Trimethylaminuria is a rare disorder of metabolism characterized by a defect in the production of the enzyme flavin-containing monooxygenase 3 (FMO3) FMO3 is important for converting trimethylamine into trimethylamine oxide. Genetic testing is also available, though usually not necessary to make a diagnosis. This gene carries instructions on making the FMO3 enzyme. The majority of variants are missense. If sequencing the FMO3 gene does not uncover mutations, the gene can be analyzed for large deletions or duplications of 'letters' of the gene. Trimethylaminuria causes the body to produce a fishy odor that is released in the sweat, urine, breath, and reproductive fluids.
