Genes affected

TYRP1 (HGNC:12450): (tyrosinase related protein 1) This gene encodes a melanosomal enzyme that belongs to the tyrosinase family and plays an important role in the melanin biosynthetic pathway. Defects in this gene are the cause of rufous oculocutaneous albinism and oculocutaneous albinism type III. [provided by RefSeq, Mar 2009]

LURAP1L-AS1 (HGNC:49761): (LURAP1L antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.508 is higher than 0.05.
