Downs SM, van Dyck PC, Rinaldo P, et al. Other rare variants include nonsense, splicing, and small and large deletions. Trimethylaminuria is a presumably genetic defect in the enzymatic conversion of trimethylamine (odor of stale fish) to trimethylamine-N-oxide (non-odiferous). Even without mutations to FMO3, some people may experience trimethylaminuria from an intake of large doses of TMA or products that increase TMA production. If a persons body has a fishy smell, they may have trimethylaminuria. [Full Text] [ncbi.nlm.nih.gov]. Contact: Lab Client Services People can take the recommended dosage of 3040 mg between three and five times a day with meals. (2014). The excess TMA is then released through bodily fluids like sweat and urine. Genetic testing is also available, though usually not necessary to make a diagnosis. This changed gene cant give instructions for making the FMO3 enzyme. People may also undergo genetic testing, which can show whether there is a mutation in the FMO3 gene that causes trimethylaminuria. Trimethylaminuria causes the body to produce a fishy odor that is released in the sweat, urine, breath, and reproductive fluids. Choline bitrate is available from Douglas Laboratories, provided in 500 mg capsules. This compound is often associated with atherosclerosis and severe cardiovascular disease.

People assigned female at birth (AFAB) may have more severe symptoms just before and during their periods, after taking oral contraceptives and as they go through menopause. In people with primary trimethylaminuria (with mutations in FMO3) there will be too much TMA compared to TMAO in the urine. People with TMAU are unable to completely break down trimethylamine (TMA), a chemical found naturally in many foods, especially those containing the essential nutrient choline. A mutation in the FMO3 gene affects the FMO3 enzyme. Nervous system diseases are usually diagnosed and treated by neurologists. Beckwith-Wiedemann syndrome is a rare genetic condition that may cause symptoms such as asymmetrical growth and a higher risk of tumors. Is there routine newborn testing for trimethylaminuria? This enzyme converts trimethylamine to trimethylamine N-oxide, which has no smell. Genes are stretches of DNA. The urine test involves collecting samples of urine before and after patients are given a large dose of compounds that are converted to trimethylamine. The way trimethylaminuria is inherited is called 'autosomal recessive'.
