Variant summary

Our verdict is Pathogenic. Variant got 5 ACMG points: 5P and 0B. PM2_SupportingPM3PP3PP4

This summary comes from the ClinGen Evidence Repository: The c.11713C>T variant in USH2A is a missense variant predicted to cause substitution of arginine by cysteine at amino acid 3905 (p.Arg3905Cys). The highest population minor allele frequency in gnomAD v4 is 0.007% (6/75036) in the African / African American population, which meets the ClinGen Hearing Loss VCEP threshold (≤0.007%) for PM2_Supporting. The computational predictor REVEL gives a score of 0.8, which is above the threshold of 0.7, evidence that correlates with impact to USH2A function (PP3). This variant has been detected in at least 6 individuals with Usher syndrome and at least 4 individuals with inherited retinal dystrophy. Of those individuals, 1 was homozygous and 7 were compound heterozygous for the variant and a pathogenic or likely pathogenic variant. At least 1 of those were confirmed in trans by family testing (PM3_VeryStrong, PMID:31877679, 25333064, 28559085, 24944099, 34781295, 36011402, 32531858, 36909829, 27208204, 37217489). At least one patient with this variant was diagnosed with Usher syndrome, which is highly specific for USH2A-related disorders (PP4, PMID:31877679). In summary, this variant meets the criteria to be classified as Pathogenic for autosomal recessive Usher syndrome based on the ACMG/AMP criteria applied, as specified by the ClinGen Hearing Loss Expert Panel: PM2_Supporting, PP3, PM3_VeryStrong, PP4.

Genes affected
USH2A (HGNC:12601): (usherin) This gene encodes a protein that contains laminin EGF motifs, a pentaxin domain, and many fibronectin type III motifs. The protein is found in the basement membrane, and may be important in development and homeostasis of the inner ear and retina. Mutations within this gene have been associated with Usher syndrome type IIa and retinitis pigmentosa. Multiple transcript variants encoding different isoforms have been found for this gene.

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 25333064, 24944099, 28559085, 27208204, 34781295, 33576794, 32531858, 31877679) -

Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 3905 of the USH2A protein (p.Arg3905Cys). This variant is present in population databases (rs368675850, gnomAD 0.005%). This missense change has been observed in individual(s) with Usher syndrome (PMID: 24944099, 25333064, 27208204, 28559085). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 236537). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. For these reasons, this variant has been classified as Pathogenic. -

Variant summary: USH2A c.11713C>T (p.Arg3905Cys) results in a non-conservative amino acid change located in the Fibronectin type III domain (IPR003961) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 2.4e-05 in 247752 control chromosomes. c.11713C>T has been reported in the literature as a compound heterozygous genotype in multiple comprehensively genotyped individuals affected with Usher Syndrome (example, Ellingford_2016, Stone_2017, Weisschuh_2020). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (P/LP, n=3; VUS, n=2). Based on the evidence outlined above, the variant was classified as pathogenic. -

The c.11713C>T variant in USH2A is a missense variant predicted to cause substitution of arginine by cysteine at amino acid 3905 (p.Arg3905Cys). The highest population minor allele frequency in gnomAD v4 is 0.007% (6/75036) in the African / African American population, which meets the ClinGen Hearing Loss VCEP threshold (≤0.007%) for PM2_Supporting. The computational predictor REVEL gives a score of 0.8, which is above the threshold of 0.7, evidence that correlates with impact to USH2A function (PP3). This variant has been detected in at least 6 individuals with Usher syndrome and at least 4 individuals with inherited retinal dystrophy. Of those individuals, 1 was homozygous and 7 were compound heterozygous for the variant and a pathogenic or likely pathogenic variant. At least 1 of those were confirmed in trans by family testing (PM3_VeryStrong, PMID: 31877679, 25333064, 28559085, 24944099, 34781295, 36011402, 32531858, 36909829, 27208204, 37217489). At least one patient with this variant was diagnosed with Usher syndrome, which is highly specific for USH2A-related disorders (PP4, PMID: 31877679).

The USH2A c.11713C>T variant is predicted to result in the amino acid substitution p.Arg3905Cys. This variant has been reported in the homozygous and compound heterozygous state in patients with retinal disorders or Usher syndrome (Baux. 2014. PubMed ID: 24944099; Krawitz. 2014. PubMed ID: 25333064; Ellingford. 2016. PubMed ID: 27208204; Stone. 2017. PubMed ID: 28559085; Karali. 2019. PubMed ID: 31877679; Colombo. 2021. PubMed ID: 33576794; Colombo. 2021. PubMed ID: 34781295). This variant is reported in 0.0050% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-215901725-G-A). This variant is interpreted as likely pathogenic. -
