Review for gene: ATXN7L3 was set to GREEN
gene: ATXN7L3 was marked as current diagnostic
Added comment: This study reports 9 unrelated individuals with de novo heterozygous variants in ATXN7L3 identified through WES testing and GeneMatcher. Core clinical features included: global motor and language developmental delay, hypotonia, and dysmorphic features (hypertelorism, epicanthal folds, blepharoptosis, small nose, small mouth, and low-set posteriorly rotated ears). Variable features included: feeding difficulties, seizures, mild periventricular leukomalacia, and structural cardiac abnormalities.

A recurrent nonsense variant [p.(Arg114Ter)] was found in 5/9 individuals. The other variants were 1 frameshift [p.(Ser112LysfsTer12)] and 3 missense variants [p.(Ile71Thr), p.(Ser92Arg), and p.(Leu106Pro)]. They investigated the effects of the recurrent nonsense variant [p.(Arg114Ter)] in fibroblasts of an affected individual. ATXN7L3 protein levels were reduced, and deubiquitylation was impaired (as indicated by an increase in histone H2Bub1 levels). This is consistent with the previous observation of increased H2Bub1 levels in Atxn7l3-null mouse embryos, which have developmental delay and embryonic lethality.

Pathogenic variants in deubiquitinating enzymes (DUBs) have been implicated in neurodevelopmental disorders (ND) and congenital abnormalities. ATXN7L3 is a component of the DUB module of the SAGA complex, and two other related DUB modules, and serves as an obligate adaptor protein of 3 ubiquitin-specific proteases (USP22, USP27X or USP51).

Added comment: 1 case with generalised lipodystrophy, growth retardation, congenital cataracts, severe developmental delay and progeriod features. Trio WGS identified compound heterozygous variants in SUPT7L (missense causing abnormal splicing + frameshift). Variants validated with Sanger. SUPT7L encodes a component of the core structural module of the STAGA complex - a nuclear multifunctional protein complex that plays a role in various cellular processes (e.g. transcription factor binding, protein acetylation, splicing, and DNA damage control). Immunolabelling in fibroblasts from patient showed complete absence of SUPT7L protein. Transcriptome data from individual revealed downregulation of several gene sets associated with DNA replication, DNA repair, cell cycle, and transcription.

Added comment: PMID:38422122 reported the identification of 10 individuals from seven kindreds from four different ethnicities with biallelic PTCRA variants (homozygous in five kindreds and compound heterozygous in two kindreds).

Six of these 10 patients were clinically asymptomatic at their most recent evaluation, while other four patients displayed infection, lymphoproliferation, and/or autoimmunity with an onset during their teens or in adulthood. One of these patients died from SARS-CoV-2 pneumonia at the age of 24 years. Patient 9 had a small thymus on MRI at the age of 2 years, whereas P5 and P6 had no visible thymus at the ages of 13 and 8 years, respectively. Three of the nine patients with pLOF PTCRA variants tested were found to produce autoantibodies, several of which were associated with clinical manifestations. Anti-thyroid autoantibodies and/or clinically overt thyroiditis were found in three of the nine patients. P7, who suffered from recurrent herpes infections, had autoantibodies against type I interferons.

Two of those identified variants are hypomorphic and are associated with autoimmunity. In addition, there is extensive functional and epidemiological data available.

Added comment: Wang paper PMID: 37943610

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”.

Added comment: PMID: 36649075- a patient whose fetal ultrasound revealed polyhydramnios, enlarged abdomenand bladder, and prune belly syndrome. During infancy/childhood profound gastrointestinal dysmotility, cerebrovascular disease, and multiple strokes. Described as a multisystemic smooth muscle dysfunction syndrome. Patient was found to have a de novo SNP in MIR145 NR_029686.1:n.18C>A. The MIR145transcript is processed into two microRNAs, with the variant position at nucleotide 3 of miR-145-5p.

Transfection of an siRNA against mutant miR145-5p induced a notable decrease in the expression of several cytoskeletal proteins including transgelin, calponin, and importantly, smooth muscle actin. Hybridization analysis and miR RNA-seq demonstrated a decrease in expression of miR145-5p in the presence of mutant miR145-5p. RNA-seq showed that the differentially expressed genes were substantially different between patient and control fibroblasts.

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.

Mendeliome v0.7004 PRIM1 Zornitza Stark changed review comment from: - 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/agammaglobulinaemia, and lymphopaenia accompanied by intermittent anaemia/thrombocytopaenia. 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 v0.4520 SLC12A2 Zornitza Stark edited their review of gene: SLC12A2: Added comment: Monoallelic :
DD/ID was a feature in >= 6 individuals with monoallelic de novo SLC12A2. An individual with an exon 22 truncating variant was reported to have normal milestones and cognitive function. Exon 21 variants have been described in individuals with rather isolated hearing impairment (possibly some associated motor delay, but normal cognition). Hearing impairment was also reported in 2/6 patients with variants in other exons (1 missense / 1 frameshift).

Biallelic :
DD/ID was reported in at least 3 individuals in literature. Hearing impairment has been reported on 2 occasions (although this was not probably evaluated in all subjects).

---

Monoallelic SLC12A2 mutations :

► Individuals with de novo mutations and developmental disorder were first identified by the DDD study (2017 - PMID: 28135719). 5 of them have been reported in detail by McNeill et al (below).

► McNeill et al (2020 - PMID: 32658972) report on 6 individuals with neurodevelopmental disorder due to de novo SLC12A2 mutation. All presented DD or ID ranging from mild to severe. ASD was reported in 3/6. Sensorineural hearing loss was a feature in 2/6 with the remaining having normal formal evaluations. Brain, cardiac and/or additional malformations were reported in a single individual. Following non-diagnostic prior work-up (CMA, FMR1 or other investigations) trio exome sequencing revealed missense (4/6) or truncating variants (2/6).

Three additional individuals (incl. a father and his son) with missense variants in exon 21 (NM_001046.3 / p.Glu979Lys and p.Glu980Lys) presented with bilateral sensorineural hearing loss. Speech and/or motor delay reported in these cases were attributed to the hearing impairment/vestibular arreflexia (cognitive abilities not tested).

SLC12A2 encodes sodium-potassium-chloride transporter 1 (also NKCC1).

The GTEx project has identified 8 isoforms. In brain both exon 21-containing/deleted isoforms are expressed (cited Morita et al 2014 - PMID: 24695712). As the authors discuss, RNA-seq of the developing mouse cochlea suggests that the exon 21 containing isoform is the single transcript expressed. Evidence from RNA-seq data (BrainSpan project) and literature suggests that the significant amounts of exon 21 lacking isoforms in fetal brain compensate for the deleterious effects of exon 21 variants and explain the lack of NDD in relevant patients.

Slc12a2 (NKCC1) null mouse model has demonstrated that the transporter plays a role in accumulation of the potassium rich endolymph in the inner ear, with NKCC1 absence causing sensorineural deafness and imbalance. Slc12a2 display cochlear malformations, loss of hair cells and hearing impairment (cited Delpire et al 1999 - PMID: 10369265). The brain phenotype has not been studied extensively, although loss of Slc12a2 has been shown to inhibit neurogenesis (cited: Magalhães and Rivera et al. - PMID: 27582690).

Slc12a2 null zebrafish display a collapse of the otic vesicle and reduced endolymph (Abbas and Whitfield, 2009 - PMID: 19633174) relevant to the human hearing disorder.

In vitro assessment of NKCC1 ion transporter function in Xenopus laevis, supported the deleterious effect of the identified variants (significant reduction in K+ influx). Using available single cell RNA-seq data the authors further demonstrated that SLC12A2 expressing cells display transcriptomic profiles reflective of active neurogenesis.

► Delpire et al (2016 - PMID: 27900370 - not reviewed in detail) described a 13 y.o. girl harboring a de novo 11-bp deletion in SLC12A2 exon 22. This individual reached developmental milestones on time and had a NORMAL cognitive function. Hearing was seemingly normal. Features included orthostatic intolerance, respiratory weakness, multiple endocrine abnormalities, pancreatic insufficiency and multiorgan failure incl. gut and bladder. Exome in the proband, parents and 3 unaffected sibs suggested SLC12A2 as the only candidate for her phenotype. Functional analyses in Xenopus laevis oocytes suggested that a non functional transporter was expressed and trafficked to the membrane as the wt. Detection of the truncated protein at higher molecular sizes suggested either enhanced dimerization or misfolded aggregate. There was no dominant-negative effect of mutant NKCC1. In patient fibroblasts a reduced total and NKCC1-mediated K+ influx.

► Mutai et al (2020 - PMID: 32294086) report on several individuals from 4 families, harboring variants within exon 21 or - in one case - at it's 3' splice-site (leading to skipping oe this exon at the mRNA level). All subjects were investigated for severe/profound hearing loss (in line with the role of exon 21-included isoforms in cochlea. The variant segregated with hearing impairment in 3 generations of a family while in all other subjects the variant had occured as de novo event. Despite motor delays (e.g. the subject from fam2 could not hold head or sit at the age of 10m / the proband in Fam3 was able to hold his head and walk at 6 and 20 m respectively) behavior and cognition were commented to be within normal range.

Biallelic SLC12A2 mutations:

► Anazi et al (2017 - PMID: 29288388) briefly reported on a 3 y.o. boy (17DG0776) with central hypotonia, neonatal respiratory distress, failure to thrive, global DD and microcephaly and a skeletal survey suggestive of osteopenia. After non-diagnostic prior investigations (CMA revealing a 1p duplication classified as VUS, extensive metabolic workup), WES revealed a homozygous SLC12A2 splicing variant [NM_001046.2:c.2617-2A>G].

► Macnamara et al (2019 - PMID: 30740830) described a 5.5 y.o. male with sensorineural hearing loss, profound delays in all developmental areas among several other features (choanal atresia, failure to thrive, respiratory problems, absent sweat and tear production or salivation, GI abnormalities). Genetic testing for several disorders considered (cystic fibrosis, spinal muscular atrophy, sequencing and del/dup analysis of mtDNA) was normal. CMA revealed paternal uniparental isodisomy for chr. 5 and WGS a homozygous 22kb deletion in SLC12A2. This was followed by confirmation of homozygosity in the proband, heterozygosity of the unaffected father, delineation of breakpoints (chr5:127441491-127471419). mRNA studies in patient fibroblasts confirmed deletion of ex2-7, splicing of ex1 directly to ex8 and introduction of a premature stop codon in ex9. qRT-PCR confirmed that mRNA is likely subjected to NMD (expression ~80% of control). Western blot confirmed absence of the protein in the patient's fibroblasts. Again mouse models are thought to recapitulate the hearing defect but also the deficient saliva production (cited Evans et al 2000 - PMID: 10831596). Again the authors speculate a role of SLC12A2 in brain development based on evidence from murine models (migration, dendritic growth, increse in neuron density through regulation of GABAergic signalling (Young et al 2012 - PMID: 23015452). Hypotheses are also made on a regulatory relationship between NKCC1 and CFTR based on mRNA data from the ko mouse model.

► Stödberg et al (2020 - PMID: 32754646) reported 2 sibs with a complex neurodevelopmental disorder due to compound heterozygosity for a frameshift SLC12A2 variant and a splicing one (NM_001046:c.1431delT and c.2006-1G>A). Both presented hypotonia, neonatal S. aureus parotitis and respiratory problems (incl. apneas). While the older sib died at the age of 22 days, the younger one had persistent respiratory issues incl. a dry respiratory mucosa motivating metabolic, immunology investigations and testing for CF. She displayed microcephaly (OFC -2.5 SD, H was also -3.5SD), severe intellectual disability. MRI was suggestive of white matter and basal ganglia abnormalities. Other features incl. hearing impairment, and lack of tears,saliva and sweat, constipation and intestinal malrotation. There was facial dysmorphism. The variants were the only retained following WGS of the 2 affected sisters, parents and an unaffected brother. The splicing variant was shown to result in skipping of exon 13, while the indel in NMD. Again the authors discuss that the deficient saliva production, impaired hearing and GI problems are recapitulated in the mouse model (several refs provided).; Changed rating: GREEN; Changed publications: 28135719, 32658972, 27900370, 32294086, 29288388, 30740830, 32754646; Changed phenotypes: Kilquist syndrome, deafness, intellectual disability, dysmorphic features, absent salivation, ectodermal dysplasia, constipation, intestinal malrotation, multiple congenital anomalies; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal

Added comment: - PMID: 32181500 (2020) - Three patients from two independent consanguineous families with homozygous variants (c.3353G>A, p.Ser1118Asn and c.1289delA, p.His430Profs7*) in the FNIP1 gene. Both variants segregated with the disease phenotype in each family. Clinically, patients presented with combined immunodeficiency, cardiac findings (hypertrophic cardiomyopathy, Wolff‐Parkinson‐White syndrome), and myopathy of skeletal muscles with motor DD. Authors note phenotypic overlap with the murine model of FNIP1 deficiency, but no functional analyses of the variants or patient cells were performed.

- PMID: 32905580 (2020) - Three cases from unrelated families, all harbouring novel biallelic variants in FNIP1. Clinical manifestations in all patients include hypertrophic cardiomyopathy, severe and/or recurrent infections, absent circulating B-cells, and agammaglobulinemia; as well as either severe or intermittent neutropenia in two cases. Functional studies showed impairment of B-cell metabolism, including disruptions to mitochondrial numbers/activity and the PI3K/AKT pathway.

Analysis of patient cells indicated that the mutant transcript escaped nonsense-mediated mRNA decay, and most likely produced a truncated protein, although antibody studies were unable to detect a truncated protein. Possible dominant-negative effect. NB a more proximal nonsense variant was also reported inherited in a family with an unaffected mother: loss of function variants may not cause a phenotype.

PMID: 31036916 - a single de novo patient reported in a neurodevelopmental disorder cohort. Authors note another de novo case with the exact same variant (p.Arg126Gln) from the DDD study, and a 3rd patient from GeneMatcher with the same de novo missense again. Decipher shows this variant to be in a highly constrained region of the protein.

Have selected AMBER for now - not sure if GeneMatcher findings can be used as a 3rd case
