People with TMAU are born with a defective version of the gene that codes for FMO3 and the resulting faulty FMO3 enzyme is unable to completely break down trimethylamine. GARD is not currently aware of organizations specific to this condition. More than 100 cases have been reported in medical literature, but some clinicians believe its underdiagnosed. Because of the biochemical nature of the excessive production of TMA, TMAU is linked to the intake of choline-rich foods, including eggs; broccoli; certain legumes such as soy, kidney beans; wheat germ; saltwater fish; and organ meats, including liver. TMAU symptoms often get worse during puberty, making children vulnerable to being bullied, shunned or ridiculed. 11/2018 . Testing can be done by giving choline by mouth followed by urine collection a certain number of times over a 24 hour period. We all have two copies of the gene that causes trimethylaminuria, FMO3.

Kabuki syndrome is a genetic syndrome that may be random or autosomal dominant.

Trimethylaminuria is a metabolic condition in which an individual is not able to convert trimethylamine into a compound called trimethylamine N-oxide. People can reduce the odor of trimethylamine by avoiding substances that increase production or levels of trimethylamine in the body, such as lecithin and choline. Trimethylaminuria, has been around for centuries, but has only gained scientific recognition and support in the past 30 years.
