Genes affected
TYR (HGNC:12442): (tyrosinase) The enzyme encoded by this gene catalyzes the first 2 steps, and at least 1 subsequent step, in the conversion of tyrosine to melanin. The enzyme has both tyrosine hydroxylase and dopa oxidase catalytic activities, and requires copper for function. Mutations in this gene result in oculocutaneous albinism, and nonpathologic polymorphisms result in skin pigmentation variation. The human genome contains a pseudogene similar to the 3' half of this gene. [provided by RefSeq, Oct 2008]

This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 47 of the TYR protein (p.Gly47Asp). This variant is present in population databases (rs61753180, gnomAD 0.1%). This missense change has been observed in individual(s) with oculocutaneous albinism (PMID: 1676041, 8128955, 8434585, 16417222, 19626598, 23242301, 23882993, 28976636). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It is commonly reported in individuals of Puerto Rican or Moroccan Jewish ancestry (PMID: 8128955, 8434585, 16417222, 23882993). ClinVar contains an entry for this variant (Variation ID: 3794). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt TYR protein function with a positive predictive value of 95%. This variant disrupts the p.Gly47 amino acid residue in TYR. Other variant(s) that disrupt this residue have been observed in individuals with TYR-related conditions (PMID: 8434585, 26167114, 29345414), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -

The TYR c.140G>A variant is predicted to result in the amino acid substitution p.Gly47Asp. This variant has been reported many times as causative for autosomal recessive oculocutaneous albinism (see for examples Oetting et al. 1993. PubMed ID: 8434585; Gershoni-Baruch et al. 1994. PubMed ID: 8128955; Camand et al. 2001. PubMed ID: 11295837; Marti et al. 2017. PubMed ID: 28976636). This variant is reported in 0.11% of alleles in individuals of Latino descent in gnomAD. This variant has been classified as pathogenic by multiple independent submitters to the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/3794). Given all the evidence, we interpret this variant as pathogenic. -
