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]

Significance: Pathogenic
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 205 of the TYR protein (p.Pro205Thr). This variant is present in population databases (rs61754362, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of oculocutaneous albinism (PMID: 13680365; internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 99572). 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%. For these reasons, this variant has been classified as Pathogenic. -

The TYR c.613C>A variant is predicted to result in the amino acid substitution p.Pro205Thr. This variant has been reported in multiple individuals with oculocutaneous albinism (Camand et al. 2001. PubMed ID: 11295837; King et al. 2003. PubMed ID: 13680365; Hutton and Spritz. 2008. PubMed ID: 18463683). This variant is reported in 0.0054% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Given the evidence, we interpret this variant as pathogenic. -
