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: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 196 of the USH2A protein (p.Pro196Ser). This variant is present in population databases (rs756041909, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 498472). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt USH2A protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Pro196Ser variant in USH2A has not been previously reported in individuals with hearing loss or Usher syndrome, but was identified in 0.008% (11/128782) o f European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This varian t has been reported in ClinVar (Variation ID 498472). Computational prediction t ools and conservation analysis do not provide strong support for or against an i mpact to the protein. In summary, the clinical significance of this variant is u ncertain. ACMG/AMP Criteria applied: PM2_Supporting. -
