This dictionary definitions page includes all the possible meanings, example usage and translations of the word albinism.
the congenital absence of pigmentation in the eyes and skin and hair
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.
Etymology: From albino (from albus/alba via and albo/alba, "white") + -ism.
Albinism is the congenital absence of melanin in an animal or plant resulting in white hair, feathers, scales and skin and pink or blue eyes. Individuals with the condition are referred to as albino. Varied use and interpretation of the terms mean that written reports of albinistic animals can be difficult to verify. Albinism can reduce the survivability of an animal; for example, it has been suggested that albino alligators have an average survival span of only 24 hours due to the lack of protection from UV radiation and their lack of camouflage to avoid predators. It is a common misconception that all albino animals have characteristic pink or red eyes (resulting from the lack of pigment in the iris allowing the blood vessels of the retina to be visible), however this is not the case for some forms of albinism. Familiar albino animals include in-bred strains of laboratory animals (rats, mice and rabbits), but populations of naturally occurring albino animals exist in the wild, e.g. Mexican cave tetra. Albinism is a well-recognized phenomenon in molluscs, both in the shell and in the soft parts. It has been claimed by some, e.g. that albinism can occur for a number of reasons aside from inheritance, including genetic mutations, diet, living conditions, age, disease, or injury. However, this is contrary to definitions where the condition is inherited. Oculocutaneous albinism (OCA) is a clearly defined set of seven types of genetic mutations which reduce or completely prevent the synthesis of eumelanin or pheomelanin, resulting in reduced pigmentation. Type I oculocutaneous albinism (OCA1a) is the form most commonly recognised as 'albino' as this results in a complete absence of melanin in the skin, hair/fur/feathers, and pink pupils, however this has led many to assume that all albinos are pure white with pink pupils, which is not the case.In plants, albinism is characterised by partial or complete loss of chlorophyll pigments and incomplete differentiation of chloroplast membranes. Albinism in plants interferes with photosynthesis, which can reduce survivability. Some plant variations may have white flowers or other parts. However, these plants are not totally devoid of chlorophyll. Terms associated with this phenomenon are "hypochromia" and "albiflora".
Albinism is a rare group of genetic disorders that cause the skin, hair, or eyes to have little or no color. It is characterized by a lack or reduced production of melanin, the pigment responsible for the color of the skin, hair, and eyes. Individuals with albinism often have vision problems and are at increased risk for skin cancer due to lack of skin pigmentation. It can occur in all racial and ethnic groups throughout the world.
the state or condition of being an albino: abinoism; leucopathy
Albinism is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. While an organism with complete absence of melanin is called an albino an organism with only a diminished amount of melanin is described as albinoid. Albinism is associated with a number of vision defects, such as photophobia, nystagmus and astigmatism. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak–Higashi syndrome, albinism 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.
U.S. National Library of Medicine
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.
that condition in which there is an absence of color or a whitening in a form usually colored.

Much more must be done to put an end to these heinous crimes and to protect this vulnerable segment of the population, attacks against people with albinism can never be justified – not by culture, tradition or religion.
The number one killer of people with albinism is skin cancer, not machete attacks and muti murders (ritual killings).
Police found the body in Biharamulo Forest Reserve yesterday with his arms and legs hacked off, when will Tanzanians stop believing in witch doctors who fuel the killings of persons with albinism for their body parts?
There's absolutely no political will among leaders to end these macabre killings ... what is so special with these (traditional) healers to the extent that our leaders ignore albino killings? albinism is not a disease. People must understand albinos are normal people like everyone else and the government has a role to play to ensure this education reaches many people since most of the killings involve members of the family.
