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.

Glu3088Lys in exon 47 of USH2A: This variant is not expected to have clinical si gnificance because it has been identified in 0.7% (47/7020) of European American chromosomes and 0.2% (7/3738) of African American chromosomes from a broad popu lation by the NHLBI Exome sequencing project (http://evs.gs.washington.edu/EVS/; (rs56056328). It addition, it occurrs at an equal frequency in cases and contro ls (McGee 2010; Dreyer 2008). -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: USH2A c.9262G>A (p.Glu3088Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0064 in 251272 control chromosomes in the gnomAD database, including 12 homozygotes. This frequency is not significantly higher than estimated for a pathogenic variant in USH2A causing Usher Syndrome (0.0064 vs 0.011), allowing no conclusion about variant significance. Although this variant has been reported in the literature, to our knowledge, no occurrence of c.9262G>A in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Six clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as benign/likely benign. Based on the evidence outlined above, the variant was classified as benign. -
