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]

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Dec 12, 2023	This sequence change creates a premature translational stop signal (p.Arg402*) in the TYR gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TYR are known to be pathogenic (PMID: 23504663). This variant is present in population databases (rs62645917, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with clinical features of oculocutaneous albinism (PMID: 29345414). ClinVar contains an entry for this variant (Variation ID: 99542). For these reasons, this variant has been classified as Pathogenic. -
