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.

Leu2015Phe in exon 30 of USH2A: This variant has been identified in 0.02% (2/860 0) of European American chromosomes from a broad population by the NHLBI Exome S equencing Project (http://evs.gs.washington.edu/EVS/). It is not expected to hav e clinical significance due to a lack of conservation across species, including mammals. Of note, guinea pig, dolphin, cow and tenrec have a phenylalanine (Phe ) at this position. Therefore, this variant is likely benign. -
