Invitae | RCV003554896 | SCV004292399 | pathogenic | not provided | 2024-01-03 | criteria provided, single submitter | clinical testing | This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 2309 of the USH2A protein (p.Cys2309Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with retinitis pigmentosa and/or Usher syndrome (PMID: 24265693, 36011334). 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 expected to disrupt USH2A protein function with a positive predictive value of 95%. This variant disrupts the p.Cys2309 amino acid residue in USH2A. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23591405, 26927203; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. |
