Genes affected
LRMDA (HGNC:23405): (leucine rich melanocyte differentiation associated) This gene encodes a leucine-rich repeat protein. The encoded protein is thought to play a role in melanocyte differentiation. Mutations in this gene have been associated with autosomal recessive oculocutaneous albinism 7 (OCA7). Alternatively spliced transcript variants have been identified. [provided by RefSeq, Mar 2015]
LRMDA Gene-Disease associations (from GenCC):
  • oculocutaneous albinism type 7
