GENE INFORMATION
Gene name	OCA2 (HGNC Symbol)
Synonyms	BEY, BEY1, BEY2, D15S12, EYCL, EYCL2, EYCL3, P
Description	Oculocutaneous albinism II (HGNC Symbol)
Entrez gene summary	This gene encodes the human homolog of the mouse p (pink-eyed dilution) gene. The encoded protein is believed to be an integral membrane protein involved in small molecule transport, specifically tyrosine, which is a precursor to melanin synthesis. It is involved in mammalian pigmentation, where it may control skin color variation and act as a determinant of brown or blue eye color. Mutations in this gene result in type 2 oculocutaneous albinism. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
