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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineFeb 17, 2011Variant classified as Uncertain Significance - Favor Benign. The Pro313His varia nt in USH2A has not been reported in the literature nor previously identified by our laboratory. Computational analyses (biochemical amino acid properties, homo logy, PolyPhen2, SIFT, AlignGVGD, MAPP) do not provide strong support for or aga inst pathogenicity. In summary, the clinical significance of this variant cannot be determined with certainty at this time. -
