Conditions with this feature

MedGen UID:
Concept ID:
Congenital Abnormality
Piebaldism is a rare autosomal dominant trait characterized by the congenital absence of melanocytes in affected areas of the skin and hair. A white forelock of hair, often triangular in shape, may be the only manifestation, or both the hair and the underlying forehead may be involved. The eyebrows and eyelashes may be affected. Irregularly shaped white patches may be observed on the face, trunk, and extremities, usually in a symmetrical distribution. Typically, islands of hyperpigmentation are present within and at the border of depigmented areas (summary by Thomas et al., 2004).
Piebald trait-neurologic defects syndrome
MedGen UID:
Concept ID:
Disease or Syndrome
A rare genetic pigmentation anomaly of the skin syndrome with characteristics of ventral as well as dorsal leukoderma of the trunk and a congenital white forelock in association with cerebellar ataxia, impaired motor coordination, intellectual disability of variable severity and progressive, mild to profound, unilateral or bilateral sensorineural hearing loss. There have been no further descriptions in the literature since 1971.
