Piebaldism

Piebaldism is a rare autosomal dominant disorder of melanocyte development. Common characteristics include a congenital white forelock, scattered normal pigmented and hyperpigmented macules and a triangular shaped depigmented patch on the forehead.

Although piebaldism can be classed as partial albinism, the vision problems associated with albinism are not usually present as eye pigmentation is normal.

It may be associated with KIT or SNAI2.
