NIH Rare Diseases:42 Piebaldism is a rare inherited condition characterized by a white forelock (a patch of white hair directly above the forehead). the name piebaldism is derived from the words “pie” (from magpie, which is a black and white bird) and “bald” (from the bald eagle, the us national bird that has a white feathered head). other features include a white patch on the central portion of the forehead; white eyebrow and eyelash hair; and white patches of skin on the face (particularly the chin), trunk and extremities (hands and feet are not usually affected). this condition is present at birth and usually remains unchanged throughout life. it is inherited in an autosomal dominant fashion and is caused by mutations in the kit gene. last updated: 4/4/2011

MalaCards: Piebaldism, also known as partial albinism, is related to neurofibromatosis and vitiligo, and has symptoms including anomalies of mouth, lip and philtrum, long philtrum and hearing loss/hypoacusia/deafness. An important gene associated with Piebaldism is KIT (v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog), and among its related pathways are Deregulation of Rab and Rab Effector Genes in Bladder Cancer and Regulation of KIT signaling. The compounds pkc 412 and monochloroacetic acid have been mentioned in the context of this disorder. Affiliated tissues include skin and eye, and related mouse phenotypes are endocrine/exocrine gland and pigmentation.

Genetics Home Reference:21 Piebaldism is a condition characterized by the absence of cells called melanocytes in certain areas of the skin and hair. Melanocytes produce the pigment melanin, which contributes to hair, eye, and skin color. The absence of melanocytes leads to patches of skin and hair that are lighter than normal. Approximately 90 percent of affected individuals have a white section of hair near their front hairline (a white forelock). The eyelashes, the eyebrows, and the skin under the forelock may also be unpigmented.
