Common Name7,8-Didehydrodesmosterol
Description7-Dehydrodesmosterol is a sterol intermediate in the biosynthesis of steroids. 7-Dehydrodesmosterol is a substrate of the enzyme 24-dehydrocholesterol reductase (EC:1.3.1.72), an important enzyme in the biosynthesis of Cholesterol. Cholesterol is synthesized from either Lathosterol, 7-Dehydrocholesterol, Desmosterol or Cholestenol by the enzyme 3beta-hydroxysterol delta7 reductase (EC 1.3.1.21, Dhcr7). The Smith-Lemli-Opitz syndrome (SLOS, OMIM 270400 ) is caused by a genetic defect in cholesterol biosynthesis; mutations in the enzyme 3beta-hydroxysterol delta7 reductase lead to a failure of cholesterol synthesis, with an accumulation of precursor sterols, such as 7-Dehydrodesmosterol. SLOS results in craniofacial, limb as well as major organ defects, including the brain. In individuals with this syndrome, mental retardation, as well as other CNS dysfunction, is almost 100% prevalent. (PMID: 15862627 , 17197219 ).
