The flavin-containing monooxygenases (FMOs) are a family of related enzymes that are poised to metabolize many of the drugs and xenobiotics that we are exposed to (by oral, inhalation or dermal exposure). Depending on the type of chemical, FMO metabolism can produce metabolites that are more or less toxic than the parent compound. Because a polymorphism exists for FMO2 in 26% of African-Americans and 5-10% of Hispanic-Americans, we hypothesize that there is potential for a distinct therapeutic response or unintended risk as a consequence of substrate exposure. Research studies to determine the relevance of FMO2 variants are underway. Lung cell lines differentially expressing FMO2 provide a platform for in vitro tests, while the Fmo2 knockout mouse under construction will allow in vivo testing of FMO2 variants. Studies of FMO structure and function are also ongoing.
