Albinism (from Latin albus, "white"; see extended etymology) is a form of hypopigmentary congenital disorder, ...

 


Albinism is a genetic condition resulting in a lack of pigmentation in the eyes, skin and hair. It is an inherited condition arising from the combination of recessive genes passed from both parents of an individual.

albinism
the absence of normal pigments in the hair, skin, and eyes of animals, or the absence of chlorophyll in plants that normally possess it

albinism Genetic condition caused by the body's inability to manufacture pigments; an autosomal recessive trait.
aldosterone A hormone secreted by the adrenal glands that controls the reabsorption of sodium in the renal tubule of the nephron.

Albinism, the lack of pigmentation in skin, hair, and eyes, is also a Mendelian human trait. Homozygous recessive (aa) individuals make no pigments, and so have face, hair, and eyes that are white to yellow.

X-Linked Ocular Albinism. Ballabio and Dick Lewis (BCM) have found an altered gene in the Xp22.3 region in patients with X-linked ocular albinism of the Nettleship-Falls type (OA1), a severe disorder affecting the eyes and the skin.

One of the genes that's needed to make color is tyrosinase, and if you don't have tyrosinase, if it's mutated, it results in a condition call albinism. So the fur or the skin's completely white because you can't make the pigment.
