Record overview

MGPD IDMGP000826
Gene ID1717
SpeciesHomo sapiens (Human)
Gene Name7-dehydrocholesterol reductase
Gene Symbol DHCR7
SynonymsSLOS;
Alternate names7-dehydrocholesterol reductase; 7-DHC reductase; delta-7-dehydrocholesterol reductase; putative sterol reductase SR-2; sterol delta-7-reductase;
Chromosome11
Map Location11q13.4
EC Number1.3.1.21
SummaryThis gene encodes an enzyme that removes the C(7-8) double bond in the B ring of sterols and catalyzes the conversion of 7-dehydrocholesterol to cholesterol. This gene is ubiquitously expressed and its transmembrane protein localizes to the endoplasmic reticulum membrane and nuclear outer membrane. Mutations in this gene cause Smith-Lemli-Opitz syndrome (SLOS); a syndrome that is metabolically characterized by reduced serum cholesterol levels and elevated serum 7-dehydrocholesterol levels and phenotypically characterized by mental retardation, facial dysmorphism, syndactyly of second and third toes, and holoprosencephaly in severe cases to minimal physical abnormalities and near-normal intelligence in mild cases. Alternative splicing results in multiple transcript variants that encode the same protein.[provided by RefSeq, Aug 2009]
