Mendeliome v1.3486 PPFIA2 May Tun Hla Maw changed review comment from: Encodes Liprin-alpha2.
Predominantly expressed in brain in the pre- and post-synaptic compartments.
Liprin has three domains with N-terminal coiled coil domain (CCD), central (IDRs) and three tandem C-terminal sterile alpha motif (SAM) domains.

Gene-disease association: neurodevelopmental disorder.
Mode of pathogenicity is unclear; haploinsufficiency has not been proven as disease-causing mechanism.

Evidence summary:
Previously reported heterozygous de novo variants in two unrelated individuals with a neurodevelopmental disorder. Large cohort studies identified seven additional individuals with rare de novo variants with intellectual disability or developmental delay. Reported variants are mostly missense, and the rest includes non-sense, in-frame deletion, splice site variants. Eight out of these variants are located in the known functional domains (CCD, IDR, SAM). All of these variants were absent in gnomAD.

Other phenotypes in these individuals include IUGR, macrocephaly, dystonia, choreatic movement, nystagmus, ataxia, hyperactivity, coarsened gyration, immature opercularization and a coarse corpus callosum, and hypotonia.

Functional studies:
Homozygous mice with PPFIA2-knockout developed a neurologic phenotype as well as ophthalmologic features. Heterozygous mice did not have apparent phenotype.

Mendeliome v1.3486 SSPO Sarah Milton changed review comment from: The HGNC approved symbol for this gene is SSPOP which refers to SCO-spondin pseudogene. Recently, it has been demonstrated this gene produces a functional protein; subcommissural organ-spondin, which plays a role in neural development and function. Given the previous pseudogene status most annotation will include n. as opposed to c. numbers (including in gnomAD v4).

PMID: 41077560 describes 4 individuals from 3 families with biallelic variants in SSPOP with a neurodevelopmental disorder. Phenotype is encompassed by epilepsy (onset <2 years old), developmental delay, autism and behavioural issues.
Variant types include missense, frameshift and splice site.

No homozygous nonsense/frameshift variants in gnomad v4. (some hom splice site).

Supportive functional studies including zebrafish knockout with epileptiform activity. Mouse knockout demonstrated reduced reissner’s fibre formation/smaller brain ventricles/spinal curvature anomalies.

It was noted by authors another publication PMID: 32028786 discussed 2 related individuals - a grandmother and grandchild with homozygous frameshift variants in SSPOP (exact variant not provided) who both were just documented to have cervical cleft, no mention of ID/epilepsy.

Added comment: Encodes Liprin-alpha2.
Predominantly expressed in brain in the pre- and post-synaptic compartments.
Liprin has three domains with N-terminal coiled coil domain (CCD), central (IDRs) and three tandem C-terminal sterile alpha motif (SAM) domains.

Gene-disease association: neurodevelopmental disorder.
Mode of pathogenicity is unclear; haploinsufficiency has not been proven as disease-causing mechanism.

Evidence summary:
Previously reported heterozygous de novo variants in two unrelated individuals with a neurodevelopmental disorder. Large cohort studies identified seven additional individuals with rare de novo variants with intellectual disability or developmental delay. Reported variants are mostly missense, and the rest includes non-sense, in-frame deletion, splice site variants. Eight out of these variants are located in the known functional domains (CCD, IDR, SAM). All of these variants were absent in gnomAD.

Other phenotypes in these individuals include IUGR, macrocephaly, dystonia, choreatic movement, nystagmus, ataxia, hyperactivity, coarsened gyration, immature opercularization and a coarse corpus callosum, and hypotonia.

Functional studies:
Homozygous mice with PPFIA2-knockout developed a neurologic phenotype as well as ophthalmologic features. Heterozygous mice did not have apparent phenotype.

PMID:39729134 (2024) reported an 11-year-old male of Indian descent with childhood-onset ataxia and severe sensorineural hearing loss. Genetic analysis identified heterozygous 3' splice site variant in the PNPT1 gene (c.2014-3 C > G).

PMID:39899068 (2025) reported a 1-year-8-month-old female proband of Brazilian descent with Spinocerebellar Ataxia 25 that presented with progressive ataxia, cerebellar atrophy, and sensory neuropathy. She was identified with a novel heterozygous truncating variant in PNPT1 (c.2068del), which she inherited from her father. Although the father was previously reported as asymptomatic, he was affected with axonal and demyelinating polyneuropathy but not ataxia upon detailed examination.

PMID:39924761 (2025) reported two unrelated families, where all individuals presented with sensory ataxic neuropathy (SAN), while some individuals developed cerebellar signs. Analysis of WGS variant data through the 100,000 Genomes Project identified two different heterozygous variants in these families. Family 1 underwent a 'quad' study and the previously reported c.2014‐3C>G variant segregated in all affected family members and was absent in all unaffected family members. Sanger sequencing confirmed segregation in two other individuals. c.2014‐3C>G is the same variant that was found in the 3-generation Australian family reported by PMID:35411967, where unaffected family members harboured the variant. A novel nonsense variant (c.2143C>T/ p.Arg715Ter) was found in both affected members of Family 2.

PMID:40757543 (2024) reported an 18-year-old male presented with slowly progressive infancy-onset spasticity of the lower limbs and cerebellar ataxia, associated with painless strabismus, intellectual disability, urinary incontinence, bilateral progressive visual loss, and cognitive decline since early adolescence. The patient was identified with a heterozygous pathogenic variant c.162-1G>A in PNPT1 gene.; Changed rating: GREEN; Changed publications: 35411967, 39729134, 39899068, 39924761, 40757543

Added comment: PMID:38296633 (2024) reported a two-generation family affected by a distinctive phenotype comprising a lipomatous frontonasal malformation, anosmia, cutis aplasia of the scalp and/or sparse hair, and congenital heart disease. A heterozygous c.310G>C variant encoding p.(Asp104His) within the BTB domain of KCTD15 was identified in the affected father and daughter via exome sequencing and the variant segregated with the phenotype. A de novo heterozygous c.263G>A variant encoding p.(Gly88Asp) was identified via targeted DNA sequencing in a similarly affected sporadic patient.

There is some functional evidence available from structural analyses, which demonstrated that missense substitutions act through a dominant negative mechanism by disrupting the higher order structure of the KCTD15 protein complex.

Added comment: RAVINE leukoencephalopathy (RLE) is a hereditary autosomal recessive disease characterized by typical clinical and radiological signs that has so far been observed only in patients of Reunionese origin. The term RAVINE is a French acronym for the main clinical features of the disease: Réunion, Anorexie, Vomissements Incoercibles, signes NEurologiques (Reunion, Anorexia, Intractable Vomiting, NEurological signs). Patients with RLE carry the IVS1-1778A>G mutation of the SLC7A2 gene in the homozygous state.

Onset is in infancy. Death typically occurs before the age of 28months in a very narrow time window (23.0±2.2months).

PMID 41015522 summarises data from 40 affected individuals.

Added comment: Addition of this review to Mendeliome, was only on the hyperinsulinism panel

2 families with 36 individuals with AD inheritance of diabetes mellitus or insulinomatosis (adult-onset recurrent hyperinsulinemic hypoglycemia caused by multiple insulin-secreting neuroendocrine tumours of pancreas). WES identified the same missense MAFA mutation (p.Ser64Phe, c.191C>T) segregating with both phenotypes of insulinomatosis and diabetes in both families. The p.Ser64Phe mutation was found to impair phosphorylation within the transactivation domain of MAFA and profoundly increased MAFA protein stability under both high and low glucose concentrations in β-cell lines. In addition, the transactivation potential of p.Ser64Phe MAFA in β-cell lines was enhanced compared with wild-type MAFA. The human phenotypes associated with the p.Ser64Phe MAFA missense mutation reflect both the oncogenic capacity of MAFA and its key role in islet β-cell activity.

Variant segregated with disease in 6x affected hemizygous males (4x live-born and 2x terminated male fetuses). Carrier females are apparently normal (no brain MRI was performed).

Exome sequencing identified start loss variant, c.2T>C p.(Met1Thr). Functional analyses identify that the variant results in a protein lacking 91 amino acids from the N-terminus and leads to abnormally increased AMOT protein levels (increased stability due to loss of degradation signals), which disrupts epithelial and endothelial barrier integrity.

Mendeliome v1.3368 TRIM49 Bryony Thompson changed review comment from: Two unrelated families (consanguineous marriage in Family 2; possible maternal uniparental disomy in Family 1) carry rare biallelic TRIM49 variants (c.1184C>A and c.1134_1137delTCTT) that are absent from 7 283 in‑house controls and have extremely low gnomAD frequencies. Functional experiments in human RPE cell lines demonstrate that loss of TRIM49 impairs autophagic flux, ULK1 expression and POS phagocytosis, and that overexpression of wild‑type TRIM49 rescues these defects whereas mutant TRIM49 (M1/M2) does not (Box 438, Box 440, Box 439). This constitutes convincing functional evidence for pathogenicity in two families.

Added comment: PMID: 41029903 One patient with a suspected neurometabolic disorder; congenital blindness and suspected Leber Congenital Amaurosis, microcephaly, failure to thrive, profound global developmental delay and extensive delayed myelination on MRI. AT 10 he was non-verbal and non-ambulatory with regression of motor skills and -3SD for height and weight. Compound heterozygous for Phe264Leu (539 hets but no homs in gnomad v4) and Glu348Lys (over 8000 hets and 24 homs in gnomad v4).

in compound heterozygous iPSCs a severe 75% reduction in BCAT1 protein levels was seen, but mRNA levels were normal suggesting the variants affect protein stability or increased degradation.

PMID: 41024252 8 patients from 7 families with joint hyperlaxity, with or without short stature and renal disease. 6 families were homozygous for p.(Cys539Trpfs*64) while the other two were homozygous for p.(Lys681*). Paper described both as founder variants but they are rare/absent in gnomad.

Joint hyperlaxity (7), chronic kidney disease/FSGS (2) small echogenic kidneys (3), acute kidney injury (1), dysmorphic features (6), short stature (6), speech delay (3).

One patient also had epilepsy, developmental delay and spasticity however c.728+1G>A in WDR45 explained this part of her phenotype. Other patients also had more severe outlying symptoms with no other explanation mentioned: 1 with developmental delay, hearing loss, brain malformations, skeletal abnormalities, and another a 3 year old who passed away following a complex medical course including blue sclera, proximal tibial fracture, severe respiratory distress due to a chest infection, and acute kidney injury.

2) A boy with a phenotype resembling CHARGE syndrome (multiple anomalies involving the eyes, ears, cleft lip, and palate, and intellectual disability) with retinal dystrophy (p.A288T/p.R303C),
3-7) 4 consanguineous families homozygous for p.R225C, including a set of cousins.
CDK9 variants demonstrated decreased kinase activity. One of the studies suggested the extent the kinase activity is reduced may account for the absence/presence of the CHARGE-like phenotype with retinal dystrophy

Mendeliome v1.3353 SF1 Sarah Milton changed review comment from: SF1 is involved in the first step of spliceosome complex assembly by recognizing the intron branchpoint consensus sequence at the 3′ splice site of the pre-mRNA. It is also involved in regulating alternative splicing

PMID: 40987292 describes 15 affected individuals with a neurodevelopmental disorder with monoallelic variants in SF1. Affected individuals had developmental delay, mild to moderate ID, behavioural disorders, seizures (3/15), brachydactyly (5/15), nail hypoplasia (5/15).
Variant types included missense and high impact LOF (nonsense and frameshift).

Most variants were appropriately rare in gnomAD v4 however one reported variant had 9 hets.
pLI for SF1 is 1 with overall few LOF variants in gene.

Supportive functional studies reported in publication. SF1 deficient neural progenitor cells showed altered gene expression in genes involved in neuronal differentiation/synaptic transmission and axonal guidance.

Added comment: WES in 68 subjects with HLHS identified 1 individual with co-occurrence (i.e. digenic) of a SAP130 gene variant (p. S639G) and PCDHA13 gene variant (p. A22V). GnomAD frequencies for variants are: 0.00003% (PCDHA13 variant) and 0.01% with numerous homozygotes (SAP130 variant). The PCDHA13 variant is situated in a region highly conserved across the PCDHA gene family (which is highly homologous), especially PCDHA10 which is the ortholog of mouse Pcdha9.

Mouse and zebrafish modeling showed that Sap130 mediates left ventricular hypoplasia, and Pcdha9 increases penetrance of aortic valve abnormalities. Mutations in Sap130 and Pcdha9 were validated by CRISPR–Cas9 genome editing in mice as being digenic causes of HLHS.

Added comment: 4 unrelated female patients with primary infertility caused by oocyte/embryo defects, from a large cohort of 3,627 patients. WES identified rare biallelic variants in SPDYC gene (p.R52Vfs∗50, p.R188C, p.P287H). Overexpression of mutant SPDYC mRNA in mouse oocytes caused disruption of the ability of the protein to overcome milrinone-mediated inhibition of meiotic resumption with two of the variants (p.R52Vfs∗50 and p.R188C). SPDYC is involved in crucial processes involving cyclin-dependent kinases during the phase transition of the mitotic cell cycle.

Added comment: 2 patients from 2 unrelated families with acephalic spermatozoa syndrome. WES identified biallelic variants in CCDC188 gene (1 x homozygous, 1 x compound heterozygous). The variants (c.481C > T [p.Gln161*] and c.1022 + 1G > A [p. K325Afs*110]) were rare in gnomAD and segregated in the family with heterozygous carrier parents. Western blotting, RT-PCR, qPCR, and immunofluorescence showed depletion of CCDC188 protein (and SUN5 and PMFBP1 protein) in patient sperm. Mutations in SUN5 and PMFBP1 genes account for 75% patients with acephalic spermatozoa syndrome.

Mendeliome v1.3301 CPD Sarah Milton changed review comment from: CPD encodes carboxypeptidase D which is part of the metallocarboxylpeptidases family. These enzymes are zinc dependent and cleave c terminal arginine and lysine. Which in turn has a role in production of nitric oxide which is known to play role in the cochlea.

PMID: 41026541 describes 5 individuals from 3 families with biallelic missense variants in CPD who have prelingual onset bilateral profound SNHL. No syndromic features were noted in affected probands.
All variants appropriately rare in gnomad v4 for a rare recessive disorder.
No homozygous loss of function variants in gene in gnomad v4.
All families consanguineous.

Functional studies demonstrated reduction in nitric oxide levels in patient cells as well as increased apoptosis with rescue upon introduction on L arginine. Proposed mechanism of disease is loss of function.
Drosophila studies demonstrated disrupted Johnston’s organ morphology and impaired auditory transduction with partial rescue by arginine. Other supportive functional models discussed in paper.

Authors suggest potential treatment of affected individuals with arginine supplementation.

The patient also had congenital heart disease, bilateral duplicated kidneys, cleft palate, inguinal hernias.This patient also had immunodeficiency with thymic aplasia, absence of TRECs on NBS, profound lymphopenia with death at 3 months of age from CMV pneumonitis. Prenatal features include severe polyhydramnios.

PMID: 29681102 Bouman et al 2018 report a male neonate of consanguineous North African descent with thoracic vertebral anomalies, rib anomalies, dysmorphism and severe respiratory deficiency resulting in neonatal death at 9 days of age. Extra-skeletal anomalies included aberrate right subclavian artery, non-functional left kidney and tetehterd cord.Prenatal features included increased NT (8.0mm), scoliosis (15+4 weeks), IUGR/kyphoscoliosis/small thoracic cage (28+2 weeks). Trio WES identified a homozygous start-loss DMRT2 variant (c.1A>T p.Met1?) classified as a VUS. In addition, a homozygous canonical acceptor site variant in the non-canonical transcript was detected in SH3PXD2B associated with Frank-Ter Haar syndrome which is also known to have skeletal features including rarely respiratory failure leading to neonatal death (PMID: 31978614). The parents were heterozygous for both sets of variants and the unaffected sibling was homozygous wild-type.

PMID: 16387892 Seo et al 2006 report a knockout mouse model with abnormal rib and sternal development, respiratory insufficiency.

Overlapping features between the 2 unrelated patients and the mouse model include severe skeletal manifestations. However, one of the reported cases also had an alternative genomic finding relevant to skeletal issues. Other overlapping features observed in the 2 patients and not in the mouse include congenital heart defects and CAKUT.

Mendeliome v1.3288 CPD Sarah Milton changed review comment from: CPD encodes carboxypeptidase D which is part of the metallocarboxylpeptidases family. These enzymes are zinc dependent and cleave c terminal arginine and lysine. Which in turn has a role in production of nitric oxide which is known to play role in the cochlea.

PMID: 41026541 describes 5 individuals from 3 families with biallelic missense variants in CPD who have prelingual onset bilateral profound SNHL. No syndromic features were noted in affected probands.
All variants appropriately rare in gnomad v4 for a rare recessive disorder.
No homozygous loss of function variants in gene in gnomad v4.

Functional studies demonstrated reduction in nitric oxide levels in patient cells as well as increased apoptosis with rescue upon introduction on L arginine. Proposed mechanism of disease is loss of function.
Drosophila studies demonstrated disrupted Johnston’s organ morphology and impaired auditory transduction with partial rescue by arginine. Other supportive functional models discussed in paper.

Authors suggest potential treatment of affected individuals with arginine supplementation.

At least 7 individuals reported. Affected individuals had varying clinical features including cataracts, retinal dystrophy, hearing loss, myopathy, ataxia, seizures, global developmental delay, diabetes, Wolff-Parkinson-White arrhythmia, hypertrophic cardiomyopathy, and hypogonadotropic hypogonadism. Lab investigations revealed elevated blood lactate and elevated creatine kinase. Muscle biopsy, when performed, generally showed reduced activities of complexes I, I+III, III, and/or IV. Brain imaging was normal in some cases. In one individual brain imaging revealed changes in the basal ganglia and diffuse atrophy with an enlarged cisterna magna and in another showed changes in the cerebral white matter.

Heteroplasmy levels were variable – some individuals had the highest levels in muscle with the variant being undetectable in other tissues while others had the variant present at homoplasmy in multiple tissues. Northern blotting and single fiber testing further supported variant pathogenicity.

At least 8 individuals reported. Clinical features seen in affected individuals range from isolated hearing loss to mitochondrial myopathy to mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) and myoclonus epilepsy, ragged red fibers (MERRF). One case of fatal neonatal lactic acidosis has been reported. Intrafamilial variability has been observed.

Muscle biopsy often shows COX-negative fibers and/or ragged red fibers. A combined mitochondrial chain respiratory deficiency (commonly involving complexes I and IV) may also be observed in muscle biopsies. Heteroplasmy levels in affected individuals are often near homoplasmy in muscle and lower in tissues such as blood and urine, although homoplasmy across multiple tissues has also been seen. One individual had mitochondrial myopathy with heteroplasmy levels as low as 37% heteroplasmy in muscle.

Multiple single fiber studies and cybrid analyses were performed in these patients and are supportive of variant pathogenicity.

Three unique variants (m.4332G>A, m.4369_4370insA, m.4381A>G) reported in three probands across 3 publications. Single fiber testing further supported the pathogenicity of several of these variants. Age of onset in affected individuals was five years old, teens, and 20 years old. Clinical features in affected individuals included stroke-like episodes, hearing loss, myopathy, and Leber Hereditary Optic Neuropathy (LHON). Brain imaging was variable. Muscle biopsies showed ragged red fibers and COX-negative fibers. Metabolic screening investigations were only reported in one individual and showed high cerebrospinal fluid (CSF) lactate with normal blood lactate. Heteroplasmy levels in affected individuals were highest in muscle when multiple tissues were assessed (61-87% in muscle).

Multiple individuals reported. The condition was first described in a 10-year-old girl with exercise intolerance, myopathy, and short stature with mildly elevated serum lactate. Subsequent publications have shown a consistent phenotype involving a mitochondrial myopathy (typically childhood onset) with elevated lactate. Chronic external progressive ophthalmoplegia (CPEO) is not common but has been reported. Basal ganglia lesions and Leigh syndrome spectrum/mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) overlap have also been reported in one patient. Retinitis pigmentosa has also been reported. Muscle biopsy often shows classic findings of mitochondrial myopathy with COX-negative and ragged red (or blue) fibers. Combined OXPHOS deficiencies in muscle are also observed.

More than 5 individuals reported. Age of onset in affected individuals varied from adolescence to the 40s. Clinical features included stroke-like episodes, seizures, myoclonus, ataxia, optic atrophy, retinal dystrophy, cataracts, hearing loss, hypogonadism, and mood disorder. Cerebellar vermis hypoplasia and signal changes in the basal ganglia, dentate nuclei, temporal lobes, and occipital lobes were seen on brain imaging.

Tissue biopsies identified ragged red fibers and COX-negative fibers. Laboratory investigations showed increased blood and cerebrospinal fluid lactate. Decreased activities of complexes I and IV were variably seen in muscle. Heteroplasmy levels of the variants in affected individuals ranged from 81% to homoplasmic in muscle, 33-87% in urine, 1-60% in blood, and undetectable to homoplasmic in fibroblasts. Single fiber testing, cybrid analysis, and Northern blot analysis further supported variant pathogenicity.

This gene-disease relationship is also supported by known biochemical function and functional alteration in patient and non-patient cells (in vitro functional assays demonstrated reduced rates of mitochondrial translation as a result of variants in MT-TH; PMID: 24920829, 21704194).

Four variants reported in at least 6 individuals. Age of onset in affected individuals varied from early in life to the 20s. Clinical features included hypertrophic cardiomyopathy, myopathy, peripheral neuropathy, exercise intolerance, headache, seizures, ataxia, dystonic posturing, optic atrophy, retinal dystrophy, cataracts, and hearing loss. Progressive atrophy and bilateral basal ganglia calcifications were seen on brain imaging.

Tissue biopsies identified ragged red fibers and decreased COX histochemical activity in muscle. Lab values showed increased blood lactate and increased creatine kinase. Decreased activities of complexes I, III, and IV were observed in biopsied muscle.

Heteroplasmy levels of the variants in affected individuals ranged from 88-92% in muscle, 40-56% in urine, undetectable to 32% in blood, 27% in buccal samples, and was undetectable when assessed in fibroblasts. Single fiber testing and cybrid analysis further supported variant pathogenicity. This gene-disease relationship is also supported by known biochemical function and functional alterations in patient cells (in vitro functional assays demonstrated reduced rates of mitochondrial translation as a result of variants in MT-TG; PMID: 10090480).

Over 30 individuals reported. Age of onset in affected individuals varied from childhood to >60 years. Clinical features in affected individuals included mitochondrial myopathy, MELAS, myoclonic epilepsy and ragged red fibers (MERRF), chronic external progressive ophthalmoplegia (CPEO), Gitelman syndrome, epilepsy, epilepsia partialis continua (EPC), chronic kidney disease, retinal dystrophy, sensorineural hearing loss, neuropathy, and neurologic/cognitive/psychiatric decline. Some affected individuals had normal brain imaging while others had cerebral, cerebellar, and/or brainstem atrophy.

Muscle biopsies showed ragged red fibers, COX-negative fibers, and decreased respiratory chain enzyme activities in some cases, although activities were normal in other individuals. Laboratory investigations showed variable lactate levels (normal to elevated in blood, cerebrospinal fluid, and/or urine) and elevated creatine kinase (CK).

Heteroplasmy levels in affected individuals were highest in muscle when multiple tissues were assessed, and ranged from 58%-homoplasmic in muscle; 0-70% in hair, 0-homoplasmic in blood, fibroblast, and urine; and in one individual was 63% in a buccal sample.

At least 3 variants reported in unrelated individuals. These variants were generally present at high levels of heteroplasmy in muscle tissue and at lower to undetectable levels in other tissues such as blood, saliva, buccal tissue, urine, and fibroblasts, highlighting the diagnostic importance of muscle biopsy in MT-TD-related primary mitochondrial disease. Single fiber studies were performed in several individuals with results supporting variant pathogenicity.

This gene-disease association is also supported by functional implication given protein interaction with the multitude of other mitochondrial translation proteins linked to primary mitochondrial disease (PMID: 30030363 ). Respiratory deficient yeast strains due to a single variant in MT-TD have been created and compelling rescue studies have been performed (PMIDs: 7024270, 3054486). E. coli carrying the m.7526A>G variant were also shown to have significantly decreased aminoacylation rates (PMID: 19535463).

There were 3 scoreable probands across >10 publications from 1996-2022. Notably, while cybrid analyses were performed (PMID:36039763), one of the variants, m.5783G>A, was excluded from scoring for three reasons: 1.) the reported phenotype of isolated hearing loss was non-specific and incompletely penetrant, but also 2.) the biochemical impact in cybrids was mild - moderate, and 3.) there was reduction in expression of mitochondrial replication genes (TWNK ~30% of control in cybrids) suggesting an alternative aetiology might be responsible for the biochemical impact reported.

The gene-disease association for MT-TC is also supported by the known interaction with a multitude of other mitochondrial translation proteins (PMID:30030363) and respiratory chain studies and Northern blot analysis supporting MT-TC dysfunction leading to Complex I deficiency (PMID:35252560).

Over 70 affected individuals reported. Two variants, m.1555A>G and m.1494C>T, are recurrent.

These variants are predominantly associated with hearing loss. Some individuals with this variants have normal hearing, others have hearing loss following aminoglycoside exposure, and others have hearing loss and no known aminoglycoside exposure. Age of onset of hearing loss ranged from infancy (after aminoglycoside exposure) to adulthood. Hearing loss has been reported to be variable, stable in some individuals and progressive in others.

Additional variants in this gene have been reported to be associated with primary mitochondrial disease, however insufficient clinical detail was provided and/or there was a lack of comprehensive analyses excluding other causes, therefore these additional variants were not included in the ClinGen curation (m.827A>G – PMIDs: 16650816, 16782057, 18261986; m.961delTinsC - PMIDs: 7550368, 10326749; m.1027A>G – PMIDs: 23328039, 21205314, 20100600; m.1095T>C – PMIDs: 11313749, 11079536, 15637703).

Seven probands with m.10063T>C have been reported across five publications, all of whom had LHON. These cases were scored with reduced points by ClinGen given the mild impact this variant has been shown to have on complex I function. While three other missense variants (m.10543A>G, m.10591T>G, m.10680G>A) have been reported, the ClinGen Expert Panel agreed there was only sufficient evidence of pathogenicity for the m.10663T>C variant. Cases with m.10680G>A and m.10543A>G and m.10591T>G were reviewed but excluded from scoring due to a lack of compelling functional evidence to support pathogenicity. The m.10543A>G variant has been modeled in E. coli and showed a very mild reduction in NADH dehydrogenase activity (74% of control), which was not sufficient to be included in scoring.

Multiple individuals reported. Age of onset in affected individuals ranged from 9 months old to childhood. Clinical features in affected individuals included Leigh syndrome spectrum, myopathy, ophthalmoplegia, and ptosis. Muscle biopsies revealed ragged red fibers and complex I deficiency. Metabolic screening labs showed elevated lactate and creatine kinase (CK). Heteroplasmy levels were >95% in blood, fibroblasts, and muscle in the individual with Leigh syndrome spectrum. However in the other two individuals with predominantly myopathic features, the variant was present at >94% in muscle and undetectable in other tissues tested.

Mendeliome v1.3143 PRKCI Sangavi Sivagnanasundram changed review comment from: Multiple reported variants in affected individuals mainly presenting with lower lip pits and orofacial clefts (OFCs). Some individuals presented with a more severe phenotype inclusing seizures, ID/DD and urogenital anomalies. Supportive zebrafish model supporting a loss-of-function mechanism was performed on three recurrent variants [c.389G>A (p.Arg130His), c.1148A>G (p.Asn383Ser), and c.1155A>C (p.Leu385Phe)] however there is not enough evidence to show that LoF is the mechanism of disease.

The gene is not constrained for LoF in gnomAD and there are no pathogenic SNVs reported in ClinVar at this present time. Amber until further evidence is published in support of this gene-disease association.

Gbadegesin et al (2014); Hall et al (2018) 2 x families reported with FSGS (USA) and missense variants G618C (v4: absent) and R431C (v4: 63 hets, 0 hom). R431C was identified in 6 affected family members and absent in 6 unaffected family members. G618C was present in the proband and absent in 4 unaffected family members, the other 2 affected individuals from this family were not genotyped (deceased). Missense demostrated as LoF with both in vitro and in vivo (zebrafish). R431C was shown to disrupt interaction with CD2AP (primarily LoF effect), causing downstream hyperactivation of the PI3K/AKT/mTOR/Rac1 signaling pathway, which drives podocytes hypermotility.

Geminiganesan et al (2021) 1 x 2 year old child (India) with early-onset steroid resistant nephrotic syndrome, whole-exome sequencing and genome-wide linkage studies, a missense variant in ANLN was identified p.Thr821Met (v4: 508 hets, 0 hom).

Zhang et al (2023) 3 x children with steroid resistant nephrotic syndrome (China). 2 x missense (p.M1099I - LP (v4:1 het, 0 hom), p.S140T - VUS (v4: 6 hets, 0 hom) and 1 x stop gain reported p.R39X - LP ( v4: 1 het, 0 hom).

Lin et al (2023) 3 x unrelated individuals with missense E841K (China, v4: 618 hets, 2 hom). In famly A the variant was de novo, in family 2 only the proband as tested, in family 3 the variant was inherited from an affected father. 4 x unaffected individuals did not have the variant. Knockout mouse model inconclusive, did not show any effect until 36 weeks. Zebrafish model was also inconclusive.; Changed publications: 24676636, 30002222, 34819827, 38322629, 37957688

Added comment: 1 individual with retinitis pigmentosa with onset at 18yrs. Trio WGS identified biallelic missense variants in BAIAP3 gene (c.556C>G [p.Arg186Gly] and c.3099C>G [p.His1033Gln]). Both variants were very rare in gnomAD, and the healthy brother was heterozygous for one variant. BAIAP3 interacts with SNARE proteins, whose function is essential for endosome-mediated retrograde trafficking. Single-cell RNA sequencing profiling showed enhanced expression of the BAIAP3 gene in ciliated cells, astrocytes, excitatory and inhibitory neurons, and enteroendocrine cells. Confocal microscopy analysis showed elongated cilia in patient-derived and BAIAP3-depleted fibroblasts compared to control cells.

Added comment: 6 individuals from 6 unrelated families (4/6 consanguineous) presenting with neonatal diabetes onset <4mths (6/6), severe microcephaly (6/6), epilepsy (5/6), and developmental delay (4/6).

Whole genome sequencing identified biallelic variants in TMEM167A gene. Variants were homozygous in 5/6 families, and variant types were missense (4), frameshift (1), and splice (1), and all variants were rare/unreported in gnomAD. Segregation studies not reported in paper.

Microcephaly, epilepsy and diabetes syndrome has 2 known associated genes (IER3IP1 and YIPF5) which encode proteins involved in endoplasmic reticulum to Golgi trafficking. TMEM167A is highly expressed in developing and adult human pancreas and brain. Both TMEM167A depletion in EndoC-βH1 cells and knock‑in of p.Val59Glu variant in iPSC-derived β cells sensitized β cells to ER stress. The p.Val59Glu variant impaired proinsulin trafficking to the Golgi and induced iPSC-β cell dysfunction.

Added comment: PMID: 40926052: 1x cHet individual with primary microcephaly (-2 SD at birth and -3 SD at 5yo), motor delay, enlarged bilateral ventricles on MRI, horizontal nystagmus. Two frameshift variants identified, p.Lys15Glufs*9 (5’ NMD-escape; 432 hets, 2 homs in gnomAD v4) and p.Asp40Lysfs*5 (NMD-predicted; filtered out in v4).

CETN3-KO hCOs (human cerebral organoids) were significantly smaller than control hCOs.
The identified patient variants were introduced into WT iPSCs. Western blot analysis demonstrated a complete loss of CETN3 protein in both CETN3-KO cells and CETN3-mutant iPSCs. These were then used to generate hCOs, both of which exhibited reduced size compared to their respective controls.

Forebrain-specific Cetn3-ablated mice were also generated. At embryonic day 13.5 a significant but subtle reduction in forebrain size was detected in Cetn3-KO mice compared to control, while no difference was observed at P0.

Added comment: PMID: 40930097 6 patients from 5 families with neuroanatomical, craniofacial, and skeletal anomalies on prenatal ultrasound/MRI, all homozygous for variants in SNAPIN. 2 stopgain, 1 canonical splice, 5 missense. common phenotypes: ventriculomegaly 5/6, cerebellar hypoplasia/atrophy 5/6, clubfeet 4/6, corpus callosum agenesis 4/6, flexion contractures 4/6, microcephaly 3/6, micrognathia/retrognathia 4/6. The patients with the nonsense or splice variants did not survive the perinatal period, while those with missense survived into early childhood.

This paper also mentions a 7th patient reported in PMID: 26539891, who has ID, microcephaly, cortical atrophy, bulbar and cerebellar hypoplasia, sensorineural polyneuropathy, and hypotonia. They are homozygous for a missense variant Asn55Tyr. Of note, the other paper report this as Arg55Trp and one of their patients also has this variant, based off the transcript information provided in both papers Arg55Trp is correct.

PMID: 40930097 Knockout zebrafish models recapitulated the human phenotype. This phenotype was rescued by injecting WT human SNAPIN RNA. Injection with the 2 missense variants observed in patients in this study was able to partially rescue the phenotype but it was significantly worse than the rescue with WT injection. One of these missense variants is absent from gnomad (Arg55Trp) while the other (Glu49Asp) has 167 hets and 1 hom.

Review for gene: MCMDC2 was set to GREEN
Added comment: MCMDC2 encodes minichromosome maintenance domain-containing 2. It is involved in meiotic recombination and double stranded break repair for maintenance of fertility.

6 male individuals have been described thus far with homozygous missense/nonsense/fs variants with non obstructive azoospermia. Loss of function is the proposed mechanism of disease.

MCMDC2 knockout mice have issues with double stranded break repair in meiosis and subsequent aberrant gametogenesis.

1 female individual has been described with a homozygous nonsense variant with premature ovarian insufficiency, in the same publication a heterozygous female was also described to have the same phenotype. Functional studies on variants in these two individuals demonstrated homologous repair efficiency to be reduced compared to wild type.

Homozygous LOF variants are absent in gnomAD v4.

Review for gene: SLC38A6 was set to AMBER
Added comment: The study identified SLC38A6 variants in 71 unrelated Chinese ET families (≈9.2% of families) and 47 unrelated sporadic cases, with 15 distinct protein‑altering variants. However, many of the 15 variants are >2% in the East Asian population, which is inconsistent with the incidence of essential tremor in the population (~1%). The study does not contain any statistical enrichment analyses or case-control analyses. It also reports incomplete segregation and non-segregation of variants (called a phenocopy by the authors). A null mouse model (Slc38a6-/-) displays tremor and delineated cerebellar cellular abnormalities. In vitro assessment of 3 of the most common missense variants (p.Y108F [gnomAD total 0.0002; East Asian 0.006, p.M281T [gnomAD total 0.0015; East Asian 0.0227] and p.G318S [gnomAD total 0.0021; East Asian 0.0278]) significantly impaired L-arginine (L-Arg) uptake in HeLa cells. Given the prevalence of the reported variants in the East Asian population, the genetic evidence for this gene-disease association is limited.

Added comment: De novo LoF TRPC4AP variant identified on WES in a child with thyroid dyshormonogenesis.
179 patients with CHTD sequenced using a panel of target genes identifying four variants in TRPC4AP. During development, Choukair et al. showed that Trpc4ap is expressed in the brain, the thyroid bud, and the kidney of the African clawed frog (Xenopus laevis). This team showed that disabling Trpc4ap in the African clawed frog leads to thyroid hypoplasia during development. It was also shown that TRPC4AP interacted with IKBKG which activates the NF-κB signaling pathway and regulates the genes involved in the growth and survival of thyrocytes. Furthermore, the NF-kB would control the expression of NKX2-1, PAX8, TPO, NIS, and TG.18 The authors conclude that TRPC4AP would be a new candidate gene for TDs. Insufficient clinical cases for green. Candidate gene.

One individual exhibited epileptic encephalopathy and developmental delay, while the other showed common variable immune deficiency and glucose dysregulation. Actin polymerization was significantly decreased in individual 1, whereas it was increased in individual 2. Insulin-secreting cell lines expressing the LIMK1 variant of individual 1 exhibited significantly slower exocytosis, contrasting the rapid and uncontrolled exocytosis in individual 2. Intriguingly, both variants led to increased overall insulin secretion.

Added comment: Five homozygotes from 3 families (1 family segregating a deletion of the promoter and 5'-untranslated region of DHRS3, the other 2 a missense variant p.(Val171Met)), manifested a congruent phenotype, including coronal craniosynostosis, dysmorphic facial features, congenital heart disease (4/5 individuals), and scoliosis (5/5 individuals). Transcription of DHRS3 in whole blood cells from 2 homozygotes for the promoter/5'-untranslated region deletion was 90% to 98% reduced. Cells transfected with a DHRS3-Val171Met construct exhibited reduced retinaldehyde reduction capacity compared with wild-type, yielding reduced retinol and elevated RA; correspondingly, plasma from homozygous patients had significantly reduced retinol and elevated RA (exceeding the normal range), compared with controls and heterozygous relatives.

Three additional homozygous missense variants of DHRS3 (p.(Val110Ile), p.(Gly115Asp), and p.(Glu244Gln)) were shown to reduce catalytic activity in vitro and/or in vivo but were associated with normal or different phenotypes that did not meet the threshold to assign likely pathogenicity.

Added comment: Two individuals reported from unrelated families, presenting with DD/ID, intermittent hypoglycaemia and metabolic acidosis. Genetic testing identified compound heterozygous variants c.635dup p.(Asn212Lysfs*7) and c.1055C > T p.(Pro352Leu) in Patient 1, and a homozygous variant c.943A > Gp.(Met315Val) in Patient 2. Patient's fibroblasts and MTERF3 knockdown cells showed impaired mitochondrial respiration and reduced levels of OXPHOS complexes I, III, and IV. Transcription of MT-ND5, ND6, COII, and COIII was reduced, while other mitochondrial genes were upregulated. Wild-type MTERF3 expression restored these defects, but the variant Pro352Leu from patient failed to rescue mitochondrial dysfunction.

Added comment: PMID 40569305: consanguineous preterm male infant with a clinical picture of advanced kidney dysfunction and severe renal salt-wasting, highly suggestive of prenatal onset Bartter syndrome. Patient's follow-up was characterized by severe polyuria; episodes of hyponatremia, hypokalemia, and hypochloremia; and metabolic alkalosis and hyperuricemia. Homozygous variant in the TFCP2L1 gene identified. TFCP2L1 is a transcription factor required for normal kidney development, that regulates acid-base and salt-water homeostasis.

PMID 33097957: infant who developed CKD by the age of 2 months and had episodes of severe hypochloraemic, hyponatraemic and hypokalaemic alkalosis, seizures, developmental delay and hypotonia together with cataracts. Homozygous LoF variant.

TFCP2L1 is localized throughout kidney development particularly in the distal nephron. TFCP2L1 induced the growth and development of renal tubules from rat mesenchymal cells. Conversely, the deletion of TFCP2L1 in mice was previously shown to lead to reduced expression of renal cell markers including ion transporters and cell identity proteins expressed in different segments of the distal nephron. TFCP2L1 localized to the nucleus in HEK293T cells only upon coexpression with its paralog upstream-binding protein 1 (UBP1). A TFCP2L1 mutant complementary DNA (cDNA) clone that represented the patient's mutation failed to form homo- and heterodimers with UBP1, an essential step for its transcriptional activity.

Added comment: Single individual with homozygous missense variant reported, p.Phe267Ser.

18-year-old male presenting with spasticity, ataxia, cognitive decline, and white matter abnormalities on MRI. Molecular dynamics simulations revealed that F267 is a stabilizing residue within a β-strand of the zinc finger domain, forming π-stacking and hydrophobic interactions that are lost upon substitution with serine, leading to structural instability, increased flexibility, and protein unfolding. Despite normal transcript and protein expression, ZNF319-F267S mislocalized to the cytoplasm due to disruption of its bipartite nuclear localization signal (NLS), resulting in impaired interaction with importin α1 (KPNA1). Functional analysis confirmed that the variant disrupts nuclear transport and prevents transcriptional activation of genes involved in myelination. Protein interaction network and gene ontology analysis highlighted ZNF319's role in transcriptional regulation and its localization in the CHOP-C/EBP transcriptional complex. Expression profiling demonstrated ZNF319 enrichment in oligodendrocytes and white matter regions, correlating with the observed leukoencephalopathy.

PMID: 39048559 - Significant enrichment of KRT32 variants (p=3.06e-4) in 58 PRP cases vs 364 healthy controls (4 variants - individual 1: c.344G>A (p.Arg115Gln - 10 hets gnomAD v4.1), individual 2: c.477_478del (p.Thr160fs), individual 3: c.607C>T (p.Arg203Cys - 71 hets gnomAD v4.1), and individual 4: c.685T>C (p.Cys229Arg - 18 hets gnomAD v4.1). Validation cohort of 44 PRP cases vs 436 healthy controls identified an additional 2 variants (individual 5: c.907G>A (p.Glu303Lys - 3 hets gnomAD v4.1), individual 6: c.937A>G (p.Ile313Val - 30 hets gnomAD v4.1). A combined analysis of the KRT32 gene in both the discovery and validation cohorts revealed a significant p value of 1.73 e-6. The KRT32 expression patterns (location of protein expression) were altered in PRP cases with the KRT32 variants. In vitro analysis demonstrated that the 6 variants (all located in the IF rod domain) exhibited varying degrees of attenuation in inhibiting the NF-κB signaling pathway. A Krt32 knockout mouse model recapitulates the human PRP-like phenotype.
PMID: 40814173 - a single family with loose anagen hair syndrome co-segregating (c.296C>T; p.Thr99Ile) in a large family; however, the AF in the European population is 0.3% in gnomAD v4.1 (6 homozygotes), which is higher than expected for a dominant condition. In vitro functional assay showing the variant alters interaction with KRT82, however, only WT & the variant were assessed (no positive control).

Added comment: 4 unrelated individuals with thoracic aortic dilatation/aneurysm (3/4), congenital heart defect (3/4), high palate (3/4), hypertelorism (3/4), flat feet (3/4). learning issues/ID (2/4).

WES/WGS identified 4 rare predicted deleterious missense variants in ADAMTS6 gene [p.(Leu814Arg), p.(Asp319Asn), p.(Ala147Thr), p.(Ile810Leu)]. 2/4 variants were de novo, 1/4 was inherited (no parental phenotype info), 1/4 unknown status. Note: THSD4 gene, encoding ADAMTSL6, is associated with aortopathy disorder.

Functional studies (patient-derived fibroblasts) demonstrated that the variants impair ADAMTS6 secretion or function resulting in increased deposition of FBN1 and FBN2, and therefore extracellular matrix accumulation and microfibril disorganization. One variant, p.(Leu814Arg), further disrupted the Hippo and TGFβ signalling pathways and altered cell adhesion. Adamts6 (S149R/S149R) mice showed ventricular septal defects and accumulation of FBN1 and FBN2 in the outflow tracts.

Proposed name of condition: CHAN syndrome (Connective tissue, Heart defect, thoracic Aortic aneurysm, and Neurodevelopmental) syndrome.

Added comment: 2 brothers from non-consanguineous family with oligoasthenoteratozoospermia (OAT). WES identified missense variant in TCFL5 gene (c.1207G>A, p.E403K). Western blotting and immunofluorescence showed no significant effect on the expression of 'mutant' TCFL5. Dual-luciferase reporter assay revealed a serious impact on its transcriptional regulatory function.
The variant disrupted the normal transcription of crucial genes involved in spermatogenesis (DMRT1, DAZL, SYCE1, SPACA1, CNTROB, IFT88, HOOK1 and SPATA6). Tcfl5+/- male mice manifest infertile due to OAT, while Tcfl5-/- mice can not be generated.

Added comment: PMID: 40601774 3 siblings with Ritscher-Schinzel syndrome and a homozygous missense in COMMD4 NM_017828.5:c.122T>G; p.Leu41Arg. All three individuals died in infancy and the authors suggest there could be a dual diagnosis to explain the severity.

This variant was expressed in a H4 neuroglioma cell line with COMMD4 knocked out, and showed an enhanced degradative turnover compared to WT when treated with cyclohexamide. Western blot in HEK293T cells showed a decrease in the steady-state abundance of COMMD4.

Knock out of COMMD4 protein leads to destabilization of the Commander complex.

Added comment: A cohort of 6 patients with developmental delay (5/6), corpus callosum hypoplasia (4/6), microcephaly (1/6), seizures (3/6), and ID (2/6). 2 patients also had gastrointestinal motility disruption. All 6 have de novo variants in TMEM184B, 5 missense 1 canonical splice. 1 of the missense variants has 35 hets in gnomad but the rest are absent. The authors also say they are aware of a 7th patient with overlapping features by personal communication.

A knockout zebrafish model showed a dose dependent reduction in head size and body length in larvae. Knock-in of 2 of the missense variants also showed head size and body length reduction, but the other missense did not. However the other three missense failed to rescue the phenotype of a knockout zebrafish while WT and a negative control did. The authors suggest the first 2 variants are dominant negative while the latter three and loss of function.

The splice variant was shown to cause exon 7 skipping which is out of frame.

Transfection of the missense and splice variants in HEK293T cells showed that all but 1 had reduced TMEM184B protein levels.

Added comment: 1 month old baby with severe HCM found to have compound heterozygous variants in MYO19 (missense and frameshift). The patients mother, maternal aunt and maternal grandfather also had HCM and were diagnosed as teenagers or adults. The MYO19 frameshift variant was maternally inherited, but was not present in the affected aunt or grandfather.

MYO19 is a myosin located in the mitochondria, its role in cardiac function has not bene investigated.

All 4 affected individuals in this family also has variants in PHLPP2 (stop gain), CAPN1 (canonical splice) and ADAMTS8 (missense). CAPN1 is associated with biallelic HSP while the other 2 genes are not yet associated with disease. the CAPN1 and ADAMTS8 variants are present with over 10 hets in gnomad while PHLPP2 is absent.

It has previously been shown that inhibiting PHLPP2 activity increases cardiomyocyte hypertrophy.

Added comment: PMID 37915380: single individual with compound het variants in POLR3D and childhood onset leukodystrophy manifesting as DD/ID.

Additional neurological features included cerebellar signs (e.g., dysarthria, ataxia, and intention tremor) and dysphagia, while non-neurological features included hypodontia, hypogonadotropic hypogonadism, and dysmorphic facial features. Her MRI was notable for diffuse hypomyelination with myelin preservation of early myelinating structures, characteristic of POLR3-related leukodystrophy. Exome sequencing revealed the biallelic variants in POLR3D, a missense variant (c.541C > T, p.P181S) and an intronic splice site variant (c.656-6G > A, p.?). Functional studies of the patient's fibroblasts demonstrated significantly decreased RNA-level expression of POLR3D, along with reduced expression of other Pol III subunit genes. Notably, Pol III transcription was also shown to be aberrant, with a significant decrease in 7SK RNA and several distinct tRNA genes analyzed. Affinity purification coupled to mass spectrometry of the POLR3D p.P181S variant showed normal assembly of Pol III subunits yet altered interaction of Pol III with the PAQosome chaperone complex, indicating the missense variant is likely to alter complex maturation.

Review for gene: LDHD was set to GREEN
Added comment: 8 patients summarized in PMID: 40678184 with D-Lactate Dehydrogenase Deficiency. 5 homozygous missense, 1 homozygous frameshift, 1 compound heterozygous canonical splice and missense, and 1 homozygous deletion encompassing CTRB2, ZFP1 (neither of which have a disease association) and the first 7 exons of LDHD. Three of these patients had additional variants of interest in other genes that were thought to explain extra phenotypes they had out of the typical spectrum for this disorder.

Some patients only have increased plasma urate/gout however 4 also had delayed development, ataxia or epilepsy. 2 of these individuals had other genetic variants that likely explained the neurodevelopmental phenotype (11p deletion syndrome, CACNA1B), and 1 had the deletion that also affected 2 other genes of uncertain significance. So its unclear whether this gene is actually associated with a neurodevelopmental phenotype.

Mendeliome v1.3005 STAB2 Lucy Spencer changed review comment from: In a cohort of chronic thromboembolic pulmonary hypertension a missense in STAB2 was found in 2 related affected individuals. However, the variant Ala1665Thr is common on gnomad with over 100 hets and 4 homs. They also observed a significantly higher prevalence of 'qualifying alleles' in STAB2 in their disease cohort compared to the UK biobank- 4.6% in the disease cohort vs 1.2% in UK biobank. Qualifying alleles were rare and predicted deleterious. 78% of these variants were missense and quite a few of them also had thousands of hets and some homs in gnomad v4.

Phenotypic features
- age of onset 1.5-10 years old

The variants were noted to be rare in EXAC-East Asian cohort, most located in CUB/Sushi domains. The gene has some evidence of missense and LoF constraint in gnomAD v4. There was also enrichment of biallelic CSMD2 variants in affected individuals versus a control cohort of unaffected parents (5/420 compound hets affected individuals, 3/1942 compound hets in unaffected parents). Previous mouse Csmd2 knockdown models demonstrated reduction in dendritic spine density and complexity. LoF is the postulated disease mechanism.

Closely related gene paralog CSMD1 has a definitive association with autosomal recessive complex neurodevelopmental disorder with a more severe phenotype. Different expression profiles during developmental stages between CSMD1 and CSMD2 postulated for the comparatively milder phenotype associated with the latter.

Mendeliome v1.2977 CSMD2 Krithika Murali changed review comment from: PMID: 40632521 Li et al 2025 (Epilepsia) reported 6 unrelated individuals of Han Chinese descent with biallelic CSMD2 missense variants (NM_052896) and focal epilepsy. 5 individuals were compound heterozygous and one was homozygous. These individuals were ascertained through trio WES analysis of 420 unrelated individuals with focal epilepsy enrolled in the China Epilepsy Gene 1.0 project.

Phenotypic features
- age of onset 1.5-10 years old
- complex partial seizures (4), secondary GTCS (2)
- Normal MRI-B (3), focal cortical dysplasia (1)
- mild ID (1).

The variants were noted to be rare in EXAC-East Asian cohort, most located in CUB/Sushi domains. The gene has some evidence of missense and LoF constraint in gnomAD v4. There was also enrichment of biallelic CSMD2 variants in affected individuals versus a control cohort of unaffected parents (5/420 compound hets affected individuals, 3/1942 compound hets in unaffected parents). Previous mouse Csmd2 knockdown models demonstrated reduction in dendritic spine density and complexity. LoF is the postulated disease mechanism.

Closely related gene paralog CSMD1 has a definitive association with autosomal recessive complex neurodevelopmental disorder with a more severe phenotype. Different expression profiles during developmental stages between CSMD1 and CSMD2 postulated for the comparatively milder phenotype associated with the latter.

CSMD2 has 71 exons and 3631 amino acids. The true prevalence of biallelic missense variants in healthy individuals across diverse ancestries has not been ascertained. Review of the missense variants in this study highlighted issues in a number of them including poor-moderate conservation, conflicting or benign in silicos including REVEL, non-coding in an alternative transcript, Case 4 p.Val1547Ile homozygote – this variant has been noted in an East Asian male homozygote aged between 45-50.

Added comment: 3 individuals with biallelic variants identified as part of a large cohort (N=488) of women experiencing recurrent early embryonic arrest. These variants significantly altered protein length, abundance, or localization, resulting in spindle abnormalities in HeLa cells and mouse zygotes. Furthermore, the microinjection of exogenous mutant DLGAP5 mRNA into mouse zygote and the construction of Dlgap5 site-directed mutant mice successfully replicated the patient phenotypes. Functional studies, both in vivo and in vitro, revealed that DLGAP5 deficiency disrupts normal spindle assembly through its interaction with TACC3.

Added comment: Single individual reported with homozygous splicing variant c.403 + 3 A >T. Abnormal splicing demonstrated but leaky. Clinical features included pre and postnatal growth restriction, ventricular septal defect, dysmorphic features (proptosis, long eye lashes, thick eyebrows, low-set ears), microcephaly, sensorineural hearing loss, cortical cataracts, retinal defects, intellectual disability with limited speech, and autism spectrum disorder. Note mouse model is embryonically lethal, leading the authors to speculate survival may be due to fraction of normally spliced transcripts.

Added comment: preprint PMID 40385417, describing 12 individuals from 7 families with a spectrum of abnormalities (osteopetrosis not mentioned), suggestive of lysosomal disorder.

Homozygous loss-of-function variants presented with prenatally lethal arthrogryposis multiplex congenita, brain malformations, and neuropathological evidence of diffuse neuroaxonal dystrophy. Individuals with missense variants presented differently, with microcephaly, developmental epileptic encephalopathy, intellectual disability, optic atrophy, spasticity, and progressive movement disorders. In this group, brain MRI showed diffuse hypomyelination and progressive global cerebral atrophy, consistent with neurodegeneration. Borcs5 knockout in zebrafish exhibited microcephaly, motor deficits, and seizures, mirroring the patients' clinical presentation. At the cellular level, BORCS5 loss-of-function but not missense variants, resulted in lower protein expression and impaired BORC assembly, paralleled by perinuclear lysosomal clustering. However, both loss-of-function and missense BORCS5 variants were associated with reduced total lysosomal proteolysis, reduced activity of the lysosomal hydrolases glucocerebrosidase and cathepsin B, and presence of multilamellar bodies, indicating lysosomal dysfunction.

Added comment: CSMD3 encodes a synaptic membrane proteins and play a role in neuronal maturation/growth dendrites. A related protein CSMD1 has been previously associated with a complex neurodevelopmental disorder.

PMID: 40632521 describes 8 individuals with seizures. 4 with focal epilepsy, 3 with febrile seizures and 1 individual with infantile spasms. 1 individual described had a de novo missense variant with remainder having comp het/biallelic variants. Mild ID in 1 individual only.

Variant type mostly missense variants with 1 nonsense, all appropriately rare in gnomAD v4 for recessive disorder.

No variant specific functional studies performed, no clear discussion in paper about postulated mechanism for disease. No discussion around difference in mechanism for de novo monoallelic variant.

Previous studies showed homozygous knockout mice display abnormal neuronal proliferation and growth retardation.

Phenotypes for gene: ARNTL were set to Neurodevelopmental disorder, MONDO:0700092, BMAL1-related
Review for gene: ARNTL was set to GREEN
Added comment: Note has new HGNC approved name - BMAL1

BMAL1 encodes a transcription factor that plays a role in the mammalian molecular clock, binds to promoter of PER and CRY family genes to promote transcription. Other circardian genes have sleep phase disorder assoc but not neurodevelopmental phenotype.

10 affected individuals described in PMID: 40455867 with variable developmental delay/ID from average IQ to severe ID, seizures in 50%, autism, some had sleep disturbance and marfanoid habitus.
Variants were LOF & missense and very rare or absent in gnomAD v4.
5 confirmed de novo, 2 confirmed inherited (one from apparently unaffected mother).

Functional studies using luciferase reporter assay of downstream target PER showed reduced luminescence for most variants with presumed LOF mechanism. One variant p.(Ile201Thr) led to increased luminescence with author's postulating GOF mechanism for this variant. Drosophilia studies for 2 of the variants demonstrated altered circadian rhythm. ?needs more studies to further define mechanism.

Added comment: Heterozygous MAP4K1 loss-of-function variants were identified in two kindreds presenting with diverse immune dysregulatory symptoms, including recurrent fevers, inflammatory arthritis, EBV-related complications, and nephritis. Functional analysis of primary patient T cells, transcriptomics, and CRISPR-Cas9 editing demonstrated that HPK1 deficiency heightened T cell activation and inflammatory cytokine production. Penetrance was incomplete.

One of the families was multiplex (8 affected individuals) and the other had single individual affected, extensive functional data. Borderline Amber/Green.

Added comment: Bazex-Dupre-Christol syndrome (BDCS) is an X-linked dominant disorder characterized by a triad of congenital hypotrichosis, follicular atrophoderma affecting the dorsa of the hands and feet, the face, and extensor surfaces of the elbows or knees, and the development of basal cell neoplasms, including basal cell nevi and basal cell carcinomas from the second decade onward.

It is caused by small duplications in an intergenic region on chromosome Xq26 harbouring noncoding enhancer elements that drive overexpression of the ARHGAP36 gene.

Genomic coordinates (GRCh38) : X:129,500,001-138,900,000.

At least 9 families reported but AMBER rating until we decide how to handle regulatory region information in PanelApp Aus -- coding region variants not reported.

Parentage not confirmed in 3. Two had other possible variants of interest.

Used Xenopus to investigate the effect of one of the missense variants, S230W, and demonstrated activation of the Raf-MEK-Erk pathway and embryonic defects when expressed at high levels. Suggests GoF as mechanism.

Further de novo missense identified in a large cohort of NDDs, PMID 35143101.

PMID 35501409: knockout Zebrafish, altered brain activity and behaviour.

PMID 22124272, 26207352: two mouse models also support role in brain development.

MODERATE by ClinGen, but note this is mostly driven by experimental data points.

Cohort of 11 individuals all with a history of motor and/or language developmental delay, intellectual disability in 6/11 (mild to severe), brain structure/function abnormalities were reported in 9/11 patients (7/11 seizures; 5/9 abnormal findings on brain MRI), muscle weakness/hypotonia in 8/9, psychosis in 4/10 patients, symptoms of catatonia in 4/10, other psychiatric/behavioural concerns (anxiety, attention deficit, autism or autistic features) in 10/10.

Total of 10 variants including 2x frameshift/nonsense, 6x missense, 1x splice, 1x single amino acid deletion – all absent from v4 and de novo except 1 inherited from a father with cognitive and psychiatric symptoms and the inframe del which has 2 hets in gnomAD and is inherited an unaffected father (no formal assessment).

In vivo zebrafish modelling measuring cilia length suggests that patient variants tested (9/10 excluding the splice variant) did not induce cilia length shortening, which is consistent with KO models and therefore a loss of function effect.

11 individuals from seven unrelated families (includes 4 individuals from 3 families described in Bertoli-Avella PMID: 33875846), with severe neurodevelopmental disorder and harbour biallelic variants of BLOC1S1.

The disorder presents with early infantile onset and is characterised by deficient myelination, global developmental delay, intellectual disability, hypotonia, epilepsy), and visual impairment (bilateral optic atrophy in most). The severity ranged from early death to a milder form with preserved ambulation and single-word communication. All individuals harbouring BLOC1S1 variants with available neuroimaging exhibit hypomyelinating leukodystrophy.

Functional analyses show that BLOC1S1 KO impairs the anterograde transport of lysosomes and autophagy in both non-neuronal cells and iPSC-derived neurons. Missense variants displayed various combinations of defective expression, assembly, lysosome dispersal and/or autophagy. The frameshift variant showed the most severe deficiencies in tested assays.; to: De Pace et al. 2025 [preprint] doi: https://doi.org/10.1101/2025.07.17.25331211

Added comment: 4 fetuses (TOP/deceased) from 4 consanguineous unrelated families with a clinical diagnosis of Meckel-Gruber syndrome. Clinical features includes: encephalocele (4/4), enlarged/cystic kidneys (4/4), and postaxial polydactyly (1/4). WES identified 3 homozygous variants (p.(Glu2Serfs*58); p.(Pro123Thrfs*9); and p.(Pro123Arg)).

They also reported a 5th consanguineous family with 3 affected fetuses with clinical diagnosis of Meckel-Gruber syndrome. Both parents were heterozygote carriers of a TMEM17 variant (p.(Glu2Serfs*58)) but biological material from the fetuses was not available.

No functional studies performed. However, TMEM17 is a critical component of a protein complex in the basal body at the base of cilia. Knockdown of Tmem17 via small interfering RNA has been shown to have a modest effect on cilia formation, but significantly reduces the amount of the somatostatin receptor Sstr3 (182453) that localizes to cilia.

Added comment: cohort of 9 patients with moderate to profound ID, microcephaly, seizures (7/9), facial dysmorphism, and brain malformations (6/9 - corpus callosum hypoplasia, Dandy-Walker malformation).

3 splice, 1 frameshift, 2 missense, 3 in frame deletions, 1 start loss. all but 1 de novo (the last parents not available).

SNW1 is a core component of the spliceosome and facilitates the conformational changes of the spliceosome. Expression of variants in HEK293 cells showed some decreased SNW1 expression while others increased it (including the frameshift), and only the frameshift variant was mislocalised/in the cytoplasm instead of the nucleus. Several of the variants caused loss of binding to PPIL1 or other proteins which SNW1 usually recruits to the spliceosome. All variants in this study were found to either affect protein expression or localization or influence interactions with other proteins in the spliceosome complex suggesting loss of function.

7 affected individuals from 6 families described in PMID: 40619738 with congenital heart disease (ASD, VSD, hypoplastic left heart). 4 cases had de novo variants in SMAD5 with some cases having inheritance from presumably unaffected parents (however parents weren't formally assessed). All variants absent from gnomAD v4.

Supportive functional studies with transfection into HEK293T cells showing reduced SMAD5 levels and luciferase promoter assay showing reduced promoter activity of downstream targets with rescue upon introduction of WT SMAD5. LOF mechanism proposed. Variants were missense/nonsense/frameshift/large del.

One individual presented with a more severe multi system phenotype including tetralogy of fallot, craniofacial/urogenital/renal/limb/vertebral anomalies with a variant that was proposed to act in a dominant negative manner.

Mendeliome v1.2797 AMFR Zornitza Stark edited their review of gene: AMFR: Added comment: PMID 38277122:

Single case report of 3-year-old boy in whom varicella followed a complicated course with thrombocytopenia, haemorrhagic and necrotic lesions, pneumonitis, and intermittent encephalopathy. HLH was the working diagnosis. Although the clinical condition improved, longstanding hemophagocytosis followed despite therapy.

Rare monoallelic variant in autocrine motility factor receptor (AMFR) identified. AMFR encodes a ubiquitin ligase involved in innate cytosolic DNA sensing and interferon (IFN) production through the cyclic GMP-AMP synthase-stimulator of IFN genes (cGAS-STING) pathway.

Peripheral blood mononuclear cells (PBMCs) from the patient exhibited impaired signaling downstream of STING in response dsDNA and 2'3'-cGAMP, agonists of cGAS and STING, respectively, and fibroblasts from the patient showed impaired type I IFN responses and significantly increased VZV replication. Overexpression of the variant AMFR R594C resulted in decreased K27-linked STING ubiquitination compared to WT AMFR. Moreover, ImageStream technology revealed reduced STING trafficking from ER to Golgi in cells expressing the patient AMFR R594C variant. This was supported by a dose-dependent dominant negative effect of expression of the patient AMFR variant as measured by IFN-β reporter gene assay. Finally, lentiviral transduction with WT AMFR partially reconstituted 2'3'-cGAMP-induced STING-mediated signaling and ISG expression in patient PBMCs. This work links defective AMFR-STING signaling to severe VZV disease and hyperinflammation and suggests a direct role for cGAS-STING in the control of viral infections in humans.

The patient had a history of haematologic abnormalities and viral-associated complications, including chronic macrocytosis, persistent vaccine-strain rubella granulomas, and EBV-associated Hodgkin lymphoma. Immunophenotyping revealed loss of B cells, hypogammaglobulinemia, and impairments in cytotoxic T and NK cell populations. T cells exhibited skewing toward an exhausted memory phenotype, global DNA methylation loss, and increased epigenetic aging. These aberrations were ameliorated by wild-type ASXL1 transduction.

Note mono allelic variants are associated with Bohring Opitz syndrome and somatic variants are associated with clonal haematopoiesis.

Added comment: 24 individuals from 12 families reported with severe, acute-onset axonal neuropathy following infection (13 female and 11 male patients, with a mean age at diagnosis of 1 year 10 months [SD 2·27]).

Eight biallelic missense variants in RCC1 identified.

Patients had variable phenotypes, ranging from rapidly progressive fatal axonal neuropathy to mild motor neuropathy with impaired walking. Neurological presentation was often secondary to an infection, resulting in initial misdiagnoses of Guillain-Barré syndrome in several patients. 15 children had disease recurrence. The disease was fatal in 15 patients.

The RCC1 variants coded for proteins that alter GDP-to-GTP exchange activity and had reduced thermal stability in vitro. In primary fibroblasts, heat shock or oxidative stress revealed defects in Ran nuclear localisation and impaired nucleocytoplasmic transport. A Drosophila model of the disease revealed a fatal intolerance to oxidative stress.

- ZNF597 is highly expressed in the placenta and proposed to have an important role in placental development.
- Knockout ZNF597 mice (homozygous -/-) is embryonic lethal due to failed embryonic organization before cardiogenesis at embryonic day 7.5. This period is equivalent to human Carnegie Stage 9 that occurs during week 3 between 19 to 21 days (5 weeks' gestation).
- Literature associated with ZNF597 including maternal uniparental disomy of chromosome 16 (UPD(16)mat) or loss of paternal imprinting of ZNF59, resulting in an overexpression of ZNF597.
- Unpublished in-house data/observation: A heterozygous deletion with a breakpoint in ZNF597 was observed in the female partner of a couple experiencing x4 early pregnancy loss at 5-8 weeks' gestation.

The TIMP2 disruption in miscarriages in Family 6 may have affected the placental development, but the possibility remains that maternal disruption of TIMP2 may contribute to RPL by impairing the remodeling of the endometrium in early pregnancy. Functional study was performed by PMID: 25674159, which showed reduced RNA and protein expression in chorionic villi cultures from miscarriages with the CNV.

ii) PMID: 33966269- Homozygous missense mutation p.C299R in two infertile sisters with oocyte maturation arrest and degeneration from a consanguineous family. Functional assays showed that the transcriptional level of ZP3 was not completely blocked but severely reduced by the regulation of the mutant TBPL2, while the transcriptional level of H2Bc was significantly reduced but to a less severe extent compared with that of ZP3, suggesting that the missense had a damage to the transcription initiation function of TBPL2 and its downstream targeted genes got involved in different degrees. The mutant protein also has less stability, which contributes to the lower activity of transcription initiation in the mutant form.

iii) PMID: 33893736- Homozygous splicing variant (c.788 + 3A>G) in two unrelated families characterized by oocyte maturation defects. Functional assays showed that the variant disrupted the integrity of TBPL2 mRNA and affected oocytes showed that vital genes for oocyte maturation and fertilization were widely and markedly downregulated, suggesting that a mutation in TBPL2, led to global gene alterations in oocytes; the same variant reported before in PMID: 33541821 in three affected females with diminished ovarian reserve from 3 independent families.

Added comment: PMID: 38060382- Compound heterozygous variants (p.Cys428Profs∗28/p.Leu887delinsArgTyr) reported in an infertile woman with oocyte maturation defects and early embryo arrest (EEA).
- Functional analysis showed comparable protein levels compared with the wild-type control, although a truncated band of the expected size (47 kDa) was observed for the p.Cys428Profs∗28 variant.
-The truncated variant, p.Cys428Profs∗28, is lacking the LRR domain and, hence, completely loses the ability to bind with UHRF1. The p.Leu887delinsArgTyr variant results in significant alteration in binding modes with decreased binding area and binding free energy, which introduced regional instability in the NLRP14-UHRF1 interaction. The interaction of both variants and UHRF1 was disrupted and might lead to increased UHRF1 protein degradation in oocytes.

Her arrested embryos from MEI1-affected oocytes exhibited abnormalities in copy number variation and DNA methylation following CMA, which contrasts with the proliferating embryos secondary to the loss of maternal chromosomes in hydatidiform moles.

ii)PMID: 34037756- five novel mutations in MEI1 in nine patients with similar infertile phenotypes of recurrent hydatidiform moles, embryonic arrest, recurrent implantation failure, and recurrent pregnancy loss from seven independent families. In vitro studies also demonstrated that protein-truncating and missense mutations reduced the protein level of MEI1, while the splicing mutations caused abnormal alternative splicing of MEI1.

New papers (biallelic variants for NOA):
i) PMID: 36759719- Biallelic deleterious variants in four Chinese patients with NOA. Testicular pathologic analysis and immunohistochemical staining revealed that spermatogenesis is arrested at spermatocyte stage, with defective programmed DNA double-strand breaks (DSBs) homoeostasis and meiotic chromosome synapsis in patients carrying the variants. In addition, our results showed that one missense variant (c.G186C) reduced the expression of MEI1 and one frameshift variant (c.251delT) led to truncated proteins of MEI1 in in vitro.

MAJIN codes for a junction protein that forms a complex with TERB1 and TERB2, which together bind to telomeres and anchor them to the inner nuclear membrane components KASH5 and SUN1. This attachment of chromosomes to the nuclear envelope is essential for homologous chromosome movement and synapsis. In mice, both male and female null mutants Majin are infertile (PMID: 26548954). In humans, biallelic mutations in MAJIN have been reported in infertile males.

In vitro assays revealed they had a functional effect as they led to perturbations in FOXD1 transactivation properties on promoters of the Placental Growth Factor (PGF) and the complement component gene (C3) having key roles during implantation/placentation.

ii) PMID: 31395028- 9 heterozygous non-synonymous variants in patients affected by PE, IUGR, RPL and repeated implantation failure (RIF) , two of which (p.His267Tyr found in one RIF patient and p.Arg57del in one IUGR woman) represented novel and coherent candidates for in vitro testing. Functional experiments revealed that both led to an increased C3 (complement C3) promoter transcriptional activity. Also found increased FOXD1-p.Arg57del variant transactivation capacity on the PlGF (placental growth factor) promoter.The FOXD1 p.Ala356Gly and p.Ile364Met variants (previously found in RPL patients in PMID: 27805902) have also been identified in the present work in women with PE and IUGR and with isolated IUGR, respectively.

Relative expression levels of CDC25A were about 2.5-fold lower in azoospermic testicular tissue and semen samples, reflecting diminished transcriptional activity in affected patients. This reduction in gene expression may reflect a potential functional deficiency of CDC25A, contributing to spermatogenic arrest. The decreased level of CDC25A mRNA levels corresponds with the findings of pathogenic variants identified in azoospermic patients, thus solidifying the evidence of CDC25A mutations contributing to male infertility.

ii) PMID: 30009144,16720623- decreased expression of CDC25A observed in testicular biopsies from azoospermic men, suggesting association with meiotic arrest as the etiology of spermatogenic failure.

- The I126T mutation in CCP2 of C4BP α-chain is of particular interest as it was found only in one patient but not in healthy controls. This rare mutation affected both expression level of C4BP α-chain as well as its function, i.e., degradation of C4b and C3b in solution.
R120H, found in two patients and no controls, increased the ability of C4BP to act as cofactor in degradation of C4b but decreased its activity in degradation of C3b both in solution and deposited on the cell surface. The other 2 variants have been observed in controls.
- Homozygous C4BP knockout mice often die during second or third pregnancy (unpublished observation). This would imply a pivotal role of this protein in maintenance of successful pregnancy, although the mechanism is not known.

i) PMID: 38342987- novel hemizygous nonsense variant (c.1564G > T:p.Glu522*) in a male patient with oligoasthenoteratozoospermia (OAT) from a Han Chinese family. Functional analysis showed that the variant produced a truncated protein with altered cellular localization and a dysfunctional interaction with SKP1 (S-phase kinase-associated protein 1).

They hypothesized that the BCORL1 (c.2615 T > G, c.2669G > A, c.3164A > G, c.3344C > T) missense mutations may have led to an accumulation of dysfunctional toxic proteins that resulted in a more severe male infertility phenotype in the patient (NOA).

Added comment: 3 unrelated individuals with Leigh syndrome (1 x severe/early-onset/fatal, 1 x milder/childhood-onset, 1 x adult-onset). WES identified compound heterozygous variants in FASTKD5 gene (3 x missense variants, 2 x frameshift variants leading to a premature stop codon). The FASTKD5 gene codes for a mitochondrial protein essential for processing mRNAs at non-canonical cleavage sites in the primary mitochondrial transcript.

Analysis of fibroblasts from two subjects showed reduced steady-state levels of FASTKD5 protein by immunoblot, reduced translation of the cytochrome c oxidase subunit 1, impaired assembly of complex IV, and a consequent decrease in cytochrome c oxidase enzymatic activity. The extent of these deficiencies appeared to correlate with the severity of the clinical phenotype. Expression of a wild-type FASTKD5 cDNA, but not cDNAs expressing the missense variants, rescued all the molecular defects in the subjects' fibroblasts, demonstrating that the alleles are pathogenic. 2/3 missense variants resulted in near complete loss of function, while one was hypomorphic, resulting from impaired protein stability.

Mendeliome v1.2697 BHLHA9 Sarah Milton changed review comment from: BHLHA9 encodes a transcription factor involved in embryonic limb development, essential for interdigital apoptosis in central limb mesenchyme cells.

Duplications encompassing a 11.8kb critical region involving BHLHA9 have been reported in a number of publications to result in split hand foot malformation with long bone deficiency in at least 50 affected individuals. This has segregated within families of affected individuals on a number of occasions.

Review for gene: PDCD2 was set to AMBER
Added comment: PMID: 40208938- Novel biallelic PDCD2 variants associated with hydrops fetalis and early pregnancy loss in two affected families. Family 1 with RPL had three fetuses with NIHF who were all homozygous for p.(Pro28Ser) in PDCD2, while Family 2 had p.(Pro28Ser) in trans with p.(Arg34Pro) in two fetuses with NIHF. Family 2 was additionally notable for having a healthy child who was homozygous for the reference allele, consistent with appropriate disease segregation with the PDCD2 variants. Functional studies using primary fetal fibroblasts and human cell lines for both variants showed reduced PDCD2 mRNA level in affected patients' fibroblasts, reduced cellular accumulation of mutant proteins with impaired ability to associate with the 40S subunit ribosomal protein uS5, and further depletion of PDCD2 in fibroblast cells severely impacted ribosome biogenesis. It is notable that formation of the PDCD2-uS5 complex was not completely abolished by the patient variants and that rRNA processing was only partially impaired, as indicated by levels of 40S pre-rRNAs. We thus suspect that the PDCD2 pathogenic variants p.(Pro28Ser) and p.(Arg34Pro) are hypomorphic alleles, with a low level of residual function allowing for cellular differentiation and growth to a certain extent.

Phenotypes for gene: RPL17 were set to Diamond-Blackfan anemia, MONDO:0015253
Review for gene: RPL17 was set to GREEN
Added comment: PMID:39088281 reported two different pedigrees identified with monoallelic variants in RPL17 gene (3C>G & c.452delC/ p.(Thr151Argfs*25). Affected individuals from both pedigrees exhibited clinical features and erythroid proliferation defects consistent with Diamond-Blackfan anaemia. Individuals from first family also presented with skeletal abnormalities, which were not reported in family 2. Modelling of rpl17 deficiency in zebrafish recapitulated the major clinical features of the disorder including anaemia and micrognathia. There is also functional evidence available from lymphoblastoid cell lines (LCLs) derived from patients, which displayed a ribosomal RNA maturation defect reflecting haploinsufficiency of RPL17.

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

Carbonell (PMID: 31388001) - reports deletions in seven families. Five of these families carry frameshift deletions predicted to undergo NMD. While there are two shorter transcripts for the gene (AIDA-1C and AIDA 1D), the short isoforms showed reduced transcription similarly to the long isoform (AIDA-1B, MANE NM_001352186.2) - as tested in probands compared to their mothers who were unaffected and not carriers of the deletions.

Hoon Cho (PMID: 38129387) - presents five additional ANKS1B deletion patients. They list the variants as multigenic although they appear to only affect ANKS1B. The patients are listed to have neurodevelopmental syndrome and white matter/corpus callosum abnormalities on MRI. One of the five carries a frameshift deletion (35 year old male). Note: the nine patients listed at the top of Figure 1 are from Carbonell. Paper includes supportive mouse studies.

Added comment: 12 patients from 11 families with phenotype characterised by subacute loss of skills following initially normal development, spastic dystonia, bulbar involvement, preserved head circumference, and an absence of seizures. The observation of enhanced type 1 IFN signalling in patient blood and CSF, and of increased levels of CSF neopterin suggests that PTPN1 haploinsufficiency can be classified as a novel type 1 interferonopathy. Features apparently distinguishing PTP1B-related encephalopathy from Aicardi-Goutières syndrome are a later age at onset (nine of 12 cases in cohort presenting beyond 18 months of age), notable bulbar involvement manifesting as difficulties with swallowing and expressive speech, and cerebral atrophy as the predominant neuroradiological sign.

Added comment: Encodes substrate recognition component of SCF E3 ubiquitin ligase complex. Has role in post translational ubiquitination and degradation of certain substrates e.g. histone demethylases.

14 cases from 12 families published with affected individuals noted to have homozygous frameshift variants (FBXO22:c.159_162del,c.8_36del,c.719_722del - all rare/absent gnomad v4).

Phenotype included prenatal growth restriction/short stature, neurodevelopmental delay, microcephaly, hypotonia, seizures, craniofacial dysmorphisms (high forehead, depressed nasal bridge, hypertelorism), variable additional findings including cardiovascular and gastrointestinal anomalies.

Supportive functional studies - FBXO22 is involved of degradation of KDM4B, KDM4B protein levels in one affected individual were found to be higher than control. Unique genome wide episignature identified for FBXO22 in 3 individuals with the disorder (given loss of this protein results in increased levels of various histone demethylases).

3 papers detail 10 affected individuals from 6 families with either a homozygous recurrent splice variant (LSM1:c.231+4A>C) or a homozygous missense variant (LSM1:p.Asn40Tyr in only 1 family). Both very rare in gnomad v4 with 0 homozygotes.

The phenotype of the individuals encompassed severe intellectual disability/developmental delay, shared dysmorphic features (broad forehead, pointed chin, medially thickened arched eyebrows, hypertelorism, bulbous nasal tip), skeletal anomalies, cardiovascular (ASD/VSD/aortic valve) and genitourinary abnormalities (CAKUT/hypospadias), gastrointestinal manifestations, hypotonia and visual impairments.

RT PCR of the splice variant demonstrated exon 3 skipping with a resultant truncated protein with presumed loss of function mechanism. It was noted by authors there are no biallelic loss of function variant in the gnomad v4, as such it was suggested complete loss of function is non viable.

Added comment: 18 individuals from 10 unrelated cerebellar ataxia families were heterozygous for a RAB3A missense variant. 9/10 families had a recurrent variant - p.Arg83Trp. The age of onset of the ataxia was adult, except for 3 paediatric/adolescent onset cases. Additionally, 4 individuals from 3 families (F11, F12, F13) with 2 de novo missense and a stopgain had similar phenotypes consisting of a neurodevelopmental syndrome with progressive cognitive deficits and spasticity. F14 was a singleton with a missense variant and HMSN & optic atrophy. Initially included in the cohort for gait ataxia, was found to be a sensory ataxia. There were supporting in vitro functional assays and Drosophila rescue models that suggest partial loss of function as the disease mechanism, but were unable to differentiate the genotype-phenotype correlation for the cerebellar ataxia phenotype vs the neurodevelopmental syndrome.

Four individuals with global DD, microcephaly, and short stature. Three out of the four individuals had the recurrent homozygous EIF3K (Asp43Gly - gnomAD v4.1 GrpMax FAF - 0.06044%) variant whilst another individual has homozygous intronic EIF3K variant, c.355-13A>G (gnomADv4.1 GrpMax FAF = 0.002551%).
The 3 individuals of Puerto Rican ancestry with the recurrent missense variant also had homozygous SYNE4 variant (Arg119Trp) identified which the author related to the probands' hearing loss phenotype.
The Asp43Gly missense variant could potentially be a founder variant however only three families with affected probands have been reported with the variant.

ClinGen's reason for disuputed classification - "Case-level data was not considered strong enough to score. Functional data was not consistent among the variants and was difficult to interpret in relationship to a seizure phenotype. The knock-out mouse model did not exhibit spontaneous seizures so was not scored."

Added comment: PMID:29555651 reported a family with four consecutive cases of late foetal loss with gestational ages between 17 and 35 weeks. The foetuses showed prenatal abnormalities including intrauterine growth restriction (IUGR), microcephaly, craniofacial anomalies, sex reversal in male foetuses, and congenital heart defects. A homozygous inactivating variant in SIRT6 gene (c.187G > C; p.(Asp63His)) was identified by WES in the four foetuses. There is also functional data available from in vitro studies, SIRT6 D63H mouse embryonic stem cells and human induced pluripotent stem cells (iPSCs) derived from D63H homozygous foetuses.

There is also functional evidence available from several other studies including PMID:30135584, where CRISPR-Cas9-based approach was used to generate a SIRT6-null cynomolgus monkey (Macaca fascicularis) model. SIRT6-deficient monkeys died hours after birth and exhibited severe prenatal developmental retardation.

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

Added comment: Two unrelated probands with multiple congenital anomalies, both with abnormalities of the cardiovascular system and confirmed de novo novel missense variants (p.R248Q and p.N169S). There were also additional individuals (<5) in the GeneDx in-house database who didn’t consent to case-level publication with confirmed de novo missesne variants in KCTD10 and overlapping phenotypes (100% with abnormalities of the cardiovascular system). Other congenital anomalies of different organs systems were present in 33-67% of the individuals. Further elucidation of the phenotypes associated with this gene are required. Additionally, null mouse and zebrafish models suggest Kctd10 is critical for cardiovascular development and is involved in the regulation of brain development.

ii) PMID: 32938693- homozygous missense variant (p.V1251D) in two sisters with RPL and two of their POCs were characterised and found to be triploid digynic due to the failure of meiosis II.
iii) PMID: 34021051- novel homozygous frameshift variant (p.Val1321Glyfs*4, due to splicing causing exon skipping) in a patient with 16 RPL and one of her miscarriages is triploid digynic resulted from the failure of meiosis I.

Supporting mouse evidence:
iv) PMID: 30770433- Ccnb3 knockout also causes female infertility due to the failure of metaphase to anaphase transition in meiosis I and the extrusion of the first polar body. The infertility in these mice appeared to be due to embryonic lethality before embryonic day 7.5 and some of their oocytes fertilised by intracytoplasmic sperm injection led to triploid embryos.
v) PMID: 34850816- Ccnb3-deficient mouse model is similar to a human infertility condition—recurrent pregnancy loss (RPL). Their findings demonstrate that the triploidy of embryos derived from Ccnb3-deficient oocytes is the primary cause of embryo death (i.e., such embryos can be rescued with euploid nuclei, whereas cytoplasmic Ccnb3 transcript is dispensable for zygotic genome activation and embryo development).

(CDKL5 has been associated with a neurodevelopmental disorder previously.)

Bereshneh et al describe 2 individuals with a neurodevelopmental disorder with de novo variants in CDKL1 sourced from databases containing individuals with neurodevelopmental disorders, no additional phenotypic information was provided. Both variants were missense and present in the population (c.505C>T - 13 heterozygotes in gnomad 4, c.344T>C - 2 heterozygotes gnomad 4).

Both missense variants were located in the kinase domain and dominant negative mechanism was postulated based on drosophilia studies.

Functional studies in drosphilia showed variants seen in probands partially rescued a loss of function model however overexpression of transcripts containing the variants resulted in a more severe phenotype suggesting dominant negative.
Authors also noted the larger than expected number of LOF variants in gnomad for the disease to be caused by this mechanism.

iii) PMID: 35547809- A heterozygous missense variant (p.Cys24Ter) in the male partner of a patient couple, who had a previous fertilization failure (FF) after intracytoplasmic sperm injection (ICSI) and became pregnant after ICSI together with artificial oocyte activation (AOA). Their Septin12 knockout mice study also showed that Septin12 -/- male mice are infertile with reduced sperm counts and abnormal sperm morphology but male Septin12 +/− mice are fertile. This observation contradicted with the previous studies showed that male Septin12 +/− chimeric mice are infertile (Lin et al., 2009, PMID: 19359518). The main difference is that the Septin12 +/− chimeric mice were generated in Lin et al., 2009 (PMID: 19359518) was by blastocyst injection of Septin12 +/− embryonic stem cells (ESCs), while their Septin12 +/− founder mice were established by CRISPR/Cas9 mediated gene editing in the zygote. The quality of injected Septin12 +/− ESCs might affect the experimental result.

ID was moderate in two of them, while IQ was normal in one. There is also functional evidence available for these variants.

PMID:39758889 reported the identification of a novel heterozygous de novo frameshift variant in CRMP1 (p.(Lys586fs)) in a 9-year-old male patient presenting with phenotypes such as autism, language delay, hyperactivity, and learning disabilities. This patient was reported with moderate ID.

There are three unrelated cases reported with moderate intellectual disability and with monoallelic CRMP1 variants. However, one patient with a different monoallelic CRMP1 variant had normal IQ. Hence, this gene should be rated amber with current evidence.

Added comment: SLC25A25 encodes mitochondrial ATP-Mg/Pi carrier 3

A single missense variant was reported in 2 families with renal stones in 2021 by Jabalameli et al (PMID: 3436195).
In family 1 there was 4 affected individuals who shared the same heterozygous variant NM_001330988.2 c.1083G>C|p.Gln361His, however this variant was also seen in 7 individuals in the family without stones
In family 2 there were 7 affected individuals who also had p.Gln361His however this variant was also seen in 3 family members without stones.

This variant is located within the mitochondrial carrier domain and functional studies were performed looking at uptake of radioactive ATP compared to wild type. These studies demonstrated the variant protein had approximately 21% activity compared to wild type.

The variant was proposed to have incomplete penetrance and it should be noted there is 4352 heterozygotes in gnomad 4.

At this time there is insufficient evidence for a gene disease association between SLC25A25 and nephrolithiasis.

Added comment: One 20yrs old individual with learning issues, motor coordination disorders, hypotonia (myopathy on EMG), and behavioural issues (mood and emotional dysregulation). WES testing identified a de novo heterozygous missense variant (Glu191Lys) in PPP2R5E gene. The variant was not found in the 4 healthy brothers of the individual. The variant is located within a conserved LFDSEDPRER motif common to all PPP2R5 B-subunits. Biochemical assays demonstrated a decreased interaction with the PP2A A and C subunits, leading to disturbances in holoenzyme formation.

Protein phosphatase 2A (PP2A) is a family of multifunctional enzymatic complexes crucial for cellular signalling, playing a pivotal role in brain function and development. Mutations in specific genes encoding PP2A complexes have been associated with neurodevelopmental disorders with hypotonia and high risk of seizures (e.g. PP2AR-1A, 2B, 3C, 5C, 5D).

They were all undergoing treatment for hypertension, had mean eGFR of ~31, None of them had any liver cysts or any family history of cystic kidney disease. WGS after negative clinical diagnostic testing, identified 3 missense variants in CFAP47 gene [p.(Arg870Gln), p.(Phe516Cys), and p.(Gly6Asp)]. The variants were rare in gnomAD but had equivocal in silico prediction scores, and would be reported as VUS using ACMG criteria. Segregation was not possible as their mothers were deceased. CFAP47 encodes cilia and flagella associated protein 47 a protein that plays a role in the formation and function of cilia and flagella. It is is expressed in primary cilia of human kidney tubules. Knockout (KO) mice exhibited larger kidneys with vacuolation of tubular cells and tubular dilation, providing evidence that CFAP47 is a causative gene involved in cyst formation.; to: 3 Japanese individuals with bilateral kidney cysts with mild enlargement of kidneys (mean age at Dx ~70yrs).

Added comment: 4 unrelated cases with a recurrent post-zygotic GNA13 variant (NM_006572.4:c.599G>A p.Arg200Lys) with a syndrome including hypomelanosis of Ito associated with developmental anomalies. The variant was identified in one patient via exome sequencing of paired tissue/blood and then targeted GNA13 testing of other cases. In vitro assays demonstrate a gain of function for the variant. Q226L was an artificial variant demonstrating a gain of function similar to R200K. The suggested mechanism of disease is through upregulation of the RHOA/ROCK pathway altering melanocyte function.
