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.

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 3618 of the USH2A protein (p.Gly3618Ser). This variant is present in population databases (rs778158900, gnomAD 0.01%). This missense change has been observed in individual(s) with autosomal recessive retinitis pigmentosa and deafness (PMID: 20507924, 23967202). ClinVar contains an entry for this variant (Variation ID: 553008). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
