Review for gene: PRMT9 was set to RED
Added comment: A homozygous variant (G189R) in PRMT9 is reported based on large WGS study in 136 consanguineous families - unclear if only found in 1 family and no clinical information on case(s).

PMRTs (protein arginine methyltransferases) catalyse post translational modification via arginine methylation. Functional studies showed that the G189R variant abolishes PRMT9's methyltransferase activity - specifically at the R508 residue of SF3B2 RNA (exclusively methylated by PRMT9) - and leads to heavy PRMT9 ubiquitination, and abnormal splicing activity of SF3B2. Knock out mouse model showed PRMT9 loss in excitatory neurons leads to aberrant synapse development and impaired learning and memory.

Added comment: 8 individuals from 6 families with core features of amelogenesis imperfecta and sensorineural hearing loss. Intellectual disability, ocular disease, ear developmental abnormalities and lymphoedema were also present in multiple cases. WES and WGS identified biallelic pathogenic variants in PLXNB2 (missense, nonsense, splice and a multiexon deletion variants). Variants segregated with disease.

PLXNB2 is a large transmembrane semaphorin receptor protein, and semaphorin-plexin signalling controls cellular interactions that are critical during development as well as in adult life stages. Plxnb2 expression was detected in differentiating ameloblasts in mice. Human phenotype overlaps with that seen in Plxnb2 knockout mice.

Added comment: 4 children from 2 unrelated families with Seckel-like syndrome - severe primary microcephaly, short stature, developmental delay, intellectual disability, facial deformities, and abnormalities of fingers and toes. WES identified biallelic pathogenic variants in CEP295 gene (p(Q544∗) and p(R1520∗); p(R55Efs∗49) and p(P562L)).

Patient-derived fibroblasts and CEP295-depleted U2OS and RPE1 cells were used to clarify the underlying mechanisms. Depletion of CEP295 resulted in a decrease in the numbers of centrioles and centrosomes and triggered p53-dependent G1 cell cycle arrest. Loss of CEP295 caused extensive primary ciliary defects in both patient-derived fibroblasts and RPE1 cells. The results from complementary experiments revealed that the wild-type CEP295, but not the mutant protein, can correct the developmental defects of the centrosome/centriole and cilia in the patient-derived skin fibroblasts.

Added comment: AMBER rating as two of the families had affected fetuses, one had a severely affected newborn, and fourth had a progressive course: none fit well with ID, though there's likely to be a continuum.

PMID 35066879: 3 fetuses from 2 different branches of a consanguineous family, presenting with distal arthrogryposis, underdevelopment of the corpus callosum, and dysmorphic facial features. Exome sequencing identified a biallelic 4-bp deletion (c.233_236delTTCC; p.Leu78Glnfs*11) in USP14, and sequencing of family members showed segregation with the phenotype. Ubiquitin-specific protease 14 (USP14) encodes a major proteasome-associated deubiquitinating enzyme with an established dual role as an inhibitor and an activator of proteolysis, maintaining protein homeostasis. Usp14-deficient mice show a phenotype similar to lethal human multiple congenital contractures phenotypes, with callosal anomalies, muscle wasting, and early lethality, attributed to neuromuscular junction defects due to decreased monomeric ubiquitin pool. RT-qPCR experiment in an unaffected heterozygote revealed that mutant USP14 was expressed, indicating that abnormal transcript escapes nonsense-mediated mRNA decay.

PMID 38469793: biallelic USP14 variants in four individuals from three unrelated families: one fetus, a newborn with a syndromic NDD, and two siblings affected by a progressive neurological disease. Specifically, the two siblings from the latter family carried two compound heterozygous variants c.8T>C p.(Leu3Pro) and c.988C>T p.(Arg330*), while the fetus had a homozygous frameshift c.899_902del p.(Lys300Serfs*24) variant and the newborn patient harbored a homozygous frameshift c.233_236del p.(Leu78Glnfs*11) variant. The fetus and the newborn had extensive brain malformations.

- Nine individuals from six families presenting with a spectrum of neurodevelopmental/neurodegenerative features caused by bi-allelic variants in SNF8. In total, three putative LoF variants and four missense variants were identified.
- The phenotypic spectrum included four individuals with severe developmental and epileptic encephalopathy, massive reduction of white matter, hypo-/aplasia of the corpus callosum, neurodevelopmental arrest, and early death. A second cohort shows a milder phenotype with intellectual disability, childhood-onset optic atrophy, or ataxia. All mildly affected individuals shared the same hypomorphic variant, c.304G>A (p.Val102Ile) as compound heterozygous.
- Functional studies using fibroblasts derived from patients and zebrafish model showed LoF is the disease mech.

Overlapping deletions in publicly reported databases examined, and RREB1 postulated to be the key gene. Rreb1 hemizygous mice display orbital hypertelorism and age dependent cardiac hypertrophy. 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.

Phenotypes for gene: ZFX were set to X-linked neurodevelopmental disorder with recurrent facial gestalt
Review for gene: ZFX was set to GREEN
Added comment: To date, germline variants in ZFX have not been associated with a phenotype in OMIM or Gen2Phen.
A single ZFX variant has been associated with a neurodevelopmental disorder, that has a Rett syndrome-like phenotype disorder, in a 14 year old male. The ZFX variant was allelic with another X-linked variant in SHROOM4. These variants were inherited from the mother, who had random X inactivation pattern (PMID: 26740508).
PMID: 38325380 reports 11 ZFX variants in 18 subjects from 16 unrelated families (14 males and 4 females) with an X-linked neurodevelopmental disorder with recurrent facial gestalt. Seven variants were truncating and the remaining were missense variants within the Zinc finger array. In the pedigree of family 6 (figure 3, PMID: 38325380), it was apparent that there were female carriers of the ZFX variant (GRCh38 chrX: 24229396A>G, c.2438A>G, p.Tyr774Cys) with hyperparathyroidism and two affected males and one affected female, with the neurodevelopmental disorder. It appeared that skewed X-inactivation in the female carriers was responsible for the different phenotypic features. The association between ZFX variants and a novel neurodevelopmental disorder, was further supported by functional studies showing altered transcriptional activity in missense variants and altered behavior in a zebrafish loss-of-function model.

Added comment: 11 male patients with 6 missense and 1 nonsense variant in WDR44 displaying a wide range of cognitive impairment and variable congenital anomalies associated with primary cilium dysfunction. All patients had learning difficulties with 8 labelled as intellectually disabled (mild-moderate). Other clinical features included anomalies of craniofacial, musculoskeletal, brain, renal and cardiac development.
WDR44 is a negative regulator of ciliogenesis. Increased binding is hypothesised to underlie the pathogenicity of WDR44 variants identified in this cohort. Functional data supported impaired ciliogenesis initiation in patient fibroblasts and a zebrafish model. A zebrafish model recapitulated the human phenotype when morphants expressed WDR44 L668S, D669N, S764F, G782C, H839R, and R733* variants. Of note, D648G or N840S did not recapitulate the phenotype in the zebrafish model.
The studies supported a GoF mechanism, but the authors could not rule out that LoF of WDR44 contributes to the ciliopathy-like phenotype observed, because protein expression data was only available for a limited number of patients.

Added comment: PMID: 38288683: reported 5 unrelated patients with de novo heterozygous variants (missense and PTV) in SP9 gene. In silico and in vitro studies suggested a novel form of interneuronopathy with variable severity depending on the presence of loss or gain of function variants. Patients with loss-of-function variants had ID, ASD, and epilepsy, whereas missense variants in the second C2H2 binding domain result in hypomorphic and neomorphic DNA binding functions that cause severe epileptic encephalopathy. The author suggested a novel form of interneuronopathy with variable severity depending on the presence of loss or gain of function variants.

Added comment: Three individuals who each share a recurrent de novo germline variant in the MAX gene, resulting in a p.Arg60Gln substitution in the loop of the b-HLH-LZ domain.

Affected individuals have a complex disorder consisting primarily of macrocephaly, polydactyly, and delayed ophthalmic development. Other phenotypes reported include intellectual disability, perianal abscesses, pectus carinatum, hypospadias, renal agenesis, single umbilical artery, flattened thoracic vertebrae.

Functional analysis of the p.Arg60Gln variant shows a significant increase in CCND2 protein and a more efficient heterodimerization with c-Myc resulting in an increase in transcriptional activity of c-Myc.

HEK293T cells show the missense variants are expressed at normal levels but exhibit reduced assembly with other BORC subunits and reduced ability to drive lysosome distribution. The BORCS8 PTC frameshift variant is expressed at lower levels and is completely incapable of assembling with other BORC subunits and promoting lysosome distribution. Zebrafish KO of the orthologous brocs8 causes decreased brain and eye size, neuromuscular anomalies and impaired locomotion, recapitulating some of the key traits of the human disease.

Intellectual disability syndromic and non-syndromic v0.5660 SOX8 Paul De Fazio changed review comment from: Proband presented to genetics clinic at 27 years of age with BMI -3.4SD, height -2.7SD, head circumference -1.8SD. She had mild intellectual delay and clinical features of a congenital, nonprogressive myopathy with moderate proximal and distal weakness. X-rays showed skeletal dysplasia, including cervical thoracic scoliosis and lumbar scoliosis. She was reported as having had weakness at birth with poor suck, micrognathia, hypotonia, and talipes. She was documented to have significant motor delay as a child. MRI of the brain demonstrated large posterior fossa CSF spaces.

Biallelic SOX8 variants biallelic (NM_014587.3:c.422+5G>C; c.583dup p.(His195ProfsTer11)) were identified by WGS. The +5 variant was shown to affect splicing, while the frameshift variant resulted in production of low-level truncated protein (not NMD predicted).

Added comment: PMID: 38158856 - Six affected individuals from four unrelated families with homozygous CACHD1 variants (3 splice, 2 frameshift and 1 nonsense variant). Excluding the two fatal cases, all other were affected by syndromic neurodevelopmental abnormalities, multiple organ systems featuring global impairment of psychomotor development, dysmorphic facial features, genitourinary abnormalities, oculo-auricular and congenital malformation. Seizure was reported in one case. Whole exome sequencing identified bi-allelic loss of function variants in the CACHD1 gene. In vitro human neural models of CACHD1 depletion displayed dysregulated of Wnt signaling in the developing brain.

Added comment: Proband presented to genetics clinic at 27 years of age with BMI -3.4SD, height -2.7SD, head circumference -1.8SD. She had mild intellectual delay and clinical features of a congenital, nonprogressive myopathy with moderate proximal and distal weakness. X-rays showed skeletal dysplasia, including cervical thoracic scoliosis and lumbar scoliosis. She was reported as having had weakness at birth with poor suck, micrognathia, hypotonia, and talipes. She was documented to have significant motor delay as a child. MRI of the brain demonstrated large posterior fossa CSF spaces.

Biallelic SOX8 variants biallelic (NM_014587.3:c.422+5G>C; c.583dup p.(His195ProfsTer11)) were identified by WGS. The +5 variant was shown to affect splicing, while the frameshift variant resulted in production of low-level truncated protein (not NMD predicted).

Added comment: 3 unrelated families with five affected children with homozygous or compound heterozygous loss of function missense and PTC variants.

HEK293T cells show the missense variants are expressed at normal levels but exhibit reduced assembly with other BORC subunits and reduced ability to drive lysosome distribution. The BORCS8 PTC frameshift variant is expressed at lower levels and is completely incapable of assembling with other BORC subunits and promoting lysosome distribution. Zebrafish KO of the orthologous brocs8 causes decreased brain and eye size, neuromuscular anomalies and impaired locomotion, recapitulating some of the key traits of the human disease.

Added comment: PMID: 38118446- Cohort of individuals with variants in GTPBP2 (which has been previously described) and GTPBP1 (new) who have an identical neurodevelopmental syndrome. 4 homozygous individuals from 3 consanguineous families. 2 families have different NMD-predicted nonsense variants and the third has a missense, all are absent from gnomad v4.

The shared cardinal features of GTPBP1 and 2 related disease are microcephaly, profound neurodevelopmental impairment, and distinctive craniofacial features. Epilepsy was present in 10 of 20 individuals but its not clear if those individuals had GTPBP1 or 2 variants.

Null mouse and patient derived white adipose tissue showed enrichment of arachidonic acid-containing membrane phospholipids and a strong decrease in PPARγ. CRISPR–Cas9-mediated PLAAT3 inactivation in human adipose stem cells induced insulin resistance, altered adipocyte differentiation with decreased lipid droplet formation and reduced the expression of adipogenic and mature adipocyte markers, including PPARγ.

11 patients with het de novo variants in DDX17 (5 NMD, 6 missense). Patient's phenotype included mild-moderate intellectual disability, delayed speech and language development and global developmental delay. 64% had dysmorphic facial features. Some patients also have gross and fine motor delay, generalized hypotonia, stereotypy, and evidence of autism spectrum disorder.

Knockdown of Ddx17 in newborn mice showed impaired axon outgrowth and reduced axon outgrowth and branching was observed in primary cortical neurons in vitro. This result was replicated in Crispant Xenopus tadpoles, which had clear functional neural defects and showed an impaired neurobehavioral phenotype.

Added comment: Missense variant, c.604T>C; p.Phe202Leu, identified in two siblings with childhood-onset neurodevelopmental disorder characterised by global developmental delay, intellectual disability, behavioural abnormalities, and dysmorphic features. The variant is located in the catalytic domain of the kinase, and is inherited from unaffected mosaic mother.

Functional investigation revealed that the variant results in a gain-of-function in the ability of MARK4 to phosphorylate tau and leads to up-regulation of the mTORC1 pathway.

SEL1L protein is involved in the SEL1L-HRD1 endoplasmic reticulum (ER)-associated degradation.

Report two biallelic missense variants in SEL1L in six children from three independent families presenting with developmental delay, intellectual disability, microcephaly, facial dysmorphisms, hypotonia and/or ataxia (termed ERAD-associated neurodevelopment disorder with onset in infancy (ENDI). The variants were hypomorphic and impaired ERAD function.

Identified by WES. Parents heterozygous and asymptomatic. P.(Gly585Asp) in Patient 1, p.(Met528Arg) in Patients 2 and 3 (siblings).

All variants cause substrate accumulation. The extent of substrate accumulation in knockin cells was modest compared to those in knockout cells, pointing to a hypomorphic nature.

They also had a variant in HRD1.



Weis paper PMID: 37943617

Third variant p.(Cys141Tyr), biallelic, causing premature death in five patients from a consanguineous family with early-onset neurodevelopmental disorders and agammaglobulinaemia due to severe SEL1L-HRD1 ERAD dysfunction.

This variant appears to have a more severe outcome, exhibiting B cell depletion and agammaglobulinaemia, causing the most severe dysfunction among all of the variants described by this group so far. They postulate that functionality of SEL1L-HRD1 ERAD is inversely correlated with disease severity in humans.

Their symptoms were dev delay, neurological disorder and agammaglobulinaemia in childhood. Along with severe axial hypotonia, short stature and microcephaly.

“Not a complete loss-of-function variant”.

- 13 patients from 8 families of Ashkenazi Jewish origin all had the same homozygous frameshift variant (c.981dup). Predicted to cause NMD. The variant co-segregated with disease in all available family members. The affected individuals displayed mild global developmental delay and mild to moderate intellectual disability. Additional prevalent phenotypes observed included hypotonia, behavioural challenges and short stature. Considered a founder variant (1 in 52 Ashkenazi Jews carry the variant). Also present in other populations but no homozygotes in gnomAD.

Added comment: “A novel ELP1 mutation impairs the function of the Elongator complex and causes a severe neurodevelopment disorder”.

The Elongator complex is suggested to play a role in NDDs, given that patient-derived mutations in its ELP2, ELP3, ELP4 and ELP6 subunits have been associated with these disorders.

Pathogenic variants in ELP1 have been previously found in familial dysautonomia and medulloblastoma, with no link to NDDs affecting primarily the central nervous system.

Clinical investigation included patient history and physical, neurological and MRI. A novel homozygous likely pathogenic ELP1 variant was identified by WGS (absent from gnomAD). Functional studies included in silico analysis of the mutated ELP1 in the context of the holo-complex, production and purification of the ELP1 harbouring the identified mutation and in vitro analyses.

Report a novel missense mutation in the ELP1 identified in two siblings with ID and GDD (both less than 10 years old). The mutation is shown to perturb the ability of ELP123 to bind tRNAs and compromises the function of the Elongator in vitro and in human cells.

Both sibling are non-verbal and had severe ID/GDD. MRI revealed white matter lesions with enlarged perivascular spaces, suggestive of an inflammatory reaction associate with demyelination. WGS identified c.2444A>C; p.(Lys815Thr), homozygous in both siblings. Consanguineous family. Parents heterozygous and asymptomatic. Carry out significant functional studies.

Conclude that screening for ELP1 mutations “may be beneficial”.

Presentations included (mild) ID and/or behavioural problems, postnatal growth retardation, feeding difficulties, dysmorphism (rarely cleft palate). Nuclear abundance of ZFHX3 increases during human brain development and neuronal differentiation in neural stem cells and SH-SY5Y cells, ZFHX3 interacts with the chromatin remodelling BRG1/Brm-associated factor complex and the cleavage and polyadenylation complex. ZFHX3 haploinsufficiency associates with a specific DNA methylation profile in leukocyte-derived DNA, and participates in chromatin remodelling and mRNA processing.; Changed rating: GREEN; Changed publications: PMID: 37292950; Changed phenotypes: Neurodevelopmental disorder; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted; Set current diagnostic: yes

Cohort patients with an MRI based diagnosis of megalencephalic leukoencephalopathy with subcortical cysts (MLC). Missense variant in AQP4 seen homozygous in 2 siblings and het in the parents. Patients had macrocephaly, developmental delay, hypotonia, epilepsy, and cognitive deficit.

Western blots on generated MDCK cell lines showed no detectable expression of AQP4 protein from the cells with the patients variant. Immunofluorescence also showed no membrane expression. Overexpression studies in HEK293T cells showed WT was seen as mainly monomers or dimers where as variant protein formed large aggregates- likely due to the saturation of protein degradation pathways because of the overexpression.

Added comment: PMID: 37143309
Cohort of 5 patients with an MRI based diagnosis of megalencephalic leukoencephalopathy with subcortical cysts (MLC). 3 unrelated patients had variants in GPRC5B, 2 have the same inframe dup Ile175dup and the third has an in frame dup of Ala177. All 3 were de novo and unaffected siblings did not have the variants. All patients have macrocephaly, delayed motor development, spasticity, ataxia and dystonia, seizures, all had varying degrees of cognitive deficits. MRI showed MLC, abnormal and swollen cerebral white matter.

Patient cell lines showed reduced regulatory volume decrease, and western blot showed a strong increase in GRPC5B levels in patient lymphoblasts. Together, these findings indicate disturbed volume regulation in lymphoblasts from patients with GPRC5B variants, potentially due to increased GPRC5B levels. Transfected cells caused increased volume-regulated anion channel activity.

Added comment: Report a de novo heterozygous NAA30 nonsense variant c.244C>T, p.(Gln82*) in a 5yo boy with GDD, ASD, hypotonia, seizures, tracheal cleft and recurrent respiratory infections. Seizures resolved after two weeks of life. Family history of ASD in older sister. Epilepsy in mother, childhood onset.

Biochemical studies performed to assess the functional impact of the premature stop codon on catalytic activity. The variant was found to completely disrupt N-terminal acetyltransferase activity using an in vitro acetylation assay.

Variant de novo, “in a gene sensitive to loss of heterozygosity”. Limitation of study - have not established whether this gene variant acts in a dominant or recessive manner.

Added comment: 17 unrelated individuals with severe early-onset developmental and epileptic encephalopathy (DEE), intellectual disability, and severe motor and cortical visual impairment were identified with ten distinct heterozygous variants inTMEM63B. The variants occurred de novo in 16/17 individuals for whom parental DNA was available and either missense or in-frame. All individuals had global developmental delay, with moderate-to-profound intellectual disability and severe motor impairment. All individuals had early-onset drug-resistant epilepsy, whose onset ranged from birth to 3 years but occurred within the first year in 14/17 (82%) and in the first month of life in 6/17 (35%).

Added comment: 2 families with 4 affected individuals with Oral-facial-digital (OFD) phenotype. Homozygosity mapping and WES found 2 homozygous variants in INTS13 gene. This is a subunit of the Integrator complex, which associates with RNA Polymerase II and cleaves nascent RNA to modulate gene expression. Variants segregated with disease. Depletion of INTS13 disrupts ciliogenesis in human cultured cells and causes dysregulation of a broad collection of ciliary genes. Knockdown in Xenopus embryos leads to motile cilia anomalies.

3 unrelated cases with CdLS (1 x TOP with MCA, 1 x death @20mths, 1 x living child)
Features suggestive of CdLS - DD, microcephaly, CHD, dysmorphism, visual/hearing impairment.

WES identified recurrent de novo variant (p.Ser470Phe) in DCAF15 gene. This mediates ubiquitination and degradation of target proteins, and interacts with cohesin complex members (SMC1/SMC3).

Protein analysis from individuals showed increased accumulation of ubiquitination-modified proteins and SM3 (GOF mechanism). EpiSign analysis showed same DNA methylation pattern as other CdLS cases/genes. Zebrafish model showed reduced body length, reduced head size, reduced oligodendrocytes, heart defect, aberrant motor neurons, and abnormal response to visual/auditory stimuli.

Added comment: PMID: 37352860 - 8 individuals from 7 unrelated families
- Patients with biallelic missense show a MORE severe spondyloepimetaphyseal dysplasia, syndactyly, brachydactyly/clinodactyly/camptodactyly
- Patients with biallelic null/whole gene deletion had mild ID and digit anomalies including brachydactyly/clinodactyly/camptodactyly
- Patient chet for a missense and PTC variant has a blended phenotype with short stature, syndactyly, brachydactyly/clinodactyly/camptodactyly, mild ID and failure to thrive

- Missense variants were functionally shown to not be able to rescue 5.8S rRNA processing in KO HeLa cells
- K/O mice had neonatal lethality with growth defects, brachydactyly. Skeletal-specific K/O had mild platyspondyly, had more in keeping with patients with null variants than missense

More severe phenotype hypothesised due to "exonuclease-dead proteins may compete for the target RNA molecules with other exonucleases that have functional redundancy
with ERI1, staying bound to those RNA molecules"

Added comment: PMID: 37403762- 6 patients with RPH3A variant. All 6 have ID, 4 have epilepsy, 2 with obesity, 1 with dysmorphic features. All 6 have missense variants, 3 shown to be de novo, the other 3 parents were not available for testing. I patient also had language and motor impairment, breathing issues and mixed hypo/hypertonia- he also had variants in CUL4B, PRKAG2, SCN4A, none of these genes cause seizures (which he had).

Patch clamp studies on 2 of the missense showed they increased either the number of NMDA receptors on neuron membrane surface or increased their conductance. Study suggests that the variants interrupt the normal role of RPH3A activity at the synaptic NMDAR complex which is needed for the induction of synaptic plasticity and NMDAR-dependant behaviours

Also previously 1 biallelic patient was reported, PMID: 29441694- 1 girl with learning disabilities, tremors, ataxia, hyperglycemia and muscle fatigability. Chet for 2 RPH3A missense. Functional analysis showed strong and marginal impairment of protein binding for each variant.

Added comment: PMID:37183800 Bayat et al 2023 report 6 unrelated patients with heterozygous NMD-predicted LoF variants in UNC79 - x1 canonical splice site variant, x5 nonsense/frameshift. 5 were confirmed de novo, 1 not identified in mother - father unavailable for testing. All variants absent in gnomAD and v2 pLI score for UNC79 is 1.

Patients with UNC79 variants were identified through GeneMatcher or an international network of Epilepsy and Genetics departments. x1 patient underwent duo exome sequencing, remaining had trio exome sequencing - no other causative variants identified.

Phenotypic features included:
- 4/6 autistic features
- 5/6 patients mild-moderate ID
- 4/6 behavioural issues (aggression, stereotypies)
- 4/6 epilepsy (focal to bilateral tonic-clonic seizures)
- 5/6 hypotonia

unc79 knockdown drosophila flies exhibited significantly higher rate of seizure-like behaviour than controls. unc79 haploinsufficiency shown to lead to significant reduction in protein levels of both unc79 and unc80 in mouse brains. Unc79 haploinsufficiency associated with deficiency in hippocampal-dependent learning and memory in mice.

Authors have reviewed their own evidence in relation to the gene-disease criteria detailed by Strande et al 2017 and note that their clinical and experimental data provides moderate-level evidence supporting the association between UNC79 and a neurodevelopment disorder including ASD.

Amber association favoured due to clinical phenotypic range reported between affected individuals and their lack of specificity.

Added comment: We associate ultra-rare variants in POU3F2, encoding a central nervous system transcription factor, with syndromic obesity and neurodevelopment delay in 12 individuals. Demonstrate variant pathogenicity through in vitro analysis. Used exome sequencing, GeneMatcher and Genomics England 100,000 Genomes Project rare disease database.

Both truncating and missense variants in over 10 individuals sharing autism spectrum disorder, NDD, and adolescent-onset obesity (may have had other features eg. CAKUT in 2 individuals, diabetes in two) . Affected individuals presented with low-to-normal birth weight and infantile feeding difficulties but developed insulin resistance and hyperplasia during childhood. With the exception of an early truncating variant, the variants showed adequate nuclear translocation but overall disturbed DNA-binding ability and promoter activation.

Variants absent from population and clinical databases. Almost all constituted putatively non-inherited de novo variants (8/10).

Functional studies provide evidence for loss of function in eight and gain of function in one obesity-associated POU3F2 variant. One variant did not impact POU3F2-promoter activation, leaving the possibility for further path-mechanisms.

Added comment: PMID: 37198333 reported 5 unrelated families with de novo variants in MCM6 gene. Two patients with the same missense variant p.(Cys158Tyr) in zinc finger domain presented with intra-uterine growth retardation, short stature, congenital microcephaly, endocrine features, developmental delay and urogenital anomalies.

In other three unrelated individuals different de novo missense variants were identified in the oligo nucleotide binding (OB)-fold domain. These patients had variable neurodevelopmental features including autism spectrum disorder, developmental delay, and epilepsy.

The clinical features and functional defects related to the zinc binding residue resembled those observed in syndromes related to other MCM components and DNA replication factors (Meier–Gorlin syndrome and Seckel syndrome), while de novo OB-fold domain missense variants were associated with more variable neurodevelopmental phenotypes (PMID: 37198333).

Added comment: Three different de novo missense variants identified in three unrelated individuals with developmental delay, hypotonia, autistic features, and variable dysmorphic features such as broad forehead and head circumference above average. Mutant mice displayed increased latency-to-peak response, suggesting the possibility of synaptic delay or myelination deficits. Functional studies confirmed the reduction of mutant HP1β binding to heterochromatin.

Added comment: 17 individuals from 16 families reported with mostly de novo variants. Variants were a mixture of missense, nonsense/frameshift (both NMD-predicted and not NMD-predicted) and microdeletions. In one family, only one parent was available for testing. In another family, 2 affected siblings had the variant but the variant was not identified in either parent suggesting germline mosaicism.

Functional testing of a subset of variants in Drosophila supported pathogenicity in most, but 2 missense variants showed no functional effect and were classified VUS. Episignature analysis (EpiSign) on patient DNA from blood showed a specific DNA methylation signature in patients with the variants classified pathogenic but not those classified VUS.

Phenotypes included mainly neurological abnormalities (mild to moderate ID/dev delay, motor delay, speech delay, and behavioural disorders) and facial dysmorphisms.

Other features included hypotonia (11/16), variable brain abnormalities on MRI (6/12), variable cardiac malformations (6/14). urogenital malformations e.g. hypospadias, cryptorchidism (6/13), scoliosis (5/17) and/or variable other skeletal abnormalities (10/17).

Added comment: PMID:21937992 reported a family with recessive missense KDM5A variant presenting with an undefined developmental disorder characterised with intellectual disability and facial dysmorphisms.

PMID:33350388 reported nine patients from seven unrelated families identified with variants in KDM5A, of which three unrelated patients harboured heterozygous variants, while six patients from four unrelated families had homozygous variants. These patients presented with autism spectrum disorder (ASD) and a spectrum of neurodevelopmental phenotypes including intellectual disability, lack of speech, developmental delay and motor impairment.

In addition, loss of KDM5A has resulted in repetitive behaviors, sociability deficits, cognitive dysfunction, and abnormal dendritic morphogenesis in mice.

This gene has already been associated with phenotype in Gene2Phenotype (biallelic inheritance with 'limited' rating), but not in OMIM.

Review for gene: DPYSL2 was set to AMBER
Added comment: This gene should be rated AMBER, as it has been associated with intellectual disability (ID) from two unrelated cases displaying monoallelic variants in DPYSL2/ CRMP2, and supported by functional studies. However, the evidence is not sufficient for green rating as there are variants reported in other (but different) genes in the two patients.

PMID:35861646 reported two cases identified with heterozygous variants (patient1: c.1693C>T (p.Arg565Cys); patient 2: c.42C>A (p.Ser14Arg). These patients had overlapping phenotypes including dysmorphic features, severe global developmental delay and hypoplasia of the corpus callosum. In addition, patient 2 was bed-ridden and could not roll out and had a history of myoclonic seizures and status epilepticus.

It should be noted that patient 1 is compound heterozygous for 2 missense variants in the EFCAB5 gene and was hemizygous for a maternally inherited missense variant in the GPKOW gene and patient 2 had 1 de novo missense variant in the COBLL1 gene and was compound heterozygous for 2 missense variants in the POTEF gene. The severity of the phenotypes between the two cases differs significantly and the additional variants may have possibly contributed to this phenotype.

Brain-specific Crmp2 knockout mice display neuronal development deficits and behavioural impairments associated with hypoplasia of the corpus callosum. In addition, functional studies performed in zebrafish and cell lines that the CRMP2 variants lead to the loss-of-function of CRMP2 protein and can cause intellectual disability.

This gene has not yet been associated with relevant phenotypes either in OMIM or in Gene2Phenotype.

Added comment: Comment on gene classification: This gene should be rated green as this gene has been associated with intellectual disability from six unrelated cases. However, the MOI should be set as "BIALLELIC, autosomal or pseudoautosomal" as five of these cases were reported with biallelic variants and only one case was reported with monoallelic variant.

PMID:28286008 reported a boy with compound heterozygous variants that was presented with developmental delay in 13 months and had severe intellectual disability and hyperactivity at nine years of age. He was nonverbal and wheelchair dependent because of spastic diplegia and ataxia.

PMID:30692597 reported a five year old boy identified with a homozygous ROBO1 variant who had combined pituitary hormone deficiency, psychomotor developmental delay, severe intellectual disability, sensorineural hearing loss, strabismus and characteristic facial features.

PMID:35227688 reported eight patients including the boy reported in PMID:30692597. Of the other seven patients, three were presented with intellectual disability. Of these three patients, two harboured compound heterozygous and one harboured homozygous variants.

PMID:35348658 reported a patient identified with monoallelic de novo variant (p.D422G) who presented with early-onset epileptic encephalopathy and had severe developmental delay.

This gene has not yet been associated with any phenotypes in OMIM or Gene2Phenotype.

Added comment: PMID: 36765070 reported three individuals from two unrelated families with a neurodevelopmental disorder characterized by speech and motor impairment with a similar facial gestalt comprising almond-shaped eyes, depressed nasal bridge, and a prominent Cupid’s bow with variable disease severity and progression. NGS analysis revealed bi-allelic loss-of-function variants in ATG4D gene. Based on the clinical, bioinformatic, and functional data, the author concluded that bi-allelic loss-of-function variants in ATG4D contribute to the pathogenesis of syndromic neurodevelopmental disorder.

Added comment: PMID: 34009673- patients with constitutional mosaic aneuploidy were found to have biallelic mutations in CENATAC(CCDC84). 2 adult siblings with mosaic aneuploidies, microcephaly, dev delay, and maculopathy. Both chet for a missense and a splice site deletion- but the paper days these both result in the creation of a novel splice site that leads to frameshifts and loss of the c-terminal 64 amino acids.

Gene is shown to be part of a spliceosome. CENATAC depletion or expression of disease mutants resulted in retention of introns in ~100 genes enriched for nucleocytoplasmic transport and cell cycle regulation, and caused chromosome segregation errors.

Functional analysis in CENATAC-depleted HeLa cells demonstrated chromosome congression defects and subsequent mitotic arrest, which could be fully rescued by wildtype but not mutant CENATAC. Expression of the MVA-associated mutants exacerbated the phenotype, suggesting that the mutant proteins dominantly repress the function of any residual wildtype protein.

Added comment: PMID: 36323681; Leitão E. et al. (2022) Nat Commun.13(1):6570:
Missense variant NM_012471.2:c.523C>T, p.(Arg175Cys in three brothers with intellectual disability (ID) and autistic spectrum disorder (ASD), inherited from an asymptomatic mother and absent in the maternal grandparents.
Whole cell patch clamp studies of HEK293 created by site-directed mutagenesis showed increased current of this calcium channel (constitutively opened).
(This variant is absent in gnomAD v2.1.1).

Also, the nonsense variant, c.965G> A, p.(Trp322*) was found in a high functioning ASD male (maternally inherited), NMD-predicted.

Other papers and TRPC5 variants that were cited to associate this gene with X-linked ID and/or ASD include:
PMID: 24817631; Mignon-Ravix, C. et al. (2014) Am. J.Med. Genet. A 164A: 1991–1997: A hemizygous 47-kb deletion in Xq23 including exon 1 of the TRPC5 gene. He had macrocephaly, delayed psychomotor development, speech delay, behavioural problems, and autistic features. Maternally inherited, and a family history compatible with X-linked inheritance (i.e., maternal great uncle was also affected, although not tested).

In addition, PMID: 36323681; Leitão E. et al. (2022) cites papers with the variants p.(Pro667Thr), p.(Arg71Gln) and p.(Trp225*).
NB. p.(Pro667Thr) is absent in gnomAD (v2.1.1), p.(Arg71Gln) is also absent (the alternative variant p.(Arg71Trp) is present once as heterozygous only). p.(Trp225*) is absent, and it should be noted that PTCs / LoF variants are very rare (pLI = 1).

However, looking further into the three references, the evidence is not as clear or as accurate as was stated.

The missense variant c.1999C>A, p.(Pro667Thr), was stated as de novo, but was actually maternally inherited but was still considered a candidate for severe intellectual disability (shown in the Appendix, Patient 93, with severe speech delay, autism spectrum disorder and Gilles de la Tourette). This patient also has a de novo MTF1 variant. Reference: PMID: 23033978; de Ligt, J. et al. (2012) N. Engl. J. Med. 367: 1921–1929).

Missense variant (de novo): c.212G>A, p.(Arg71Gln), was found as part of the Deciphering Developmental Disorders (DDD) study and is shown in individual 164 in Supplementary Table 2 of PMID: 33504798; Martin, HC. et al. (2021) Nat. Commun.12: 627. Also displayed in DECIPHER (DDD research variant) with several phenotype traits, but ID and ASD are not specifically mentioned.

Nonsense variant: c.674G>A. p.(Trp225*) was stated as de novo but was inherited (reference PMID: 28191890; Kosmicki, JA. et al. (2017) Nat. Genet. 49: 504–510. Supplement Table 7). This was a study of severe intellectual delay, developmental delay / autism. (NB. The de novo p.(Arg71Gln) variant from the DDD study is also listed (subject DDD 342 in Supplement 4 / Table 2).

Key clinical features: severely impaired global development apparent from infancy, feeding difficulties with failure to thrive, small head circumference, and dysmorphic facial features. Affected individuals have impaired intellectual development and hypotonia; they do not achieve walking or meaningful speech. Other neurologic findings may include seizures, hearing loss, ophthalmologic defects, and brain imaging abnormalities. There is variable involvement of other organ systems, including skeletal, genitourinary, cardiac, and possibly endocrine.

Further 3 unrelated patients identified with mild to moderately impaired intellectual development associated with a specific de novo heterozygous mutation in the SETD2 gene (R1740Q).

These are distinct clinically from Luscan-Lumish syndrome, which is characterised by overgrowth.; Changed publications: 29681085, 32710489; Changed phenotypes: Luscan-Lumish syndrome, MIM#616831, Rabin-Pappas syndrome,MIM# 620155, Intellectual developmental disorder, autosomal dominant 70, MIM# 620157

Multiple LOF variants classified as pathogenic or likely pathogenic in ClinVar and reported in the literature in multiple homozygote and compound heterozygote individuals affected with homocystinuria, e.g. c.19dup p.(Gln7fs) (PMID: 25218699; 12124992) and c.919G>A p.(Gly307Ser) (PMID: 7506602, 7581402, 8744616, 9889017, 23733603).

Multiple CBS variants reported in CBS deficiency (PMID: 12124992).

ClinGen classify as definitive for Homocysteinuria. Clingen states- Twenty-one unique variants were curated (missense, nonsense, frameshift, and splice site) in 15 probands from 8 publications, and three of these probands each had two affected siblings in whom CBS variants were identified (PMID 1301198, 10408774, 7762555, 12815602, 16307898, 25455305, 26667307, 29508359). Gene-disease relationship is supported by the biochemical function of CBS, which is consistent with the biochemical features in patients with homocystinuria (including elevated plasma total homocysteine and methionine) (PMID 13654400, 15890029), functional studies in yeast, bacteria, and cultured cells, including chaperone studies in fibroblasts from patients with homocystinuria (PMID 9590298, 25331909), as well as the biochemical and clinical features of mouse models (PMID 18987302) and enzyme replacement studies in mice (PMID 29398487).

Added comment: Six variants in GABRA3 encoding the alpha3-subunit of the GABA(A) receptor.
Five missense variants and one micro duplication were detected in four families and two sporadic cases presenting with a range of epileptic seizure types, a varying degree of intellectual disability and developmental delay, sometimes with dysmorphic features or nystagmus.
The variants co-segregated mostly but not completely with the phenotype in the families, indicating in some cases incomplete penetrance, involvement of other genes, or presence of phenocopies.
Overall, males were more severely affected and there were three asymptomatic female mutation carriers compared to only one male without a clinical phenotype.
Mechanism suggested - three detected missense variants are localised in the extracellular GABA-binding NH2-terminus, one in the M2-M3 linker and one in the M4 transmembrane segment of the alpha3-subunit. Functional studies in Xenopus leaves oocytes revealed a variable but significant reduction of GABA-evoked anion currents for all mutants compared to wild-type receptors. The degree of current reduction correlated partially with the phenotype.
Results reveal that rare loss-of-function variants in GABRA3 increase the risk for a varying combination of epilepsy, intellectual disability/developmental delay and dysmorphic features, presenting in some pedigrees with an X-linked inheritance pattern.

Added comment: PMID:36336956 describes a 9-year-old boy with severe DD, lack of speech, pyramidal signs, and limb ataxia who had a de novo missense variant Asp126His in FEM1C ascertained by WES. The equivalent variant introduced into the nematode C.elegans resulted in disabled locomotion caused by synaptic abnormalities and not muscle dysfunction.

An alternate change Asp126Val was reported in the DDD study de novo in a patient with uncharacterised developmental delay (PMID:28135719).

The Asp126 residue (but not either of the variants above specifically) was shown to be functionally important by in vitro studies (PMID:33398170;33398168). The residue is highly conserved and located in a region of missense constraint.

Borderline green, 2 patients and an animal model. Note all evidence points to the Asp126 residue being of specific importance.

Added comment: Six different missense variants were identified (de novo) in 11 affected individuals with neurodevelopmental disorders, with a broad spectrum of additional features, including epilepsy, aberrant growth parameters, skeletal and cardiac abnormalities. 9/11 probands have ID. In vivo and in vitro functional suggest that loss-of-function is not the mechanism of disease. The mechanism of disease is yet to be established.

Added comment: Two reportedly unrelated, consanguine families with the same hom stop mutation in PI4K2A, p.(Arg309Ter). Probands with seizures, developmental delay, hypotonia/dystonia, myoclonus and developmental delay. MRI showed extensive brain abnormalities including dysgenesis of the corpus callosum, ventriculomegaly, and white matter volume loss.

Functional studies showed cellular mislocalisation of the Arg309Ter truncated protein construct compared to WT and an missense control.

An earlier paper from 2018 described two additional probands with a different stop mutation, p.(Ser22Ter), and overlapping phenotypic presentation.

in 2011, a Pi4k2a knock-out mouse model was described. "Knock-out animals initially appeared normal but later develop a progressive neurological dis-ease characterized by tremor, limb weakness, urinary incontinence and premature mortality. Histological analysis revealed massive axonal degeneration in the spinal cord in the descending corticospinal tracts."

Added comment: -18 affected individuals from 11 unrelated families harbouring ultra-rare bi-allelic missense and loss-of-function LETM1 variants
-Most of the affected individuals (14/18, 78%) had an infantile-onset disease manifestation,
and 4/18 (22%) presented first symptoms between the ages of 1.5 and 2 years
-Variant types included missense, frameshift, stop loss, in-frame deletion and splice defect
-From biochemical and morphological studies, bi-allelic LETM1 variants are associated with defective mitochondrial K efflux, swollen mitochondrial matrix structures, and loss of important mitochondrial oxidative phosphorylation protein components

Added comment: PMID 36197437 Cospain et al 2022 report 11 individuals from 10 families with heterozygous PTC variants in exon 4/4 of the FOSL2 gene. All variants were predicted to escape NMD resulting in a truncated protein, with the truncation occurring proximal to the C-terminal domain (supportive functional studies).

In 10/11 families the variant occurred de novo in a single affected proband. In one family with 2 affected siblings, the variant was present in the siblings but absent in the unaffected parent likely due to gonadal mosaicism.

Clinical features included:
- Cutis aplasia congenital of the scalp (10/11)
- Tooth enamel hypoplasia and discolouration (8/9)
- Multiple other ectodermal features also noted e.g. small brittle nails, hypotrichosis/hypertrichosis, lichen sclerosis
- 5 individuals had cataracts (mostly bilateral, congenital/early childhood onset)
- 6/9 IUGR
- 5/9 postnatal growth restriction
- 7/9 developmental delay/ID (mild to severe)

Fevga, Tesson et al (2022 - PMID: 36073231) describe the features of 4 individuals, from 2 unrelated families, with biallelic pathogenic PTPA variants.

These presented with normal or delayed early milestones, learning disability and ID (mild to moderate) followed by progressive signs of parkinsonism (at the age of 11 yrs in 2 sibs, 15 yrs in another individual). Motor symptoms were responsive to levodopa and later to deep brain stimulation.

Linkage analysis in one consanguineous family followed by exome revealed homozygosity for a missense PTPA variant (NM_178001:c.893T>G/p.Met298Arg). Exome sequencing in affected subjects from the 2nd family revealed homozygosity for a further missense variant (c.512C>A/p.Ala171Asp). There were no other candidate variants for the phenotype following parental / segregation studies.

Role of the gene:
As the authors discuss, PTPA (or PPP2R4) is ubiquitously expressed in all tissues incl. brain and encodes a phosphotyrosyl phosphatase activator of the dimeric form of protein phosphatase-2A (PP2A). PP2A in turn, is the major Ser/Thr phosphatase in brain targeting a large number of proteins involved in diverse functions. Activation of PP2A is dependent on its methylation, which is negatively regulated by the PP2A-specific methylesterase (PME-1). By binding to PME-1, PTPA counteracts the negative influence of the former on PP2A. Pathogenic variants in genes encoding subunits/regulators of the PP2A complex (e.g. PPP2R1A or PPP2CA) are associated with neurodevelopmental disorders.

Variant studies:
Upon overexpression of wt and both variants in a HEK-293 cell line the authors demonstrated that both variants resulted in significantly reduced mRNA and protein levels (which for Ala171Asp were attributed to increased proteasomal degradation). Both variants were shown to result in impaired PP2A complex activation compared to wt.

Drosophila / animal models:
Pan-neuronal RNAi-mediated knockdown of ptpa in Drosophila resulted in an age-dependent locomotor dysfunction, reversible with L-DOPA treatment.
Previous studies in mice suggest cognitive/electrophysiological impairments upon downregulation of PP2A activity in transgenic mice.

Added comment: Based on Jia et al (2022 - PMID: 35977029) speech, motor delay as well as ID are observed in individuals harboring de novo pLoF variants in UBAP2L. The gene encodes a regulator of the stress granule (SG) assembly. Extensive evidence is provided on the effect of variants as well as the role of UBAP2L and other genes for components and/or regulation of SG in pathogenesis of NDDs. Among others a Ubap2l htz deletion mouse model (behavioral and cognitive impairment, abnormal cortical development due to impaired SG assembly, etc). Data from 26 previous studies, aggregating 40,853 probands with NDDs (mostly DD/ID, also ASD) suggest enrichment for DNMs in UBAP2L or other genes previously known and further shown to be important for SG formation (incl. G3BP1/G3BP2, CAPRIN1).

Details provided below.

Not associated with any phenotype in OMIM, G2P or SysNDD.

--------

Jia et al (2022 - PMID: 35977029) describe 12 affected individuals with heterozygous de novo pLoF variants in UBAP2L.

Phenotype: Features included hypotonia, speech (11/11) and motor delay (8/12), ID (8/10 with formal evaluation), variable behavioral concerns (ADHD 5/11, ASD in 4/10, etc). Seizures were reported in 7/12 with 3/10 having a formal diagnosis of epilepsy. Few had microcephaly (3/10). Facial dysmorphisms were common (9/9) and included abnormal palpebral fissures, deep prominent concha, high broad forehead, hypertelorism, thin upper lip and mild synophrys (each in 4 or less individuals). Short stature or skeletal alterations were described in some (4/10 each).

Role of the gene: UBAP2L encodes an essential regulator of stress granule assembly. Stress granules are membraneless cytoplasmic compartments in eukaryotic cells, induced upon a variety of stressors and playing a role in regulation of gene expression.

Variants identified : 9 nonsense/frameshift UBAP2L variants and 3 splicing ones were reported, in all cases as de novo events, upon trio/quad exome sequencing. All were absent from gnomAD. There were no other causative variants.

Variant effect/studies (NM_014847.4 / NP_055662.3) :
- Minigene assays revealed that the 3 splice variants all resulted in out-of-frame exon skipping.
- In patient fibroblasts one of these splice variants was demonstrated to result to reduced protein levels.
- 8 of the 9 nonsense/frameshift variants were predicted to result to NMD.
- 1 nonsense variant (c.88C>T/p.Q30*) was shown to result to decreased protein expression in patient fibroblasts, with detection of the protein using an antibody for the C terminus but not the N terminus. Protein N-terminal sequencing confirmed that the protein lacked the N terminus, with utilization of an alternative start site (11 codons downstream).
- Generation of HeLa UBAP2L KO cell lines resulted in significant reduction of SG numbers which was also the case for 4 variants studied, under stress conditions.
- The protein has a DUF domain (aa 495-526) known to mediate interaction of UBAP2L with G3BP1 (a stress granule marker) with deletions of this domain leading to shuttling of UBAP2L from the cytoplasm to the nucleus. Truncating variants upstream of the DUF domain were shown to result in nuclear localization.

Mouse model :
- The authors generated Ubap2l KO model with hmz deletion of Ubap2l resulting in a lethal phenotype (2.6% survived) and htz deletion leading to behavioral issues (low preference for social novelty, anxious-like behaviors) and cognitive impairment.
- Ubap2l haploinsufficiency resulted in abnormal cortical development and lamination with reduction of neural progenitor proliferation.
- Ubap2l deficiency was shown to impair SG assembly during cortical development both under physiological stress conditions or upon utilization of an oxidative stress inducer.

Additional evidence of UBAP2L and SG overall in pathogenesis of NDDs:
- Based on DNMs from 40,853 individuals with NDDs from 26 studies (9,228 with ASD, 31,625 with DD/ID) the authors demonstrate significant excess of DNM in 31 genes encoding SG components, regulators or both, the latter being the case for UBAP2L and 2 further genes (G3BP1 and G3BP2 - both with crucial roles in SG assembly).
- Excess dn splice-site (N=3) and missense (N=5) variants in G3BP1 were observed in the above cohort [c.95+1G>A, c.353+1G>T, c.539+1G>A / p.S208C, R320C, V366M].
- Excess dn missense (N=7) variants in G3BP2 were observed in the above cohort [p.R13W, D151N, E158K, L209P, E399D, K408E, R438C].
- Generation of G3BP1 or G3BP2 KO HeLa cell lines and immunofluorescence upon use of oxidative stress inducer revealed significant reduction of stress granules.
- Generation of HeLa cell lines for 5 G3BP1 mutants (R78C*, R132I*, S208C*, R320C*, V366M) and 7 G3BP2 mutants (p.R13W*, D151N*, E158K, L209P*, E399D, K408E, R438C) revealed that several (those in asterisk) resulted in significantly fewer SG formation under oxidative stress compared to WT while the subcellular distribution of the proteins under stress was identical to WT.
- Among the identified genes for SG enriched for DNMs, CAPRIN1 was implicated in previous publications as a NDD risk gene with 3 dn missense SNVs reported (p.I373K, p.Q446H, p.L484P). CAPRIN1 binding to G3BP1/2 has been shown to promote SG formation. Significant reduction of SG was observed in CAPRIN1 KO HeLa lines. p.I373K abolished interaction with G3BP1/2 and disrupted SG formation.

Added comment: PMID: 36044892; Twelve different variants reported in 23 affected individuals from 15 unrelated families with biallelic variants. All individuals had global developmental delay and intellectual disability. Consistent facial dysmorphisms included coarse facies, prominent forehead, board depressed nasal root, tented mouth, long smooth philtrum, and low-set ears. In vitro studies of missense variants demonstrated accelerated protein degradation via the autophagy-lysosomal pathway, while analysis of primary fibroblasts and granulocytes provided functional evidence of ER and nuclear envelope dysfunction.

- Biallelic variants in COX11 associated with infantile-onset mitochondrial encephalopathies in two unrelated consanguineous families, one with homozygous missense variant, another with homozygous frameshift variant.
- Functional studies supported pathogenicity of the missense variant, and showed that mutant COX11 fibroblasts had decreased ATP levels which could be rescued by CoQ10.
- RNA studies suggested the mutant transcript with p.(Val12Glyfs*21) is not degraded by nonsense mediated decay.

Added comment: Dias et al (2022 - PMID: 35916866) describe the phenotype of 11 unrelated individuals with monoallelic de novo (or suspected de novo) missense (N=9) or truncating (N=2) ZMYND8 variants. One of these subjects was previously reported by Suzuki et al (2020 - PMID: 32530565).

Features included speech delay/language difficulties (9/11), motor delay (9/11), ID (in 10/11 - profound in 1, moderate in 2), CHD (7/11 - PDA, VSD, ASD, pulmonary stenosis, etc), hearing or vision impairment (7/11). Seizures were reported in few (in text 5/11, table 2/11). Variable non-familial facial features were present in (9/11).

As the authors discuss, ZMYND8 encodes a multidomain protein playing a role in transcription regulation, chromatin remodeling, regulation of super enhancers, DNA damage response/tumor suppression.

The protein is broadly expressed in brain and shows highest expression in early development.

Molecular modeling and/or a yeast two-hybrid system were suggestive of disrupted interaction of ZMYND8 with Drebrin (missense variants in PWWP domain) or GATAD2A (variants in MYND domain).

Neuronal Zmynd8 knockdown in Drosophila resulted in deficits in habituation learning.

Added comment: Homozygosity mapping on one large consanguineous Bedouin kindred showed three affected children (out of the ten) to be homozygous for NM_002802.3:c.983T>C; p.(Ile328Thr).

Drosophila rescue experiments were carried out. Transgenic studies using drosophila with the silenced ortholog Rpt2 gene were rescued by the human wild-type PSMC1.

Three of the ten offspring of healthy consanguineous parents of Bedouin Israeli ancestry were affected with a similar phenotype of failure to thrive, developmental delay and severe intellectual disability, spastic tetraplegia with central hypotonia, chorea, as well as hearing loss. None of the three achieved verbal communication or ambulation (sitting / standing) at any age. They had mild dysmorphism of borderline dolichocephaly and microcephaly, prominent bushy eyebrows, flat midface, long nasal bridge and micrognathia. All three had micropenis with undescended testes. One of the affected (as a toddler) underwent thorough endocrinological analysis: testosterone and gonadotropin levels were low.

Added comment: 6 missense variants and 1 nonsense variant (NOT NMD-predicted, single-exon gene) reported in 7 males and 1 female with neurodevelopmental disorders. Phenotypes included dev delay, mild to severe ID, delayed or absent speech, seizures and brain MRI anomalies (in some patients).

The nonsense variant was identified in two affected brothers but not in the mother, suggesting it was de novo in the maternal germline. The variant in the one affected female was de novo. All other variants in hemizygous males were inherited from an unaffected mother. In one case, the variant was also identified in the unaffected grandmother.

Functional studies showed some but not all variants displayed impaired membrane transport and impaired excitatory synapse-promoting effects. Conditional knockout mice exhibited impaired long-term memory and abnormal gait.

Added comment: PMID 35543142 O'Grady et al 2022 report 14 unrelated individuals with heterozygous PRPF8 variants and ID, dymorphic features and epilepsy (7/14). Short stature, abnormal gait and cardiac anomalies also reported. 11 variants identified were de novo, 1 variant - maternal mosaicism, 1 variant - duo sequencing (not identified in mother, father could not be sequenced). 1 individual did not have parental testing. Cardiac anomalies varied and included benign cardiac tumour, dilated cardiomyopathy, dilated aortic root (COL5A2 VUS also identified), bicuspid aortic valve, cardiac arrest, self-resolving ASD/VSD.

Heterozygous PRPF8 variants previously associated with retinitis pigmentosa. 1 out of the 14 individuals in this cohort had a diagnosis of RP. RP variants noted to cluster in the C'terminal MPN domain. The individual with RP in this paper had a variant in the preceding RNAase H homology domain near the C-terminus. Not all of the individuals in this paper had formal ophthalmological examination

Added comment: 2 unrelated patients with ID, microcephaly, short stature, dysmorphic features reported with biallelic variants:

P1 (3yo male): homozygous start-loss variant (2 hets and 0 hom in gnomAD). Functional testing showed a small amount of full-length protein was translated, and BUB1 recruitment to kinetochores was nearly undetectable.
P2 (16yo female): compound heterozygous for a canonical splice variant (1 het and no hom in gnomAD) and an NMD-predicted frameshift variant (absent from gnomAD). The splice variant was shown to result in an in-frame deletion of 54 amino acids in the kinase domain. P2 cells have reduced protein levels but essentially no kinase activity.

BUB1 patient cells have impaired mitotic fidelity.

Homozygous Bub1 disruption in mice is embryonic lethal (PMID:19772675). A hypomorphic mouse is viable with increased tumourigenesis with ageing and aneuploidy (PMID:19117986). A kinase-dead mouse does not show increased tumourigenesis but does have a high frequency of aneuploid cells (PMID:23209306)

Added comment: Combined oxidative phosphorylation deficiency-39 (COXPD39) is an autosomal recessive multisystem disorder resulting from a defect in mitochondrial energy metabolism. Affected individuals show global developmental delay, sometimes with regression after normal early development, axial hypotonia with limb spasticity or abnormal involuntary movements, and impaired intellectual development with poor speech. More variable features may include hypotonia, seizures, and features of Leigh syndrome on brain imaging. There are variable deficiencies of the mitochondrial respiratory chain enzyme complexes in patient tissues.

Phenotypes for gene: ADD1 were set to Intellectual disability, corpus callosum dysgenesis, and ventriculomegaly; no OMIM #
Review for gene: ADD1 was set to GREEN
Added comment: 4 unrelated individuals affected by ID and/or complete or partial agenesis of corpus callosum, and enlarged lateral ventricles. WES found loss-of-function variants - 1 recessive missense variant and 3 de novo variants. The recessive variant is associated with ACC and enlarged lateral ventricles, and the de novo variants were associated with complete or partial agenesis of corpus callosum, mild ID and attention deficit. Human variants impair ADD1 protein expression and/or dimerization with ADD2. Add1 knockout mice recapitulate corpus callosum dysgenesis and ventriculomegaly phenotypes. Three adducin genes (ADD1, ADD2, and ADD3) encode cytoskeleton proteins that are critical for osmotic rigidity and cell shape. ADD1, ADD2, and ADD3 form heterodimers (ADD1/ADD2, ADD1/ADD3), which further form heterotetramers. Adducins interconnect spectrin and actin filaments to form polygonal scaffolds beneath the cell membranes and form ring-like structures in neuronal axons. Adducins regulate mouse neural development, but their function in the human brain is unknown.

Added comment: 4 children from 3 related families with developmental delay, hypotonia, seizures, failure-to-thrive, strabismus, drooling, recurrent otitis media, hearing impairment, genitourinary malformations, and common facial features (arched eyebrows, prominent eyes, broad nasal bridge, low-hanging columella, open mouth, thick lower lip, protruding tongue, large low-set ears, and parietal bossing). WES revealed a homozygous frame-shift variant (p.Thr612Glnfs*22) in PROSER1. This encodes the proline and serine rich protein 1, part of the histone methyltransferases KMT2C/KMT2D complexes. PROSER1 stabilizes TET2, a member of the TET family of DNA demethylases which is involved in recruiting the enhancer-associated KMT2C/KMT2D complexes and mediating DNA demethylation, activating gene expression. Therefore, PROSER1 may play vital and potentially general roles in gene regulation. No functional assays and 3 related families.

Added comment: 2 individuals with profound intellectual disability, epilepsy, white matter atrophy, microcephaly, and dysmorphic features, who carry damaging de novo heterozygous variants in DROSHA. Both variants are missense, absent from gnomad. Both individuals noted to have Rett-like features.

Functional studies in patient fibroblasts showed one of the missense altered the expression of mature miRNA. Fruit fly models with homozygous LOF variants die during larval stages. introduction of the missense seen in the patients was able to partially rescue this phenotype suggesting LOF is not the mechanism.
