What is Albinism?

The enzyme produced by the TYR gene, called tyrosinase, is required for the synthesis of melanin pigment. A mutation in the TYR gene causes the most common form of albinism. People with albinism have either a partial or complete lack of pigment, or coloring, in their eyes, skin or hair.
