Choline is an essential nutrient found in meats, fish, nuts, beans, vegetables and eggs. Unfortunately at this time, enzyme replacement therapy with the enzyme FMO3, which when absent, is believed to cause the condition, is not an option in the management of trimethylaminuria. Problems with memory, senses, or mood may also occur. Due to the variability of symptoms people with trimethylaminuria experience, researchers think that different genetic mutations in FMO3 can influence the symptoms of the disease, affecting time of onset and how strong the odor is. If the FMO3 enzyme does not work properly, the body is unable to break down trimethylamine, and the chemical builds up in the body. [1] Therefore, it is recommended that you work with a medical or genetics professional to contact the laboratories for further information. People may also undergo genetic testing, which can show whether there is a mutation in the FMO3 gene that causes trimethylaminuria.
