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.

p.Arg2175His in exon 34 of USH2A: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, 5 mammals (prairie vole, Chinese hamster, naked mole rat, guinea pig, and chinchilla) have a histidine (His) at this position despite high nearby amino a cid conservation. This variant has been identified in 0.26% (22/8612) of East As ian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinst itute.org; dbSNP rs140845899). -
