Albinism
Albinism is a rare inherited defect in melanin metabolism. Albinism can affect two things, the skin and eyes which is called oculocutaneous albinism or just the eyes which is ocular albinism. The word "albinism" refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. They have inherited genes that do not make the usual amounts of a pigment called melanin. One person in 17,000 in the U.S.A. has some type of albinism. Albinism affects people from all races. Most children with albinism are born to parents who have normal hair and eye color for their ethnic backgrounds. Often people do not recognize that they have albinism. (NOAH). Oculocutaneous albinism is from autosomal recessive inheritance; ocular albinism is from an X-linked recessive trait that causes hypopigmentation. In the United States both types of albinism are more common in blacks then in whites, Native Americans have a high incidence of the tyrosine-positive form (1 in 140 to 240). Infants wit
(WebMD) People in albinism cannot be out in the sun without wearing glasses, and clothing that covers up their whole body. Albinism is passed from parent to their kid through genes. If sun exposure produces a sunburn, then the skin must be protected to prevent burning and damage. People with albinism are at risk of isolation, because the condition and they are often misunderstood. Ty-Neg albinism or also called type 1A results from a genetic defect in an enzyme called tyrosinase. The mothers have subtle eye changes which an ophthalmogist could identigy, but mothers usually have normal vision. The description is hereditary deficiency pigmentation. It's hard for people with albinism to live a normal life when they cannot go out in the sun. In conclusion the facts on people with albinism are that one in 17,000 people has some type of albinism. Albinism people can live a regular lifespan but they must stay out of the sun, if they don't, they are in danger of dying at a younger age. For nearly all types of albinism both parent must carry an albinism gene to have a child with albinism. Albinism affects people from all races. This is now a well-documented condition. This type of inheritance is called autosomal recessive inheritance.
