A group of genetic disorders in which there is partial or total lack of the pigment melanin in the eyes, skin, and hair. See also: Albinism, oculocutaneous; Hermansky-Pudlak syndrome.

An hereditary disorder characterized by deficiency of the pigment melanin in the eyes, skin and hair. The lack of eye pigment causes photophobia (sensitivity to light), nystagmus, and decreased visual acuity. Oculocutaneous albinism is conventionally classified as to whether it is tyrosinase-negative or tyrosinase-positive. In the tyrosinase-negati [..]

A group of genetic conditions marked by little or none of the pigment melanin in the skin, hair, and/or eyes. People with albinism may have vision problems and white or yellow hair; reddish, violet, b [..]

lack of color in the skin, eyes and hair.

An abnormal lack of pigment.

  Hereditary absence of pigment in an organism. Albino animals have no colour in their skin, hair and eyes. The term is also used for absence of chlorophyll in plants.

The absence of all normal body pigmentation at birth, a condition that can occur in all races.

A group of inherited conditions that typically appear as a reduction or absence of melanin pigments in the skin, hair, and eyes.

General term for a number of inherited defects of amino acid Metabolism in which there is a deficiency or absence of pigment in the eyes, Skin, or Hair.

Albinism affecting the eye in which pigment of the Hair and Skin is normal or only slightly diluted. The classic type is X-linked (Nettleship-Falls), but an autosomal recessive form also exists. Ocula [..]

Lack of pigmentation of the skin, hair, and irises of the eyes.

A group of genetic conditions marked by little or none of the pigment melanin in the skin, hair, and/or eyes. People with albinism may have vision problems and white or yellow hair; reddish, violet, blue or brown eyes; and pale skin.

complete absence of green colour, resulting from genetic factors or chimaeral growth.

A skin defect that result in little or no color pigment in the skin, hair and eyes.

<dermatology> Condition in which no melanin (or other pigment) is present. (05 Feb 1998)

Albinism affecting the eye in which pigment of the hair and skin is normal or only slightly diluted. The classic type is x-linked (nettleship-falls), but an autosomal recessive form also exists. Ocular abnormalities may include reduced pigmentation of the iris, nystagmus, photophobia, strabismus, and decreased visual acuity. (12 Dec 1998)

Heterogeneous group of autosomal recessive disorders comprising at least four recognised types, all having in common varying degrees of hypopigmentation of the skin, hair, and eyes. The two most common are the tyrosinase-positive and tyrosinase-negative types. (12 Dec 1998)

A recessive hereditary trait which presents as white hair due to defective melanin production thought to be caused by a mutation within genes. Albinos have no melanin pigment and do not tan. Their skin is otherwise normal. Albinism affects people from all races.

A defect of melanin production that results in little or no color (pigment) in the skin, hair, and eyes.

An inherited disorder in which there is no pigmentation in skin, hair or eyes, due to the absence of melanin, the substance that gives skin its colour. Defective melanin production is thought to be ca [..]

Congenital lack of melanin pigmentation in the skin, eyes, and hair or feathers (or more rarely only in the eyes); the condition of being albino.

A genetic condition characterised by a lack of melanin production and subsequent partial or complete absence of pigment in the skin, hair and eyes.
