OMIA group 209

Coat colour, dominant white

The chain reaches the human disease piebaldism, which Mondo defines as: “Piebaldism is a rare congenital pigmentation skin disorder characterized by the presence of hypopigmented and depigmented skin areas (leukoderma) on various parts of the body, preferentially on the forehead, chest, abdomen, upper arms, and lower extremities, that are associated with a white forelock (poliosis), and in some cases with hypopigmented and depigmented eyebrows and eyelashes.”

The chain

From the animal disease to the drugs. The page shows what each step found and where the chain stopped. It does not say whether the animal is a model of a human disease.

Human diseases

Two routes lead from an OMIA group to a Mondo human disease: OMIA's own Mondo link, and the group's OMIM numbers through Mondo's cross-references.

OMIA's own Mondo link: OMIA links the group to no Mondo disease.
OMIA's OMIM numbers: found a disease.

Mondo disease	Name	Found by
MONDO:0008244	piebaldism Piebaldism is a rare congenital pigmentation skin disorder characterized by the presence of hypopigmented and depigmented skin areas (leukoderma) on various parts of the body, preferentially on the forehead, chest, abdomen, upper arms, and lower extremities, that are associated with a white forelock (poliosis), and in some cases with hypopigmented and depigmented eyebrows and eyelashes.
