MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene plays a key role in the acute regulation of steroid hormone synthesis by enhancing the conversion of cholesterol into pregnenolone. This protein permits the cleavage of cholesterol into pregnenolone by mediating the transport of cholesterol from the outer mitochondrial membrane to the inner mitochondrial membrane. Mutations in this gene are a cause of congenital lipoid adrenal hyperplasia (CLAH), also called lipoid CAH. A pseudogene of this gene is located on chromosome 13. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice fail to thrive and die during the postnatal period due to adrenocortical insufficiency. Mice exhibit male pseudohermaprhoditism and show a progressive accumulation of lipids within steroidogenic cells of the adrenal glands and gonads. [provided by MGI curators]
