摘要
Tyrosinase is a rate-limiting enzyme in the melanin biosynthetic pathway and a complete defect of the enzyme activity caused by homozygous mutations of the tyrosinase gene is well known to result in tyrosinase-negative oculocutaneous albinism (OCA1A) patients who never develop any melanin pigment in the skin, hair and eyes throughout life. In this paper, we report a novel missense substitution, R239W(CGG --> TGG) of the tyrosinase gene in a patient with tyrosinase-negative OCA.
