

According to the authors: "All five affected sibs had the most common features of ARCL (autosomal recessive cutis laxa) but not many of the less common ones. We attributed the anomalies not typical for ARCL to MYADML2 deficit, because no other genetic defect possibly a candidate to underlie the skeletal phenotype was found."

Phenotype may still be explained by the PYCR1 deletion alone.

PMID: 21666694 - Lipoprotein profiles of the families of 4 individuals with CREB3L3 nonsense mutations showed a significantly elevated mean plasma TG level in 11 mutation carriers compared with 5 non-carrier first-degree relatives (9.67 ± 4.70 vs. 1.66 ± 0.55 mM, P = 0.021, Wilcoxon test). 3 of those families have the same variant - Lys245GlufsTer130, which has 126 (281,946 alleles) hets in gnomAD v2.1.
PMID: 32580631 - case-control analysis of nonmonogenic severe hypertriglyceridemia cases (N=265) vs normolipidemic controls (N=477), identified 5 cases with LoF variants (3 of whom had the Lys245GlufsTer130 frameshift) and none in controls. OR 20.2 (95% CI 1.11–366.1) p = 0.002, adjusted p = 0.03.
The frequency of Lys245GlufsTer130 is higher than expected for a dominant disorder, but other loss of function variants have been identified. The gene may be associated with variable penetrance. There are multiple supporting null mouse models with hyperlipidaemia.

Added comment: Three cases in two unrelated consanguineous families with homozygous loss of function variants. Multiple null model organisms recapitulate the human phenotype: Null mouse model had cystic kidneys, a phenotype common to ciliopathies. Reducing Cby levels in Xenopus laevis model reduced the density of multiciliated cells, the number of basal bodies per multiciliated cell, and the numbers of neural tube primary cilia; it also led to abnormal development of the neural crest, central nervous system, and pronephros. Depletion of cby1 in zebrafish results in ciliopathy‐related phenotypes.

The onset age of seizures was ranged from 6 to 15 months. Patients had different types of seizures, including focal seizures, generalized tonic-clonic seizures and tonic seizure. One patient showed typical autism spectrum disorder (ASD) symptoms. Electroencephalogram (EEG) findings presented as focal or multifocal discharges, sometimes spreading to generalization. Brain magnetic resonance imaging (MRI) abnormalities were present in each patient. Severe intellectual disability and language and motor developmental disorders were found in our patients, with all patients having poor language development and were nonverbal at last follow-up. All but one of the patients could walk independently in childhood, but the ability to walk independently in one patient had deteriorated with age. All patients had abnormal neurological exam findings, mostly signs of extrapyramidal system involvement.

Added comment: Two sibling pairs and three unrelated males reported who presented in infancy with intractable focal seizures and severe developmental delay.

The variants were located in the N-terminal domain of the A isoform of FGF13/FHF2 (FHF2A). The X-linked FHF2 gene (also known as FGF13) has alternative first exons which produce multiple protein isoforms that differ in their N-terminal sequence. The variants were located at highly conserved residues in the FHF2A inactivation particle that competes with the intrinsic fast inactivation mechanism of Nav channels. Functional characterization of mutant FHF2A co-expressed with wild-type Nav1.6 (SCN8A) revealed that mutant FHF2A proteins lost the ability to induce rapid-onset, long-term blockade of the channel while retaining pro-excitatory properties. These gain-of-function effects are likely to increase neuronal excitability consistent with the epileptic potential of FHF2 variants.

Added comment: One family reported (PMID:32576952) with biallelic (one missense, one nonsense) variants in DPH2, with phenotype similar to DPH1 deficiency.

Another family was previously reported with biallelic nonsense variants (PMID:27421267) with a comparable phenotype, this family also has biallelic variants in KALRN and the authors thought those variants more likely causative.

In vitro functional assays support reduced diphthamide synthesis activity for the variants identified in PMID:32576952.

PMID: 33186545 - 6x probands with de novo missense variants in the AAA domain. 5 of the variants were at amino acid position 284 (changes to Trp and Gly).
Demonstrated that the variants had a dominant-negative effect on VPS4A function.
"The six probands with de novo substitutions affecting Glu206 or Arg284 had a consistent phenotype characterized by severe DD, profound ID, and dystonia. Children were very delayed in establishing head control and none achieved independent walking. Other common findings were cerebellar hypoplasia (five individuals out of six, the other showing uncharacterized severe cerebral atrophy) with a variable degree of corpus callosum hypoplasia. One individual also had bilateral polymicrogyria. Epilepsy was present in three and dystonia in five subjects. Eye involvement was also a common finding, including congenital cataract, retinal dystrophy, and in one case congenital Leber amaurosis. Four individuals were diagnosed with hepatosplenomegaly and/or steatosis. Three subjects had anemia, which was characterized as dyserythropoietic in two. Severe feeding difficulties were present in four individuals, requiring assisted feeding in three. Two had sensorineural deafness. Severe growth retardation, generally for all parameters, was present in most cases. Notably, severe microcephaly (typically with Z scores < −5) was universal. Overall, the disorder seems to have a poor prognosis as two affected individuals died in childhood or early adult life."

Added comment: 8 individuals from 6 unrelated families reported with bi-allelic LOF variants. All presented with almost complete absence of motor and cognitive development, progressive or congenital microcephaly, spastic tetraplegia or dystonia, and vision impairments. For most, the first symptoms included neonatal severe axial hypotonia and epilepsy that started during the first months or years of life. Prenatal symptoms of microcephaly associated with increased thalami echogenicity were detected in one, while the seven other individuals presented with progressive microcephaly. Some exhibited rapidly progressive phenotype and the affected children died in their infancy or middle-childhood. Strikingly, all the affected children had a unique brain MRI showing a mild to severe PCH, fluid-filled posterior fossa, with dilated lateral ventricles. In addition, severe atrophy at the level of the basal ganglia or thalami often associated with typical T2 hypersignal were identified in all the patients MRI.

Supportive functional data showing accumulation of highly phosphorylated inositols, mostly inositol hexakisphosphate (IP6), detected in HEK293 cells, fibroblasts, iPSCs and differentiating neurons lacking MINPP1. In mutant cells, higher IP6 level is expected to be associated with an increased chelation of intracellular cations, such as iron or calcium, resulting in decreased levels of available ions.

Added comment: Not associated with a phenotype in OMIM.

PMID: 32969478 - Tian et al 2020 - performed Sanger sequencing of FKBP8 on DNA samples from 472 spina bifida (SB) affected fetuses and 565 unaffected controls. 5 different rare heterozygous variants (MAF ≤ 0.001) were identified among the SB patients, while no deleterious rare variants were identified in the controls. 4 of the variants are missense, the other is a stop-gain. 2 cases were in white-Hispanic patients while the other 3 were non-white Hispanic. Functional studies showed that p.Glu140* affected FKBP8 localization to the mitochondria and impaired its interaction with BCL2 ultimately leading to an increase in cellular apoptosis. p.Ser3Leu, p.Lys315Asn and p.Ala292Ser variants decreased FKBP8 protein level. Gene expression was studied in mouse Fkbp8-/- embryos and found to be abnormal. Previous mouse models have shown neural tube defects.

Sufficient cases to rate green, but only the FKBP8 gene looked at so perhaps some caution required while further evidence is gathered.

Added comment: Gene disease association first reported in 2013 in PMID 24094747, in a large multigenerational family. However, note the variant reported, p.Arg1028Ter is present in over 400 hets in gnomad. Another variant reported in same paper, p.Cys990Ser in three unrelated individuals, is present in over 300 hets in gnomad and 1 hom.

Two further variants reported in PMID 31555324, one is missense, p.Arg748His, present in 60 hets, and the other, p.Arg1028Ter, is present is the variant identified in the previous publication, present in over 400 hets.

These variant frequencies are out of keeping for a rare disorder.

Marbach et al. (2020 - medRxiv : https://doi.org/10.1101/2020.09.10.20190314 - last author : C. Schaaf) report 6 unrelated individuals with heterozygous missense PRKAR1B variants.

All presented formal ASD diagnosis (6/6), global developmental delay (6/6) and intellectual disability (all - formal evaluations were lacking though). Additional features included neurologic anomalies (movement disorders : dyspraxia, apraxia, clumsiness in all, with tremor/dystonia or involuntary movements as single occurrences). Three displayed high pain tolerance. Regression in speech was a feature in two. Additional behavior anomalies included ADHD (4-5/6) or aggression (3/6). There was no consistent pattern of malformations, physical anomalies or facial features (with the exception of uplsanted palpebral fissures reported in 4).

3 different missense variants were identified (NM_00116470:c.1003C>T - p.Arg335Trp, c.586G>A - p.Glu196Lys, c.500_501delAAinsTT - p.Gln167Leu) with Arg355Trp being a recurrent one within this cohort (4/6 subjects). A possible splicing effect may apply for the MNV. All variants are absent from gnomAD and the SNVs had CADD scores > 24.

In all cases were parental samples were available (5/6), the variant had occurred as a de novo event.

Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes. As the authors comment, the RIβ subunit is primarily expressed in brain with higher expression in cortex and hypothalamus.

The functional consequences of the variants at cellular level were not studied.

Previous studies have demonstrated that downregulation of RIβ in murine hippocampal cultures, reduced phosphorylation of CREB, a transcription factor involved in long-term memory formation. The authors speculate that a similar effect on cAMP/PKA/CREB cascade may mediate the cognitive effects in humans. RIβ deficient mice also display diminished nociceptive pain, similar to the human phenotype. [Several refs provided].

The authors cite the study by Kaplanis et al (2020 - PMID: 33057194), where in a large sample of 31,058 trio exomes of children with developmental disorders, PRKAR1B was among the genes with significant enrichment for de novo missense variants. [The gene has a pLI score of 0.18 in gnomAD / o/e = 0.26 - so pLoF variants may not be deleterious].

Please note that a specific PRKAR1B variant (NM_002735.2:c.149T>G - p.Leu50Arg) has been previous reported to segregate with a late-onset neurodegenerative disorder characterized by dementia and/or parkinsonism within a large pedigree with 12 affected individuals [Wong et al 2014 - PMID: 25414040].

Review for gene: MPP5 was set to GREEN
Added comment: Sterling et al (2020 - PMID: 33073849) provide information on the phenotype of 3 individuals with de novo MPP5 variants.

Common features included global developmental delay, intellectual disability (3/3 - severe in 2/3), speech delay/regression (the latter in at least 2) and behavioral abnormalities. Variable other features were reported, among others microcephaly (1/3), abnormal vision (1/3 : CVI, retinal dystrophy, nystagmus), brain MRI abnormalities (2/3), late-onset seizures (1/3). These subjects displayed variable and non-specific dysmorphic features.

All were investigated by exome sequencing (previous investigations not mentioned).

One subject was found to harbor a de novo mosaic (5/25 reads) stopgain variant, further confirmed by Sanger sequencing [NM_022474.4:c.1555C>T - p.(Arg519Ter). The specific variant is reported once in gnomAD (1/251338). Two de novo missense variants were identified in the remaining individuals [c.1289A>G - p.Glu430Gly / c.974A>C - p.His325Pro). All variants had in silico predictions in favor of a deleterious effect (CADD score >24).

The authors comment that MPP5 encodes an apical complex protein with asymmetric localization to the apical side of polarized cells. It is expressed in brain, peripheral nervous system and other tissues. MPP5 is a member of the membrane-associated guanylate kinase family of proteins (MAGUK p55 subfamily), determining cell polarity at tight junctions.

Previous animal models suggest that complete Mpp5(Pals1) KO in mice leads to near absence of cerebral cortical neurons. Htz KO display reduction in size of cerebral cortex and hippocampus. The gene is expressed in proliferating cell populations of cerebellum and important for establishment cerebellar architecture. Conditional KO of Mpp5(Pals1) in retinal progenitor cells mimics the retinal pathology observed in LCA. [Several refs. provided]

The authors studied a heterozygous CNS-specific Mpp5 KO mouse model. These mice presented microcephaly, decreased cerebellar volume and cortical thickness, decreased ependymal cells and Mpp5 at the apical surface of cortical vertrical zone. The proportion of cortical cells undergoing apoptotic cell death was increased. Mice displayed behavioral abnormalities (hyperactivity) and visual deficits, with ERG traces further suggesting retinal blindness.

Overall the mouse model was thought to recapitulate the behavioral abnormalities observed in affected subjects as well as individual rare features such as microcephaly and abnormal vision.

Haploinsufficiency (rather than a dominant negative effect) is favored as the underlying disease mechanism. This is also in line with a dose dependent effect observed in mice.

Added comment: Palencia-Campos et al (2020 - PMID: 33058759) report on the phenotype of 3 individuals heterozygous for PRKACA and 4 individuals heterozygous for PRKACB pathogenic variants.

The most characteristic features in all individuals with PRKACA/PRKACB mutation, included postaxial polydactyly of hands (6/7 bilateral, 1/7 unilateral) and feet (4/7 bilateral, 1/7 unilateral), brachydactyly and congenital heart defects (CHD 5/7) namely a common atrium or AVSD. Two individuals with PRKACA variant who did not have CHD had offspring with the same variant and an AVSD.

Other variably occurring features included short stature, limbs, narrow chest, abnormal teeth, oral frenula, nail dysplasia. One individual with PRKACB variant presented tumors.

Intellectual disability was reported in 2/4 individuals with PRKACB variant (1/4: mild, 1/4: severe). The 3 individuals with PRKACA variant did not present ID.

As the phenotype was overall suggestive of Ellis-van Creveld syndrome (or the allelic Weyers acrofacial dysostosis), although these diagnoses were ruled out following analysis of EVC and EVC2 genes.

WES was carried out in all.

PRKACA : A single heterozygous missense variant was identified in 3 individuals from 3 families (NM_002730.4:c.409G>A / p.Gly137Arg) with 1 of the probands harboring the variant in mosaic state (28% of reads) and having 2 similarly affected offspring. The variant was de novo in one individual and inherited in a third one having a similarly affected fetus (narrow thorax, postaxial polyd, AVSD).

PRKACB : 4 different variants were identified (NM_002731.3: p.His88Arg/Asn, p.Gly235Arg, c.161C>T - p.Ser54Leu). One of the individuals was mosaic for the latter variant, while in all other cases the variant had occurred de novo.

Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes.

The authors provide evidence that the variants confer increased sensitivity of PKA holoenzymes to activation by cAMP (compared to wt).

By performing ectopic expression of wt or mt PRKACA/B (variants studied : PRKACA p.Gly137Arg / PRKACB p.Gly235Arg) in NIH 3T3 fibroblasts, the authors demonstrate that inhibition of hedgehog signaling likely underlyies the developmental defects observed in affected individuals.

As for PRKACA, the authors cite another study where a 31-month old female with EvC syndrome diagnosis was found to harbor the aforementioned variant (NM_001304349.1:c.637G>A:p.Gly213Arg corresponding to NM_002730.4:c.409G>A / p.Gly137Arg) as a de novo event. Without additional evidence at the time, the variant was considered to be a candidate for this subject's phenotype (Monies et al 2019 – PMID: 31130284).

Added comment: Palencia-Campos et al (2020 - PMID: 33058759) report on the phenotype of 3 individuals heterozygous for PRKACA and 4 individuals heterozygous for PRKACB pathogenic variants.

The most characteristic features in all individuals with PRKACA/PRKACB mutation, included postaxial polydactyly of hands (6/7 bilateral, 1/7 unilateral) and feet (4/7 bilateral, 1/7 unilateral), brachydactyly and congenital heart defects (CHD 5/7) namely a common atrium or AVSD. Two individuals with PRKACA variant who did not have CHD had offspring with the same variant and an AVSD.

Other variably occurring features included short stature, limbs, narrow chest, abnormal teeth, oral frenula, nail dysplasia. One individual with PRKACB variant presented tumors.

Intellectual disability was reported in 2/4 individuals with PRKACB variant (1/4: mild, 1/4: severe). The 3 individuals with PRKACA variant did not present ID.

As the phenotype was overall suggestive of Ellis-van Creveld syndrome (or the allelic Weyers acrofacial dysostosis), although these diagnoses were ruled out following analysis of EVC and EVC2 genes.

WES was carried out in all.

PRKACA : A single heterozygous missense variant was identified in 3 individuals from 3 families (NM_002730.4:c.409G>A / p.Gly137Arg) with 1 of the probands harboring the variant in mosaic state (28% of reads) and having 2 similarly affected offspring. The variant was de novo in one individual and inherited in a third one having a similarly affected fetus (narrow thorax, postaxial polyd, AVSD).

PRKACB : 4 different variants were identified (NM_002731.3: p.His88Arg/Asn, p.Gly235Arg, c.161C>T - p.Ser54Leu). One of the individuals was mosaic for the latter variant, while in all other cases the variant had occurred de novo.

Protein kinase A (PKA) is a tetrameric holoenzyme formed by the association of 2 catalytic (C) subunits with a regulatory (R) subunit dimer. Activation of PKA is achieved through binding of 2 cAMP molecules to each R-subunit, and unleashing(/dissociation) of C-subunits to engage substrates. PRKACA/B genes encode the Cα- and Cβ-subunits while the 4 functionally non-redundant regulatory subunits are encoded by PRKAR1A/1B/2A/2B genes.

The authors provide evidence that the variants confer increased sensitivity of PKA holoenzymes to activation by cAMP (compared to wt).

By performing ectopic expression of wt or mt PRKACA/B (variants studied : PRKACA p.Gly137Arg / PRKACB p.Gly235Arg) in NIH 3T3 fibroblasts, the authors demonstrate that inhibition of hedgehog signaling likely underlyies the developmental defects observed in affected individuals.

Without additional evidence at the time, the variant was considered to be a candidate for this subject's phenotype (Monies et al 2019 – PMID: 31130284).

Gold et al (2020 - PMID: 33009664) report 5 individuals with CSNK1G1 variants, including updated information on a previously reported subject (Martin et al 2014 - PMID: 24463883).

Features included DD (5/5) with associated expressive language delay, ASD (in at least 3/5), seizures (2/5), dysmorphic facial features (4/5 arched eyebrows, 3/5 prominent central incisors, 2/5 epicanthus) and limb anomalies (2/5 - proximally placed thumb, 5th f. clinodactyly, asymmetric overgrowth - the other individual had tapering fingers). GI problems were observed in 4/5. Two individuals had macrocephaly and one had microcephaly. There was no formal developmental assessment although ID might be implied in at least 3 individuals (p1: 20y - single words/regression in walking following a seizure episode, p2: 8y - first words at 5y, assistance to feed, dress and bathe, ASD, p4: 13y - regression, assistance to feed and dress).

CSNK1G1 encodes the gamma-1 isoform of casein kinase 1, a protein involved in growth and cell morphogenesis. The gene has ubiquitous expression, incl. brain. As commented, in brain it regulates phosphorylation of NMDA receptors, playing a role in synaptic transmission (4 articles cited).

One individual had a 1.2 kb deletion spanning exon 3 of CSNK1G1 [chr15:64550952-64552120 - GRCh37]. Parental samples were unavailable for this individual. Four individuals were found to harbor de novo CSNK1G1 variants [NM_022048.3: c.688C>T - p.(Arg230Trp) dn | c.1255C>T - p.(Gln419*) dn | c.1214+5G>A dn with in silico predictions in favor of splice disruption | c.419C>T - p.(Thr140Met) dn].

Arg230Trp is however present once in gnomAD. The stopgain variant is located in the last exon and predicted to skip NMD.

There were no variant studies performed.

The Drosophila gish gene encodes a CK1γ homolog with preferential expression in the mushroom body. Heterozygous and homozygous mutants exhibit impairment in memory retention, more severe in homozygous flies. gish was also identified as a seizure modifier in a fly epilepsy model (heterozygous para mt flies).

Added comment: ITFG2 was suggested to be a candidate gene for autosomal recessive ID in the study by Harripaul et al (2018 - PMID: 28397838). The authors performed microarray and exome sequencing in 192 consanguineous families and identified a homozygous ITGF2 stopgain variant (NM_018463.3:c.472G>T / p.Glu158*) along with 3 additional variants segregating with ID within an investigated family (PK51). Cheema et al (2020 - https://doi.org/10.1038/s41525-020-00150-z) report briefly on a male, born to consanguineous parents presenting with NDD, seizures, regression and ataxia. There was a similarly affected female sibling. Evaluation of ROH revealed a homozygous ITFG2 nonsense variant [NM_018463.3:c.361C>T / p.(Gln121*)]. Families in this study were investigated by trio WES or WGS. Evaluation of data of the same lab revealed 3 additional unrelated subjects with overlapping phenotypes, notably NDD and ataxia. These individuals were - each - homozygous for pLoF variants [NM_018463.3:c.848-1G>A; NM_018463.3:c.704dupC, p.(Ala236fs), NM_018463.3:c.1000_1001delAT, p.(Ile334fs)]. As discussed in OMIM, ITFG2 encodes a subunit of the KICSTOR protein complex, having a role in regulating nutrient sensing by MTOR complex-1 (Wolfson et al 2017 - PMID : 28199306).

All affected subjects presented similar phenotype incl. microcephaly at birth (5/5 with OFC < -2 SD though in 2/5 cases N OFC was observed later), DD and ID (1/5 mild-moderate, 1/5 moderate, 3/5 severe), motor dysfunction in the form of spastic (5/5) paraparesis, ataxia/dysmetria (3/4), intention tremor (in 3/?) and/or peripheral neuropathy (2 sibs). They exhibited corpus callosum hypoplasia (5/5) and perisylvian microgyria-like pattern (4/5). Cardiac problems were reported in all, with hypertrophic cardiomyopathy in 4/5 (from 3 families) and atrial-SD in the 5th individual (1/5). Common dysmorphic features incl. long palpebral/fissures, eversion of lateral third of lower eylids, arched eyebrows, long eyelashes, thin upper lip, short Vth finger, fetal pads, mild 2-3 toe syndactyly, proximally placed thumbs.

Biallelic variants were identified following exome sequencing in all (other investigations not mentioned). Identified variants were in all cases missense SNVs or in-frame del, which together with evidence from population databases and mouse model might suggest a hypomorphic effect of variants and intolerance/embryonic lethality for homozygous LoF ones.

SHMT2 encodes the mitohondrial form of serine hydroxymethyltransferase. The enzyme transfers one-carbon units from serine to tetrahydrofolate (THF) and generates glycine and 5,10,methylene-THF.

Mitochondrial defect was suggested by presence of ragged red fibers in myocardial biopsy of one patient. Quadriceps and myocardial biopsies of the same individual were overall suggestive of myopathic changes.

While plasma metabolites were within N range and SHMT2 protein levels not significantly altered in patient fibroblasts, the authors provide evidence for impaired enzymatic function eg. presence of the SHMT2 substrate (THF) in patient but not control (mitochondria-enriched) fibroblasts , decrease in glycine/serine ratios, impared folate metabolism. Patient fibroblasts displayed impaired oxidative capacity (reduced ATP levels in a medium without glucose, diminished oxygen consumption rates). Mitochondrial membrane potential and ROS levels were also suggestive of redox malfunction.

Shmt2 ko in mice was previously shown to be embryonically lethal attributed to severe mitochondrial respiration defects, although there was no observed brain metabolic defect.

The authors performed Shmt2 knockdown in motoneurons in Drosophila, demonstrating neuromuscular junction (# of satellite boutons) and motility defects (climbing distance/velocity).

Added comment: Single individual reported with homozygous canonical splice site variant resulting in exon 7 skipping, and global developmental delay and generalized dystonia. He attained a few words and voluntary limb movements but never sat unsupported. He had pale optic discs and an axonal neuropathy. From 6 years of age, his condition began to deteriorate, with reduced motor abilities and alertness. An MRI of the brain showed atrophy of the superior cerebellar vermis and slimming of the posterior limb of the corpus callosum. VPS41 is component of the HOPS complex and other genes in the complex have been implicated in movement disorders.

Progressive generalization ensued, although most remained ambulant, and only a minority (16%) lost the ability to walk in adulthood. Additional clinical features of mild to moderate intellectual disability and neuropsychiatric symptoms were present in approximately one‐third. In 4 individuals, magnetic resonance imaging (MRI) showed bilateral and symmetrical hypointensity of the globi pallidi and sometimes also the midbrain and dentate nuclei, suggestive of iron deposition. Mild generalized cerebral atrophy was also apparent in 4 individuals.

Defective assembly, stability, and function of ATP synthase observed using Lymphoblastoid cell lines from one of the families.

This finding indicated that the p.Arg53Trp mutation acted in synergy with the m.11778G>A mutation and deteriorated mitochondrial dysfunctions necessary for the expression of LHON.

Prickle3-deficient mice exhibited pronounced ATPase deficiencies.

Mendeliome v0.4747 HPDL Zornitza Stark commented on gene: HPDL: 17 individuals from 13 families, with a spectrum of neurologic impairment ranging from a severe congenital form without any neurological development (n = 2/17, 12%) to infantile-onset presentations (n = 10/17, 59%) with moderate to severe neurodevelopmental issues, partly with a pathology reminiscent of mitochondrial disease (Leigh-like syndrome), to juvenile-onset spastic paraplegia (n = 5/17, 29%).

Frequently observed clinical findings included chronic progression of neurological signs (n = 16/17, 94%), motor developmental delay (n = 12/17, 71%), intellectual impairment (n = 11/17, 65%), microcephaly (n = 9/16, 56%), and seizures/epilepsy (n = 9/17, 53%). Other relevant clinical findings were visual disturbances/strabismus (n = 9/17, 53%) and loss of developmental milestones (n = 6/17, 35%).

Acute central respiratory failure leading to life-threatening events requiring partly mechanically assisted ventilation occurred in half of individuals with infantile presentation (n = 5/10, 50%), respectively one third of all individuals (n = 5/17, 29%).

Demyelinating neuropathy was present in three individuals (n = 3/11, 27%), with reduced sensory nerve conduction velocity (NCV) in all and severely reduced motor NCV in one.

Added comment: 2 unrelated patients with mild oculocutaneous albinism, moderate bleeding diathesis, platelet aggregation deficit, and a dramatically decreased number of platelet dense granules, all signs compatible with HPS. Identified distinct homozygous variants in the BLOC1S5 gene (patient 1: deletion of exons 3 and 4, patient 2: 1-bp deletion in exon 4). Parental segregation confirmatory in patient 1, quantitative PCR analysis confirmatory in patient 2). Functional tests performed on platelets of one patient displayed an absence of the obligate multisubunit complex BLOC-1, showing that the variant disrupts BLOC1S5 function and impairs BLOC-1 assembly. Expression of the patient-derived BLOC1S5 deletion in nonpigmented murine Bloc1s5-/- melan-mu melanocytes failed to rescue pigmentation, the assembly of a functional BLOC-1 complex, and melanosome cargo trafficking, unlike the wild-type allele. Pathogenic variants in the genes encoding three other BLOC-1 subunits (DTNBP1, BLOC1S3, and BLOC1S6) underlie HPS types 7, 8, and 9 respectively.

--

Connaughton et al (2020 - PMID: 32891193) report on 19 individuals (from 15 unrelated families) with heterozygous pathogenic ZMYM2 variants.

Affected individuals from 7 families presented with CAKUT while all of them displayed extra-renal features. Neurological manifestations were reported in 16 individuals from 14 families (data not available for 1 fam), among others hypotonia (3/14 fam), speech delay (4/14 fam), global DD (9/14 fam), ID (4/14 fam), microcephaly (4/14 fam). ASD was reported in 4 fam (4 indiv). Seizures were reported in 2 fam (2 indiv). Variable other features included cardiac defects, facial dysmorphisms, small hands and feet with dys-/hypo-plastic nails and clinodactyly.

14 pLoF variants were identified, in most cases as de novo events (8 fam). In 2 families the variant was inherited from an affected parent. Germline mosaicism occurred in 1 family.

The human disease features were recapitulated in a X. tropicalis morpholino knockdown, with expression of truncating variants failing to rescue renal and craniofacial defects. Heterozygous Zmym2-deficient mice also recapitulated the features of CAKUT.

ZMYM2 (previously ZNF198) encodes a nuclear zinc finger protein localizing to the nucleus (and PML nuclear body).

It has previously been identified as transcriptional corepressor interacting with nuclear receptors and the LSD1-CoREST-HDAC1 complex. It has also been shown to interact with FOXP transcription factors.

The authors provide evidence for loss of interaction of the truncated ZMYM2 with FOXP1 (mutations in the latter having recently been reported in syndromic CAKUT).

Loss of MTX2 in patients' primary fibroblasts led to loss of Metaxin-1 (MTX1) and mitochondrial dysfunction, including network fragmentation and oxidative phosphorylation impairment. Furthermore, patients' fibroblasts were resistant to induced apoptosis, leading to increased cell senescence and mitophagy and reduced proliferation.

RREB1 recruits SIN3A and KDM1A to an RRE in target promoters in human and murine cells to control histone H3K4 methylation of MAPK pathway genes.

In summary, single well phenotyped individual with a CNV and experimental data to support gene-disease association.

PMID: 30120216 (2018) - Two unrelated probands with an identical homozygous missense (c.109G>T, p.Asp37Tyr) variant in TRAPPC2L. Both individuals presented neurodevelopmental delay, febrile illness-induced encephalopathy, and episodic rhabdomyolysis, followed by developmental arrest, seizures and tetraplegia. The variant segregated with the phenotype in each family, and haplotype analysis suggested a founder effect.

The mutant protein was expressed in patient fibroblasts, but displayed membrane trafficking delays. Studies in yeast showed that the variant impaired interaction with TRAPPC10, and increased levels of the active RAB11.


PMID: 32843486 (2020) - In an Ashkenazi Jewish family with three affected sibs with GDD/ID, WGS revealed a segregating homozygous missense variant (c.5G>C, p.Ala2Gly) in the TRAPPC2L gene. No seizures, brain MRI abnormalities, or illness provoked regression were documented in this family.

Comparable to the previous study, the variant resulted in delayed ER-to-Golgi trafficking and elevated levels of active RAB11. Studies using yeast and in vitro binding, showed that the variant disrupted interaction with another core TRAPP protein, TRAPPC6a.

Added comment: PMID 29868776: 8 affected individuals from 4 families reported. 7 were described to be postnatally microcephalic (at or below 3rd percentile). One was -5.1SD and one was -3.6SD. SD values for the others weren't provided.

The following head circumference measurements were provided for 6 of the affecteds:

51cm at 16yo; 50cm at 19yo; 42.5cm at 12mo, 45cm at 28mo, 45.2cm at 7yo; 45cm at 4yo.

3 of the families were consanguineous Saudi families with the same homozygous missense variant.

In vitro functional expression studies showed that both mutations caused impaired thioester binding with UFM1. Patient cells also showed decreased UFC1 intermediate formation with UFM1. The decrease in function was consistent with a hypomorphic allele, and the authors suggested that complete loss of function would be embryonic lethal.

PMID 30552426: 1 more individual with epileptic encephalopathy reported with a different homozygous missense variant in UFC1. The patient had microcephaly <3rd percentile.

Added comment: PMID: 31960911 - Gravesteijn et al 2020 - describe a family with a unique cysteine-altering NOTCH3 variant in exon 9 in 5 individuals, which is predicted to cause natural exon 9 skipping. This mimics the therapeutic NOTCH3 cysteine correction approach and allows the effect of cysteine corrective exon skipping on NOTCH3 protein aggregation and disease severity in humans to be studied. In this family the CADASIL phenotype was mild.

Added comment: 13 individuals with dn missense SNVs overall, overlapping features for 10 with available phenotype / a recurring variant has been identified in 2 different studies.

► Malhotra et al (2020 - PMID: 32820033) report on 10 unrelated individuals with de novo missense LMBRD2 variants. Features included DD (9/10), ID (6/8 of relevant age), microcephaly (7/10), seizures (5/10 - >=3 different variants), structural brain abnormalities (e.g. thin CC in 6/9), highly variable ocular abnormalities (5/10) and dysmorphic features in some (7/10 - nonspecific). All had variable prior non-diagnostic genetic tests (CMA, gene panel, mendeliome, karyotype). WES/WGS revealed LMBRD2 missense variants, in all cases de novo. A single individual had additional variants with weaker evidence of pathogenicity. 5 unique missense SNVs and 2 recurrent ones (NM_001007527:c.367T>C - p.Trp123Arg / c.1448G>A - p.Arg483His) were identified. These occurred in different exons. Variants were not present in gnomAD and all had several in silico predictions in favor of a deleterious effect. There was phenotypic variability among individuals with the same variant (e.g. seizures in 1/3 and microchephaly in 2/3 of those harboring R483H). The gene has a pLI of 0 (although o/e ranges from 0.23 to 0.55), %HI of 15.13 and z-score of 2.27. The authors presume that haploinsufficiency may not apply, and consider a gain-of-function/dominant-negative effect more likely. As the authors comment LMBRD2 (LMBR1 domain containing 2) encodes a membrane bound protein with poorly described function. It is widely expressed across tissues with notable expression in human brain (also in Drosophila, or Xenopus laevis). It displays high interspecies conservation. It has been suggested (Paek et al - PMID: 28388415) that LMBRD2 is a potential regulator of β2 adrenoreceptor signalling through involvement in GPCR signalling.

► Kaplanis et al (2020 - https://doi.org/10.1101/797787) in a dataset of 31058 parent-offspring trios (WES) previously identified 3 individuals with developmental disorder, harboring c.1448G>A - p.Arg483His. These individuals (1 from the DDD study, and 2 GeneDx patients) appear in Decipher. [ https://decipher.sanger.ac.uk/ddd/research-variant/40e17c78cc9655a6721006fc1e0c98db/overview ]. The preprint by Kaplanis et al is cited by Malhotra et al, with Arg483His reported in 6 patients overall in both studies.

Added comment: Knuutinen et al (2020 - PMID: 32779182) report on 2 individuals from 2 consanguineous families, homozygous for TAF1C missense variants. Both presented with an early onset neurological phenotype with severe global DD, ID (2/2 - moderate and profound), spasticity (2/2), ophthalmic findings (strabismus 2/2, nystagmus 1/2). Epilepsy, abnormal brain MRI (cerebral and cerebellar atrophy and white matter hyperintensities) as well and additional findings were reported in one (always the same individual). Following a normal CMA, exome in the first case revealed a homozygous missense SNV (NM_005679.3:c.1165C>T / p.Arg389Cys) supported by in silico predictions. mRNA and protein levels were substantially reduced in fibroblasts from this subject. Only the patient and parents were tested for the variant but not 3 unaffected sibs (fig1). The second individual was homozygous for another missense variant (p.Arg405Cys) also supported by in silico predictions. The girl was the single affected person within the family with an unaffected sib and parents heterozygous for the variant. Several other unaffected relatives in the extended pedigree were either carriers for this variant or homozygous for the wt allele. TAF1C encodes the TATA-box binding protein associated factor (TAF) RNA polymerase I subunit. RNA polymerase I (Pol I) transcribes genes to produce rRNA. For Pol I to initiate transcription, two transcription factors are required : UBF (upstream binding factor encoded by UBTF) and SL1 (selectivity factor 1). The latter is formed by TBP (TATA-binding protein) and 3 Pol I-specific TBP-associated factors (TAFs). A recurrent de novo missense variant in UBTF (encoding the other Pol I transcription factor) causes a disorder with highly similar features. The specific variant acts through a gain-of-function mechanism (and not by LoF which appears to apply for TAF1C based on expression data). The authors hypothesize that altered Pol I activity and resulting ribosomal stress could cause the microcephaly and leukodystrophy (both reported in 1 - the same - individual).

Publications for gene: FAM50A were set to 32703943

Review for gene: FAM50A was set to GREEN
Added comment: Lee et al (2020 - PMID: 32703943) provide evidence that Armfield X-Linked intellectual disability syndrome is caused by monoallelic FAM50A pathogenic variants. The current review is based only on this reference. The authors provide clinical details on 6 affected individuals from 5 families. Features included postnatal growth delay, DD and ID (6/6 - also evident for those without formal IQ assesment), seizures (3/6 from 2 families), prominent forehead with presence of other facial features and variable head circumference (5th to >97th %le), ocular anomalies (5/6 - strabismus/nystagmus/Axenfeld-Rieger), cardiac (3/6 - ASD/Fallot) and genitourinary anomalies (3/6). In the first of these families (Armfield et al 1999 - PMID: 10398235), linkage analysis followed by additional studies (Sanger, NGS of 718 genes on chrX, X-exome NGS - several refs provided) allowed the identification of a FAM50A variant. Variants in other families were identified by singleton (1 fam) or trio-ES (3 fam). In affected individuals from 3 families, the variant had occurred de novo. Carrier females in the other families were unaffected (based on pedigrees and/or the original publication). XCI was rather biased in most obligate carrier females from the 1st family (although this ranged from 95:5 to 60:40). Missense variants were reported in all affected subjects incl. Trp206Gly, Asp255Gly, Asp255Asn (dn), Glu254Gly (dn), Arg273Trp (dn) (NM_004699.3). Previous studies have demonstrated that FAM50A has ubiquitous expression in human fetal and adult tissues (incl. brain in fetal ones). Immunostaining suggests a nuclear localization for the protein (NIH/3T3 cells). Comparison of protein levels in LCLs from affected males and controls did not demonstrate significant differences. Protein localization for 3 variants (transfection of COS-7 cells) was shown to be similar to wt. Complementation studies in zebrafish provided evidence that the identified variants confer partial loss of function (rescue of the morpholino phenotype with co-injection of wt but not mt mRNA). The zebrafish ko model seemed to recapitulate the abnormal development of cephalic structures and was indicative of diminished/defective neurogenesis. Transcriptional dysregulation was demonstrated in zebrafish (altered levels and mis-splicing). Upregulation of spliceosome effectors was demonstrated in ko zebrafish. Similarly, mRNA expression and splicing defects were demonstrated in LCLs from affected individuals. FAM50A pulldown followed by mass spectrometry in transfected HEK293T cells demonstrated enrichment of binding proteins involved in RNA processing and co-immunoprecipitation assays (transfected U-87 cells) suggested that FAM50A interacts with spliceosome U5 and C-complex proteins. Overall aberrant spliceosome C-complex function is suggested as the underlying pathogenetic mechanism. Several other neurodevelopmental syndromes are caused by variants in genes encoding C-complex affiliated proteins (incl. EFTUD2, EIF4A3, THOC2, etc.).

Mendeliome v0.3675 PIGQ Zornitza Stark edited their review of gene: PIGQ: Added comment: Homozygous or compound heterozygous mutations in PIGQ cause Epileptic encephalopathy, early infantile, 77 (MIM #618548).

Johnstone et al (2020 - PMID: 32588908) describe the phenotype of 7 children (from 6 families) with biallelic PIGQ pathogenic variants. The authors also review the phenotype of 3 subjects previously reported in the literature (by Martin et al, Alazami et al, Starr et al - respective PMIDs: 24463883, 25558065, 31148362).

Affected individuals displayed severe to profound global DD/ID and seizures with onset in the first year of life. There were variable other features incl. - among others - genitourinary, cardiac, skeletal, ophthalmological anomalies, gastrointestinal issues. Within the cohort there was significant morbidity/mortality.

PIGQ encodes phosphatidylinositol glycan anchor biosynthesis class Q protein, playing a role (early) in the biosynthesis of the GPI-anchor. Several genes in the GPI biosynthesis pathway cause multi-system disease with DD/ID and seizures. Flow cytometry has been used in individuals with PIGQ-related disorder. Serum ALP was elevated in some (4) although - as the authors comment - elevations are more typical in disorders affecting later steps of GPI biosynthesis.

More than 10 variants have been reported to date (missense / pLoF).; Changed phenotypes: Epileptic encephalopathy, early infantile, 77, MIM# 618548

Heterozygosity of the variant was also suggested to be associated with spontaneous miscarriage and subfertility. Consanguineous family with 8 total miscarriages from 3 carrier women, and 2 of these were confirmed to be due to hydrops fetalis.
Note: possible association of a variant in ASAH1 gene that is associated with Farber lipogranulomatosis which can sometimes present with antenatal hydrops fetalis. (Homozygosity in one of the fetuses, fetus and heterozygosity in some of the family members).
In vitro biochemical assays indicated that the variant causes misfolding of the protein and reduced association with its chaperone, RAMP2, and reduced translocation to the plasma membrane. (PMID: 30115739; Mackie, DI. et al., 2018).

Review for gene: NARS was set to GREEN
Added comment: [Please note that HGNC Approved Gene Symbol for this gene is NARS1] Manole et al (2020 - PMID: 32738225) provide evidence that both biallelic and monoallelic (de novo) pathogenic NARS1 variants cause a neurodevelopmental disorder. In total 32 individuals from 21 families are reported, with biallelic variants identified in individuals from 13 families and de novo in 8 families. Similar features were reported for AR/AD occurrences of the disorder and included microcephaly (90% - most often primary), epilepsy (23/32 or 74% - variable semiology incl. partial/myoclonic/generalized tonic-clonic seizures), DD and ID (as a universal feature), abnormal tone in several (hypotonia/spasticity), ataxia, demyelinating peripheral neuropathy (in 3 or more for each inheritance mode - or a total of 25%). Some individuals had dysmorphic features. NARS1 encodes an aminoacyl-tRNA synthetase (ARS) [asparaginyl-tRNA synthetase 1]. Aminoacyl-tRNA synthetases constitute a family of enzymes catalyzing attachment of amino-acids to their cognate tRNAs. As the authors comment, mutations in genes encoding several other ARSs result in neurological disorders ranging from peripheral neuropathy to severe multi-systemic NDD. Dominant, recessive or both modes for inheritance for mutations in the same gene (e.g. AARS1, YARS1, MARS1, etc) have been reported. Some variants were recurrent, e.g. the c.1600C>T / p.Arg534* which occurred in 6 families as a de novo event or c.1633C>T p.Arg545Cys (homozygous in 6 families). 3 different variants were reported to have occured de novo (c.965G>T - p.Arg322Leu, c.1525G>A - p.Gly509Ser, p.Arg534*) with several other variants identified in hmz/compound htz individuals. A single SNV (c.1067A>C - p.Asp356Ala) was suggested to be acting as modifier and pathogenic only when in trans with a severe variant. [NM_004539.4 used as RefSeq for all]. The authors provide several lines of evidence for a partial loss-of-function effect (e.g. reduction in mRNA expression, enzyme levels and activity in fibroblasts or iNPCs) underlying pathogenicity of the variants identified in individuals with biallelic variants. A gain-of-function (dominant-negative) effect is proposed for de novo variants (such effect also demonstrated for the p.Arg534* in a zebrafish model).

Review for gene: MAPK1 was set to GREEN
Added comment: Motta et al (2020 - PMID: 32721402) report on 7 unrelated individuals harboring de novo missense MAPK1 pathogenic variants.

The phenotype corresponded to a neurodevelopmental disorder and - as the authors comment - consistently included DD, ID , behavioral problems. Postnatal growth delay was observed in approximately half. Hypertelorism, ptosis, downslant of palpebral fissures, wide nasal bridge as low-set/posteriorly rotated ears were among the facial features observed (each in 3 or more subjects within this cohort). Together with short/webbed neck and abnormalities of skin (lentigines / CAL spots) and growth delay these led to clinical suspicion of Noonan s. or disorder of the same pathway in some. Congenital heart defects (ASD, mitral valve insufficiency, though not cardiomyopathy) occurred in 4/7. Bleeding diathesis and lymphedema were reported only once.

MAPK1 encodes the mitogen-activated protein kinase 1 (also known as ERK2) a serine/threonine kinase of the RAS-RAF-MEK-(MAPK/)ERK pathway.

MAPK1 de novo variants were identified in all individuals following trio exome sequencing (and extensive previous genetic investigations which were non-diagnostic).

The distribution of variants, as well as in silico/vitro/vivo studies suggest a GoF effect (boosted signal through the MAPK cascade. MAPK signaling also upregulated in Noonan syndrome).

Added comment: PMID: 32487539 (2020) - Two affected sibs presenting in early infancy with impaired intestinal peristalsis, intestinal pneumatosis and dysmorphic features. Delayed motor and language development was reported in one sibling, however, the other sibling died at 5 months from cardiac arrest and therefore a psychomotor assessment was performed. Exome sequencing identified a homozygous truncating variant (c.897+3_897+6delAAGT, p.L300Vfs*58) in ANO1 which segregated with disease in the family. Functional data revealed that the variant led to lack of expression of functional TMEM16A in patient cells, which in turn abolished calcium-activated Cl- currents. Also supportive mouse model.

Added comment: Asselin et al (2020 - PMID: 32415109) report on 4 individuals with KIF21B pathogenic variants. DD/ID (borderline intellectual functioning to severe ID) was a feature in all. Variable other findings included brain malformations (CCA) and microcephaly. 3 missense variants and a 4-bp insertion were identified, in 3 cases as de novo events while in a single subject the variant was inherited from the father who was also affected. The authors provide evidence for a role of KIF21B in the regulation of processes involved in cortical development and deleterious effect of the missense variants impeding neuronal migration and kinesin autoinhibition. Phenotypes specific to variants (e.g. CCA or microcephaly) were recapitulated in animal models. Missense variants are thought to exert a gain-of-function effect. As commented on, the 4-bp duplication (/frameshift) variant might not be pathogenic. In blood sample from the respective individual, RT-qPCR analysis suggested that haploinsufficiency (NMD) applies. Although Kif21b haploinsufficiency in mice was shown to lead to impaired neuronal positioning, the gene might partially tolerate LoF variants as also suggested by 28 such variants in gnomAD. Homozygous Kif21b ko mice display severe morphological abnormalities, partial loss of commissural fibers, cognitive deficits and altered synaptic transmission (several refs to previous studies provided by the authors).

Review for gene: TBC1D2B was set to GREEN
Added comment: Harms et al (2020 - PMID: 32623794) report on 3 unrelated individuals with biallelic pLoF TBC1D2B variants. Features included cognitive impairment (mild ID in one case, regression at the age of 12y in another, hypotonia and delayed milestones in a third aged 8m), seizures (3/3 - variable age of onset) and/or gingival overgrowth (2/3 - prior to initiation of AEDs). Other findings included behavioral abnormalities, mandibular anomalies, abnormal brain imaging and ophthalmologic or (rarely) audiometric evaluations. All were born to non-consanguineous couples and additional investigations were performed in some. Variants were identified by WES or trio WGS, with Sanger confirmation/compatible segregation analyses. In line with the pLoF variants, mRNA studies in fibroblasts from 2 unrelated affected individuals demonstrated significantly reduced (~80-90%) TBC1C2D mRNA levels compared to controls, restored following cycloheximide treatment. Protein was absent in patient fibroblasts. TBC-domain containing GTPase activating proteins are known as key regulators of RAB GTPase activity. TBC1D2B was shown to colocalize with RAB5-positive endocytic vesicles. CRISPR/Cas9-mediated ko of TBC1D2B in HeLa cells suggested a role in EGF receptor endocytosis and decreased cell viability of TBC1D2B-deficient HeLa cells upon serum deprivation. Genes encoding other TBC domain-containg GTPase-activating proteins, e.g. TBC1D7 and TBC1D20, TBC1D24 are associated with recessive neurodevelopmental disorders (with ID and/or seizures) and the pathophysiological defect in TBC1D2B-related disorder (deficit in vesicle trafficking and/or cell survival) is proposed to be similar to that of TBC1D24.

Review for gene: EXOC2 was set to AMBER
Added comment: Van Bergen et al (2020 - PMID: 32639540) report on 3 individuals from 2 families, harboring biallelic EXOC2 mutations. Clinical presentation included DD, ID (severe in 2 subjects from fam1, borderline intellectual functioning in fam2), dysmorphic features and brain abnormalities. Cerebellar anomalies were common to all with a molar tooth sign observed in one (1/3). Other findings limited to subjects from one family included acquired microcephaly, congenital contractures, spastic quadriplegia (each observed 2/3). Previous investigations were in all cases non-diagnostic. WES identified biallelic EXOC2 mutations in all affected individuals. EXOC2 encodes an exocyst subunit. The latter is an octameric complex, component of the membrane transport machinery, required for tethering and fusion of vesicles at the plasma membrane. As discussed ,vesicle transport is important for the development of brain and the function of neurons and glia. Exocyst function is also important for delivery of Arl13b to the primary cilium (biallelic ARL13B mutations cause Joubert syndrome 8) and ciliogenesis. Affected subjects from a broader consanguineous family (fam1) were homozygous for a truncating variant. Fibroblast studies revealed mRNA levels compatible with NMD (further restored in presence of CHX) as well as reduced protein levels. The female belonging to the second non-consanguineous family was found to harbor 2 missense variants in trans configuration. An exocytosis defect was demonstrated in fibroblasts from individuals belonging to both families. Ciliogenesis appeared to be normal, however Arl13b localization/recruitment to the cilia was reduced compared with control cells with the defect rescued upon exogenous expression of wt EXOC2. Mutations in other genes encoding components of the exocyst complex have been previously reported in individuals with relevant phenotypes (e.g. EXOC8 in a boy with features of Joubert s. or EXOC4 in nephrotic syndrome). The authors discuss on the essential role of EXOC2 based on model organism studies (e.g. impaired neuronal membrane traffic, failure of neuronal polarization and neuromuscular junction expansion seen in Drosophila Sec5 (EXOC2) null mutants).

Added comment: Biallelic pathogenic CCDC174 variants cause Hypotonia, infantile, with psychomotor retardation - IHPMR (MIM 616816). Volodarsky et al [2015 - PMID: 26358778] describe 6 children from 2 unrelated families with - among others - severe hypotonia, psychomotor delay and abducens nerve palsy. All affected subjects were homozygous for a stoploss variant. Evidence from functional studies/animal model is provided supporting the role of the gene in this phenotype.

Added comment: Biallelic pathogenic ABCA2 variants cause Intellectual developmental disorder with poor growth and with or without seizures or ataxia (MIM 618808). There are 3 relevant publications (01-07-2020) : - Maddirevula et al [2019 - PMID: 30237576] described briefly 2 unrelated subjects (16-2987, 16DG0071) both DD and seizures among other manifestations. - Hu et al [2019 - PMID: 29302074] reported 3 sibs (M8600615 - III:1-3) born to consanguineous parents (M8600615 - III:1-3) with DD/ID (formal confirmation of moderate ID, in those (2) evaluated). One also presented with seizures. - Aslam and Naz [2019 - PMID: 31047799] provided clinical details on 2 siblings born to consanguineous parents. ID was reported for the older sib but was absent in the younger one. Seizures were not part of the phenotype. All subjects harbored biallelic pLoF variants. N.B. : Steinberg et al [2015 - PMID: 25773295], within a cohort of patients with ALS, identified one with biallelic ABCA2 variants. As however Aslam and Naz comment, this person harbored a single pathogenic variant, with a second one rather unlikely to be pathogenic due to high allele frequency. Overall this gene can be considered for inclusion with green rating in both ID and epilepsy panels (each in >=3 unrelated individuals).

Added comment: 4 families with 8 affected individuals with brain atrophy, seizures, and developmental delay, and in more severe cases microcephaly and infantile death. Four novel homozygous or comp.heterozygous variants found in EXOC7, which segregated with disease in the families. They showed that EXOC7, a member of the mammalian exocyst complex, is highly expressed in developing human cortex. In addition, a zebrafish model of Exoc7 deficiency recapitulates the human disorder with increased apoptosis and decreased progenitor cells during telencephalon development, suggesting that the brain atrophy in human cases reflects neuronal degeneration.

Added comment: Axl null mice had delayed first oestrus and persistently abnormal oestrous cyclicality compared with wild-type controls. Only a single study reported screening human cases. In a screen of 104 probands with KS or nIHH, four heterozygous AXL mutations were identified in two KS and two nIHH unrelated subjects (two males and two females). Three of the variants appear to be too common in gnomAD v2.1 given the reported prevalence of KS reported in GeneReviews (1:30,000 in males and 1:125,000 in females): c.587-6C>T (normal splicing in RNA studies, NFE AF 0.0001472), p.Q361P (NFE 0.002560), p.L50F (AJ 0.004405). The other variant p.S202C (4 hets, 1 female in gnomAD v2.1) is rare enough in gnomAD for a dominant disorder. In vitro functional assays were conducted and p.S202C had an significant effect on function, but so did the more common variant p.Q361P.

Functional analysis of patient‐ and control‐derived keratinocytes revealed a deleterious effect of the identified variant on the intracellular localization of PERP. A previous report showed that PERP mutation causes a dominant form of keratoderma but a single patient in that report with a homozygous variant in PERP suggests that recessive inheritance is also possible.

Added comment: One patient with severe global developmental delay, language impairment and epileptic encephalopathy. Homozygous OTUD7A missense variant (c.697C>T, p.Leu233Phe), predicted to alter an ultraconserved amino acid, lying within the OTU catalytic domain. Its subsequent segregation analysis revealed that the parents, presenting with learning disability, and brother were heterozygous carriers. Biochemical assays demonstrated that proteasome complex formation and function were significantly reduced in patient‐derived fibroblasts and in OTUD7A knockout HAP1 cell line. Gene lies in the chromosome 15q13.3 region. Heterozygous microdeletions of chromosome 15q13.3 show incomplete penetrance and are associated with a highly variable phenotype that may include intellectual disability, epilepsy, facial dysmorphism and digit anomalies.

Publications for gene: UGDH were set to 32001716
Phenotypes for gene: UGDH were set to Epileptic encephalopathy, early infantile, 84 - MIM #618792
Review for gene: UGDH was set to GREEN
Added comment: 36 individuals with biallelic UGDH pathogenic variants reported. The phenotype corresponded overall to a developmental epileptic encephalopathy with hypotonia, feeding difficulties, severe global DD, moderate or commonly severe ID in all. Hypotonia and motor disorder (incl. spasticity, dystonia, ataxia, chorea, etc) often occurred prior to the onset of seizures. A single individual did not present seizures and 2 sibs had only seizures in the setting of fever. There were no individuals with biallelic pLoF variants identified. Parental/sib studies were all compatible with AR inheritance mode.

UGDH encodes the enzyme UDP-glucose dehydrogenase which converts UDP-glucose to UDP-glucuronate, the latter being a critical component of the glycosaminoglycans, hyaluronan, chondroitin sulfate, and heparan sulfate. Patient fibroblast and biochemical assays suggested a LoF effect of variants leading to impairment of UGDH stability, oligomerization or enzymatic activity (decreased UGDH-catalyzed reduction of NAD+ to NADH / hyaluronic acid production which requires UDP-glucuronate).

Attempts to model the disorder using an already developped zebrafish model (for a hypomorphic LoF allele) were unsuccessful as fish did not exhibit seizures spontaneously or upon induction with PTZ. Modelling of the disorder in vitro using patient-derived cerebral organoids demonstrated smaller organoids due to reduced number of proliferating neural progenitors

Review for gene: YIF1B was set to GREEN
Added comment: 6 individuals (from 5 families) with biallelic YIF1B truncating variants reported. Presenting features: hypotonia, failure to thrive, microcephaly (5/6), severe global DD and ID as well as features suggestive of a motor disorder (dystonia/spasticity/dyskinesia). Seizures were reported in 2 unrelated individuals (2/6). MRI abnormalities were observed in some with thin CC being a feature in 3. Affected individuals were found to be homozygous for truncating variants (4/5 families being consanguineous). The following 3 variants were identified (NM_001039672.2) : c.186dupT or p.Ala64fs / c.360_361insACAT or p.Gly121fs / c.598G>T or p.Glu200*. Yif1B KO mice demonstrate a disorganized Golgi architecture in pyramidal hippocampal neurons (Alterio et al 2015 - PMID: 26077767). Functional/network analysis of genes co-regulated with YIF1B based on available RNAseq data, suggest enrichement in in genes important for nervous system development and function.

Added comment: Homozygous and compound heterozygous variants (missense, nonsense and frameshift) found in 8 Japanese patients from unrelated families with unexplained galactosaemia. (No variants in GALT, GALK1, and GALE). This is therefore type IV galactosaemia.
In vitro expression analysis and enzyme activity assay of the patients’ peripheral blood mononuclear cells showed total lack of or compromised expression of GALM protein. Loss-of-function mechanism. One homozygote for one of these variants p.(Gly142Arg) in gnomAD (African population). (Wada, Y. et al 2019; PMID: 30451973)
In vitro expression assay and an enzyme activity assay of 67 GALM variants, taken from ExAc database (missense, nonsense, frameshift and splice). 30 variants concluded to be pathogenic due to no protein expression or faint expression. 5 variants with mildly lower levels were determined as likely pathogenic. All concluded to be loss-of-function mechanism. Incidence of galactosaemia by GALM deficiency is comparable to that of other galactosaemias. Carrier frequency and incidence was estimated for different populations. (Iwasawa, S. et al. (2019); PMID: 30910422)

Added comment: Homozygous missense, NM_001452.1: c.325A>T (p.I109F), in a 10 year old girl (consanguineous, parents were first cousins) with profound sensorineural hearing loss (SNHL) associated with incomplete partition type I anomaly of the cochlea. This variant is absent in the gnomAD v2.1.1. In vitro studies indicated instability, shorter half-life of the protein compared to wildtype. Embryonic knockout mouse showed shortened and malformed cochleae, in addition to altered shape of hair cells with innervation and planar cell polarity defects. Homozygous knockout mice do not survive. (Bademci, G. et al. (2019); PMID: 30561639).
This gene has also been reported in association with other anomalies including cleft lip, cleft palate, brain anomalies, intestine anomalies, and eye anomalies. Eye anomalies include anterior segment dysgenesis, as shown in mice with variant, W174R, affecting the Fox domain. Homozygote mice do not survive. (McKeone, R. et al. (2011); PMID: 22022403).

Added comment: 2 unrelated Chinese families reported with rare homozygous variants (one missense, one nonsense) and Leber congenital amaurosis. Animal knockout functional studies supported gene-disease association.

PMID: 30573563 "By analysing WES data based on allele frequencies of in-house controls, population allele frequencies and in silico prediction tools, two rare homozygous mutations in USP45 were identified in two unrelated families. Immunohistochemistry of USP45 in the human and zebrafish retinal sections revealed enriched expression in the inner segments of photoreceptors. The knockdown of usp45 transcript in zebrafish led to abnormal retinal development with effects on photoreceptors, which could be successfully rescued by wild-type usp45 mRNA. Moreover, targeted knockout of Usp45 in mice caused abnormal electroretinography responses, similar to that seen in patients with LCA."

Added comment: A consanguineous German family segregating a homozygous nonsense mutation in two sisters with congenital cataracts (PMID: 25804400). Null Zebrafish, Xenopus and mouse models recapitulate the human cataract phenotype. A case with congenital cataracts as a feature of their condition harboured a de novo balanced chromosomal translocation, 46,XY,t(2;19)(q37.3;q13.1), where breakpoint mapping and sequencing showed a physical disruption of the 5′UTR of SIPA1L3 (PMID: 26231217). In a case with bilateral congenital cataracts a heterozygous missense (D148Y) was identified and in vitro functional assays of the variant resulted in abnormal actin morphology (PMID: 26231217).
