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 c.12598T>G (p.W4200G) alteration is located in exon 63 (coding exon 62) of the USH2A gene. This alteration results from a T to G substitution at nucleotide position 12598, causing the tryptophan (W) at amino acid position 4200 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Trp4200Gly in exon 63 of USH2A: This variant is not expected to have clinical si gnificance due to a lack of conservation across species, including mammals. Of n ote, at least 5 mammals (dolphin, killer whale, hedgehog, star-nosed mole, and c ape-golden mole) have a glycine (Gly) at this position despite high nearby amino acid conservation. In addition, it was identified in 0.6% (1/176) of African ch romosomes by the 1000 Genomes Project (http://www.1000genomes.org; dbSNP rs11411 6572). -
