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.

The p.Gly4401Val variant in USH2A has not been previously reported in individual s with hearing loss or in large population studies. Computational prediction too ls and conservation analysis suggest that the p.Gly4401Val variant may impact th e protein, though this information is not predictive enough to determine pathoge nicity. In summary, the clinical significance of the p.Gly4401Val variant is unc ertain. -
