Piebaldism is a rare autosomal dominant disorder of melanocyte development.James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders. ISBN 0-7216-2921-0. 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.
