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.

Gly4692Ar in Exon 64 of USH2A: This variant is not expected to have clinical sig nificance because it has been identified in 0.6% (53/8600) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/; rs45549044). -

Variant summary: USH2A c.14074G>A (p.Gly4692Arg) results in a non-conservative amino acid change located in the Fibronectin Type III domain (IPR003961) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0047 in 250890 control chromosomes in the gnomAD database, including 6 homozygotes. Although reported in the literature, to our knowledge, no penetrant association of c.14074G>A in individuals affected with Usher Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. Eight 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. -
