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.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The His752His variant in USH2A: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue, is not located near a splice junction, and is commonly reported in cis with the pathogenic Cys759Phe variant (Rivolta 2002, Rivolta 2000, Aller 2004, Bernal 2005, Seyedahmadi 2004) . In addition, this variant has been identified in 0.2% (13/7020) of European Am erican chromosomes and 0.03% (1/3738) of African American chromosomes in a broad population by the NHLBI Exome sequencing project (http://evs.gs.washington.edu/ EVS/; dbSNP rs111033281). -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
