Albinism - Symptoms and causes - Mayo Clinic
2023年12月13日 · Several genes give instructions for making one of several proteins involved in producing melanin. Melanin is made by cells called melanocytes that are found in your skin, hair and eyes. Albinism is caused by a change in one of these genes. Different types of albinism can occur, based mainly on which gene change caused the disorder.
Albinism: Types, Symptoms & Causes - Cleveland Clinic
Albinism is a rare genetic condition caused by mutations, or changes, of certain genes that affect the amount of melanin your body produces. Melanin controls the pigmentation (color) of your skin, eyes and hair. People with albinism have extremely pale skin, eyes and hair. They’re at an increased risk of vision, skin and social issues.
Albinism in humans - Wikipedia
Albinism is a congenital condition characterized in humans by the partial or complete absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers.

Molecular basis of albinism: mutations and polymorphisms of ...
Albinism, caused by a deficiency of melanin pigment in the skin, hair, and eye (oculocutaneous albinism [OCA]), or primarily in the eye (ocular albinism [OA]), results from mutations in genes involved in the biosynthesis of melanin pigment.

Comprehensive Review of the Genetics of Albinism
2018年11月1日 · It is important to understand albinism, since it is a disorder associated with visual impairment, predisposition to malignant melanomas, and social stigma. The main objective of this article is to review the genetics and biologic mechanisms of the non-syndromic albinism subtypes and to describe associated clinical manifestations.
