FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a flavin adenine dinucleotide (FAD)-dependent oxidoreductase which catalyzes the reduction of the delta-24 double bond of sterol intermediates during cholesterol biosynthesis. The protein contains a leader sequence that directs it to the endoplasmic reticulum membrane. Missense mutations in this gene have been associated with desmosterolosis. Also, reduced expression of the gene occurs in the temporal cortex of Alzheimer disease patients and overexpression has been observed in adrenal gland cancer cells. [provided by RefSeq, Jul 2008]
PHENOTYPE: In spite of having almost no plasma or tissue cholesterol, homozygous mutant mice are largely viable and display a mild growth phenotype. Inactivation did impair prenatal viability as well as infertility. [provided by MGI curators]
