Genes affected

DHRS4L2 (HGNC:19731): (dehydrogenase/reductase 4 like 2) This gene encodes a member of the short chain dehydrogenase reductase family. The encoded protein may be an NADPH dependent retinol oxidoreductase. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Aug 2010]
