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.

The p.Tyr534Cys variant in USH2A has not been previously reported in individuals with hearing loss but was reported in 1/11540 Latino chromosomes by the Exome A ggregation Consortium (http://exac.broadinstitute.org). Although this variant ha s been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses suggest that the p.Tyr534Cys variant may impact the protein, though this informa tion is not predictive enough to determine pathogenicity. In summary, the clinic al significance of the p.Tyr534Cys variant is uncertain. -
