RCV000826080 | SCV000967575 | uncertain significance | not specified | 2019-02-26 | criteria provided, single submitter | clinical testing | The p.Tyr4477Cys variant in USH2A has not been previously reported in individuals with hearing loss or Usher syndrome but has been identified in 0.006% (1/16230) African chromosomes by gnomAD (http://gnomad.broadinstitute.org). Computational prediction tools and conservation analysis suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of this variant is uncertain. ACMG/AMP Criteria applied: PM2, PP3. |

RCV001361727 | SCV001557714 | pathogenic | not provided | 2023-10-09 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 4477 of the USH2A protein (p.Tyr4477Cys). This variant is present in population databases (no rsID available, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of Usher syndrome (Invitae). ClinVar contains an entry for this variant (Variation ID: 667358). 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. For these reasons, this variant has been classified as Pathogenic. |
