<unk>  is a congenital condition characterized in<unk>  by the partial or complete absence of pigment in the skin, hair and eyes.<unk>  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. In rare cases such as Chédiak–Higashi syndrome,<unk>  may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection.<unk>  results from inheritance of recessive gene alleles and is known to affect all vertebrates, including<unk> . It is due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. Unlike<unk> , other animals have multiple pigments and for these,<unk>  is considered to be a hereditary condition characterised by the absence of melanin in particular, in the eyes, skin, hair, scales, feathers or cuticle. While an organism with complete absence of melanin is called an albino, an organism with only a diminished amount of melanin is described as leucistic or albinoid. The term is from the Latin albus, "white".
