When FMO3 is not working correctly or if not enough enzyme is produced, the body loses the ability to properly convert trimethylamine (TMA) from precursor compounds in food digestion into trimethylamine oxide (TMAO), through a process called N-oxidation. Combining this bad breath and body odor can cause the person experiencing the condition to be very self-conscious. Treacy EP, Lambert DM.

The trimethylamine is then carried to the liver where it is converted to trimethylamine N-oxide, a metabolic product that has no odor. If an individual receives one normal gene and one gene for the disease, the person will be a carrier for the disease, but usually will not show symptoms. J. Hum.
