MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Mice homozygous for disruptions in this gene die within one day of birth due to respiratory and suckling problems. They exhibit abnormal cholesterol homeostasis with reduced tissue cholesterol levels and total sterol levels, enlarged bladders and sometimes cleft palate. [provided by MGI curators]
