Genetics, nutrition, and external environmental factors all collectively contribute to increasing the probability an autoimmune skin disease occurring. [3] The severity of symptoms varies based on the specific disease present and how far it has progressed. Diagnosis often requires the onset of visible symptoms and for a biopsy to be performed ...
Type 2E is caused by an autosomal dominant mutation in the gene SOX10. [4] Rarely, a mutation in a gene other than those currently known may be responsible for a Waardenburg syndrome with features of type 2. This is usually initially classified as simply type 2 but may be given its own subtype once a gene or locus is identified and established. [7]

Some genetic conditions that result in a "leucistic" appearance include piebaldism, Waardenburg syndrome, vitiligo, Chédiak–Higashi syndrome, flavism, isabellinism, xanthochromism, axanthism, amelanism, and melanophilin mutations. Pale patches of skin, feathers, or fur (often referred to as "depigmentation") can also result from injury.
The condition is very common in mice, rabbits, dogs, sheep, deer, cattle and horses—where selective breeding has increased the incidence of the mutation—but occurs among chimpanzees and other primates only as rarely as among humans. Piebaldism is unrelated to conditions such as vitiligo or poliosis.
Genodermatosis is a hereditary skin disease with three inherited modes including single gene inheritance, multiple gene inheritance and chromosome inheritance. [1] There are many different types of genodermatosis; the prevalence of genodermatosis ranges from 1 per 6000 people to 1 per 500,000 people. [2]

Several genetic and acquired disorders can mimic poliosis, and they should be considered during diagnosis: Oculocutaneous albinism (OCA): A group of inherited disorders that affect melanin production, causing pale skin, hair, and eyes. [11] Griscelli syndrome: A rare genetic condition characterized by pigmentary dilution and immunodeficiency. [12]
