Oculocutaneous albinism type 1A
... OCA1A is caused by mutations of the TYR gene that produce a inactive form of the tyrosinase enzyme. Parents of an affected child are considered to be obligate heterozygotes, each carrying a single copy of the disease-causing mutation in the TYR gene. The gene is located on chromosome 11, at 11q14 – ...
