Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000041734 SCV000065430 uncertain significance not specified 2012-05-29 criteria provided, single submitter clinical testing The Cys4341Phe variant in USH2A has not been reported in the literature nor prev iously identified by our laboratory. Computational analyses (biochemical amino a cid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the C ys4341Phe variant may impact the protein, though this information is not predict ive enough to determine pathogenicity. In summary, the clinical significance of this variant cannot be determined with certainty.
Labcorp Genetics (formerly Invitae), Labcorp RCV003574707 SCV004329969 pathogenic not provided 2023-11-25 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with phenylalanine, which is neutral and non-polar, at codon 4341 of the USH2A protein (p.Cys4341Phe). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Usher syndrome (PMID: 25425308). ClinVar contains an entry for this variant (Variation ID: 48411). 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%. For these reasons, this variant has been classified as Pathogenic.
