Description

This sequence change replaces tryptophan, which is neutral and slightly polar, with cysteine, which is neutral and slightly polar, at codon 272 of the TYR protein (p.Trp272Cys). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with oculocutaneous albinism (PMID: 10987646, 15606524). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 99581). 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%. For these reasons, this variant has been classified as Pathogenic.
