Variability in Drug Metabolizing Cytochrome P450 Activities Caused by Human Genetic Variations in NADPH Cytochrome P450 Oxidoreductase (POR)

Velazquez Maria Natalia Rojas , Parween Shaheena , Pandey Amit V

Background: A broad spectrum of human diseases, including abnormalities in steroidogenesis, are caused by mutations in the NADPH cytochrome P450 oxidoreductase (POR) (1-2). Cytochrome P450 proteins perform several reactions, including metabolism of steroids, drugs and other xenobiotics. Therefore, genetic variations in POR can impact many different metabolic pathways by changing the activities of cytochromes P450 (1). In 2004 the first human patients with defe...
