| Invitae | RCV001039355 | SCV001202885 | likely pathogenic | not provided | 2023-05-08 | criteria provided, single submitter | clinical testing | 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. ClinVar contains an entry for this variant (Variation ID: 837914). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with proline, which is neutral and non-polar, at codon 1608 of the USH2A protein (p.His1608Pro). This variant disrupts the p.His1608 amino acid residue in USH2A. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 23591405, 32675063; Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. |
