Leucism (/ˈluːsɪzəm, -kɪz-/) is a term used to describe a wide variety of conditions which result in the partial loss of pigmentation in an animal—which causes white, pale, or patchy coloration of the skin, hair, feathers, scales or cuticles, but not the eyes. It is occasionally spelled leukism. Some genetic conditions that result in a “leucistic” appearance include piebaldism,Waardenburg syndrome, vitiligo, Chédiak–Higashi syndrome, and Melanophilin mutations. Pale patches of skin, feathers, or fur (often referred to as “depigmentation”) can also result from injury. As the term “leucism” is used to refer to conditions with a very wide range of unrelated causes it can not be considered to be a single, specific condition.
