Summaries for DHCR7 Gene

Entrez Gene Summary for DHCR7 Gene

  • This 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]

GeneCards Summary for DHCR7 Gene

DHCR7 (7-Dehydrocholesterol Reductase) is a Protein Coding gene. Diseases associated with DHCR7 include smith-lemli-opitz syndrome and sost-related sclerosing bone dysplasia. Among its related pathways are Metabolism and Terpenoid backbone biosynthesis. GO annotations related to this gene include oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor and 7-dehydrocholesterol reductase activity. An important paralog of this gene is TM7SF2.

UniProtKB/Swiss-Prot for DHCR7 Gene

  • Production of cholesterol by reduction of C7-C8 double bond of 7-dehydrocholesterol (7-DHC)

Tocris Summary for DHCR7 Gene

  • Delta7-Dehydrocholesterol reductase (DHCR) is a membrane-bound enzyme that catalyzes the final step of cholesterol biosynthesis (the reduction of the C7-8 double bond in 7-dehydrocholesterol to form cholesterol), using NADPH as a cofactor. DHCR is ubiquitously expressed.

  • Smith-Lemli-Opitz syndrome (SLOS) [MIM:270400]: An autosomal recessive frequent inborn disorder of sterol metabolism with characteristic congenital malformations and mental retardation. Children with SLOS have elevated serum 7-dehydrocholesterol (7-DHC) levels and low serum cholesterol levels. SLOS occurs in relatively high frequency: approximately 1 in 20,000 to 30,000 births in populations of northern and central European background. Historically, a clinical distinction often was made between classic (type I) SLOS and the more severely affected (type II) patients. There is, in reality, a clinical and biochemical continuum from mild to severe SLOS. {ECO:0000269 PubMed:10677299, ECO:0000269 PubMed:10995508, ECO:0000269 PubMed:11175299, ECO:0000269 PubMed:11427181, ECO:0000269 PubMed:12949967, ECO:0000269 PubMed:15954111, ECO:0000269 PubMed:9653161, ECO:0000269 PubMed:9683613}.
