pigmentation
Deposition of pigment in tissue. Normal pigmentation of the skin is from melanocytes.
Pathology:
disorders of pigmentation include:
1) hyperpigmentation
2) hypopigmentation
Genetics:
- hair, eye & skin pigmentation are among the most visible examples of human phenotypic variation, with a broad normal range that is subject to substantial geographic stratification
- in the case of skin, individuals tend to have lighter pigmentation with increasing distance from the equator
- by contrast, the majority of variation in human eye & hair color is found among individuals of European ancestry, with most other human populations fixed for brown eyes & black hair
- genetic variations in ASIP are associated with variation in skin/hair/eye pigmentation type 9
