oculocutaneous albinism
More than 80 mutations in the OCA2 gene have been identified in people withoculocutaneous albinism type 2. People with this form of albinism often have lightyellow, blond, or light brown hair; creamy white skin; light-colored eyes; and problems
with vision. The most common OCA2 mutation is a large deletion in the gene, whichis found in many affected individuals of sub-Saharan African heritage. Other OCA2gene mutations, including changes in single DNA building blocks (base pairs) andsmall deletions, are more common in other populations. Mutations in the OCA2 genedisrupt the normal production of melanin, which reduces coloring of the hair, skin, andeyes and affects vision.
