Abstract

Oculocutaneous albinism is an autosomal recessive genetic disorder. Several types of oculocutaneous albinism are caused by mutation in related genes. Oculocutaneous albinism 1 is associated with the tyrosinase gene. The human tyrosinase gene ( TYR) encodes tyrosinase, a key enzyme in melanin biosynthesis. As exon 1 of the gene shows an MboI-RFLP within codon 192 in Caucasians, we studied allele frequencies of MboI 192 polymorphism in 200 chromosomes from 100 unrelated normal Korean individuals. As a result, only one allele system, the presence of the MboI 192 site, was detected in the Korean.
