title: P450 oxidoreductase deficiency: a new disorder of steroidogenesis with multiple clinical manifestations.
abstract: Combined partial deficiency of 17alpha-hydroxylase and 21-hydroxylase is well-described, but patients' genes for these enzymes lack mutations. Recent work has identified mutations in the gene for P450 oxidoreductase (POR) in such patients. POR-deficient individuals have a broad range of disorders, from infants with congenital malformations to women with the polycysic ovary syndrome. POR transfers electrons to all microsomal P450 enzymes: its deficiency affects steroidogenesis, drug metabolism and other processes.
