Albinism is a genetic disorder characterized by the complete or partial absence of pigment in the skin, hair, and eyes. People with albinism have a recessive gene mutation that results in a lack of melanin production. The most common type of albinism is Oculocutaneous Albinism (OCA). This type of albinism affects the eyes, skin, and hair. People with OCA type 1 have no melanin in their eyes and very little in their skin and hair. People with OCA type 2 have some melanin in their eyes, skin, and hair. OCA type 3 is the least common type of albinism and affects only the skin and hair.
Subtitle Genotype
The genotype of albinism is a recessive gene mutation. This means that in order for a person to have albinism, they must have two mutated copies of the gene that codes for melanin production. If a person has only one mutated copy of the gene, they will not have albinism, but they will be a carrier of the gene and can pass it on to their children.
