Albinism is genetic disorder caused by gene mutations on the chromosomes that causes a lack of melanin pigment in the eyes, skin, and hair. Individuals with this condition may have problems with the skin or eyes. There are four types of albinism; Oculocutaneous albinism, X-linked ocular albinism, Hermansky-Pudlak syndrome,and Chediak-Higashi syndrome. Oculocutaneous albinism is caused by a mutation in chromosome 11, chromosome 15, chromosome 9, or chromosome 5. The mutations result in signs and symptoms related to vision, skin,hair and iris color. The cause of X-linked ocular albinism is a gene mutation on the x chromosome. Individuals with x-linked ocular albinism have the developmental and functional vision problems of albinism. But a person’s skin, hair and eye color are generally normal or slightly lighter. Hermansky-Pudlak syndrome is a rare albinism disorder caused by one of at least seven mutated genes. People with this disorder have the same symptoms as ocular albinism, but may also develop lung and/or bowel diseases. Chediak-Higashi syndrome is a rare form of albinism caused by a mutation on chromosome 1. Signs and symptoms are also similar to those of oculocutaneous albinism. The hair is usually brown or blond with a silvery sheen, and the skin is usually creamy white to grayish. Individuals with this syndrome have a white blood cell defect that cause infections.
