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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 116 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: -1.9514 (below the threshold of 3.09). Trascript score misZ: -0.85521 (below the threshold of 3.09). GenCC associations: The gene is linked to Waardenburg syndrome type 2, oculocutaneous albinism type 1A, oculocutaneous albinism type 1, oculocutaneous albinism type 1B, minimal pigment oculocutaneous albinism type 1, temperature-sensitive oculocutaneous albinism type 1.

BP4

Computational evidence support a benign effect (MetaRNN=0.10681164).
