Genes affected
RBP1 (HGNC:9919): (retinol binding protein 1) This gene encodes the carrier protein involved in the transport of retinol (vitamin A alcohol) from the liver storage site to peripheral tissue. Vitamin A is a fat-soluble vitamin necessary for growth, reproduction, differentiation of epithelial tissues, and vision. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]
COPB2-DT (HGNC:55579): (COPB2 divergent transcript)
