RCV003553974 | SCV004295754 | pathogenic | not provided | 2024-01-16 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 81 of the TYR protein (p.Pro81Ser). This variant is present in population databases (rs754654473, gnomAD 0.0009%). This missense change has been observed in individual(s) with oculocutaneous albinism (PMID: 13680365, 29345414, 30472657). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. 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 TYR protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects TYR function (PMID: 27537549). This variant disrupts the p.Pro81 amino acid residue in TYR. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1970634, 8434585, 10987646, 29345414). 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. |
