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.

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 3267 of the USH2A protein (p.Cys3267Arg). This variant is present in population databases (rs111033263, gnomAD 0.006%). This missense change has been observed in individual(s) with Usher syndrome or isolated retinitis pigmentosa (PMID: 17085681, 22004887, 25404053, 30190494). 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: 48634). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt USH2A protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Predicted Consequence/Location: Protein truncation variants are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.78; 3Cnet: 0.63). The same nucleotide change resulting in the same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000048634 /PMID: 17085681). Different missense changes at the same codon (p.Cys3267Phe, p.Cys3267Trp) have been reported to be associated with USH2A related disorder (ClinVar ID: VCV001006654 /PMID: 25356976). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
