SummarySkin color is highly individual and the variations are controlled by numerous genes. The different skin colors result from the size and number of melanosomes and do not mirror the amount of melanocytes. Disorders of pigmentation can result from migration abnormalities of melanocytes from the neural crest to the skin during embryogenesis.

Nail pigmentation is defined by the presence of melanin in the nail plate. It most frequently has the appearance of a longitudinal pigmented band, called longitudinal mel-anonychia (LM). LM is an important aspect of ungual pathology because it can be the first sign of nail apparatus melanoma.

Genetic disorders of pigmentation
Clinics in Dermatology, 2005More than 127 loci are actually known to affect pigmentation in mouse when they are mutated. From embryogenesis to transfer of melanin to the keratinocytes or melanocytes survival, any defect is able to alter the pigmentation process. Many gene mutations are now described, but the function of their product protein and their implication in melanogenesis

Genetic Disorders of Pigmentation
1994Disorders of pigmentation were among the first genetic disorders recognized in humans. The distinctive phenotypes of oculocutaneous albinism (OCA) and piebaldism were known to the ancient Greeks and Romans, and the typical clinical features, modes of inheritance, and genetic heterogeneity of these disorders are apparent even in classical descriptions ...
