Entrez Gene Summary for SLC45A2 Gene

  • This gene encodes a transporter protein that mediates melanin synthesis. The protein is expressed in a high percentage of melanoma cell lines. Mutations in this gene are a cause of oculocutaneous albinism type 4, and polymorphisms in this gene are associated with variations in skin and hair color. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

Variants for SLC45A2 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for SLC45A2 Gene

Genetic variants in SLC45A2 define the skin/hair/eye pigmentation variation locus 5 (SHEP5) [MIM:227240]. Hair, eye and 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 and hair color is found among individuals of European ancestry, with most other human populations fixed for brown eyes and black hair.
