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.

This sequence change creates a premature translational stop signal (p.Glu2288*) in the USH2A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in USH2A are known to be pathogenic (PMID: 10729113, 10909849, 20507924, 25649381). This variant is present in population databases (rs398124619, gnomAD 0.002%). This premature translational stop signal has been observed in individuals with Usher syndrome type II (PMID: 19881469, 22135276, 23924366). ClinVar contains an entry for this variant (Variation ID: 96666). For these reasons, this variant has been classified as Pathogenic. -
