Dimethylaniline monooxygenase [N-oxide-forming] 4 is an enzyme that in humans is encoded by the FMO4 gene.Metabolic N-oxidation of the diet-derived amino-trimethylamine (TMA) is mediated by flavin-containing monooxygenase and is subject to an inherited FMO3 polymorphism in man resulting in a small subpopulation with reduced TMA N-oxidation capacity resulting in fish odor syndrome Trimethylaminuria.
