MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This mitochondrial protein oxidizes cholesterol intermediates as part of the bile synthesis pathway. Since the conversion of cholesterol to bile acids is the major route for removing cholesterol from the body, this protein is important for overall cholesterol homeostasis. Mutations in this gene cause cerebrotendinous xanthomatosis, a rare autosomal recessive lipid storage disease. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null allele show hepato- and adrenomegaly, reduced bile acid synthesis, increased cholesterol 7alpha-hydroxylase activity and 7alpha-hydroxycholesterol levels, slightly higher 25-hydroxyvitamin D levels, and altered hepatic fatty acid, triacylglycerol, and adrenal cholesterol homeostasis. [provided by MGI curators]
