The protein encoded by this gene catalyzes the reduction of 3-ketodihydrosphingosine to dihydrosphingosine. The putative active site residues of the encoded protein are found on the cytosolic side of the endoplasmic reticulum membrane. A chromosomal rearrangement involving this gene is a cause of follicular lymphoma, also known as type II chronic lymphatic leukemia. The mutation of a conserved residue in the bovine ortholog causes spinal muscular atrophy. [provided by RefSeq, Jul 2008]
KDSR (3-Ketodihydrosphingosine Reductase) is a Protein Coding gene. Diseases associated with KDSR include Erythrokeratodermia Variabilis Et Progressiva 4 and Distal Chromosome 18Q Deletion Syndrome. Among its related pathways are Sphingolipid metabolism and Metabolism. Gene Ontology (GO) annotations related to this gene include oxidoreductase activity and 3-dehydrosphinganine reductase activity. An important paralog of this gene is RDH13.
