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 replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 5060 of the USH2A protein (p.Ser5060Pro). This variant is present in population databases (rs752377040, gnomAD 0.06%). This missense change has been observed in individual(s) with retinitis pigmentosa and/or Usher syndrome (PMID: 25649381, 29625443, 29899460, 31904091; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 552090). 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 with a negative predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -
