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.

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant, c.6795_6797del, is a complex sequence change that results in the deletion of 2 and insertion of 1 amino acid(s) in the USH2A protein (p.Glu2265_Tyr2266delinsAsp). This variant is present in population databases (rs727503723, gnomAD 0.002%). This variant has been observed in individual(s) with Usher syndrome (PMID: 22135276, 26667666, 27957503). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 166478). For these reasons, this variant has been classified as Pathogenic. -
