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 c.652-9T>G variant in USH2A has not been previously reported in individuals with hearing loss or Usher syndrome, or in large population studies. This varian t is located in the 5' splice region. Computational tools do not suggest an impa ct to splicing. However, this information is not predictive enough to rule out p athogenicity. In summary, the clinical significance of the c.652-9T>G variant is uncertain. -
