Trimethylaminuria is a rare condition that causes a buildup of the chemical trimethylamine in the body. Rath S, et al. Trimethylaminuria is diagnosed by a urine test. Genetic testing is also available, though usually not necessary to make a diagnosis. The urine test can be done in two different ways.

Testing can be done by giving choline by mouth followed by urine collection a certain number of times over a 24 hour period. If a child is known to be at risk for trimethylaminuria and the specific mutations (misspellings) in the FMO3 gene (the gene associated with trimethylaminuria) are known, a child can be tested at birth. Talk to your healthcare provider about ways to manage your diet, exercise and stress so you have less noticeable TMAU symptoms. The sq. You should use the resources on this page to help you discuss TMAU with your PCP. It may be released in: sweat breath urine reproductive fluids The fish-like odor Their genetic counselors are specially trained and licensed healthcare providers. This compound is often associated with atherosclerosis and severe cardiovascular disease. There is no routine newborn testing for trimethylaminuria. Even without mutations to FMO3, some people may experience trimethylaminuria from an intake of large doses of TMA or products that increase TMA production. This service is provided by ThinkGenetic and is free. An electronic catalog of human genes and genetic disorders, developed by the National Center for Biotechnology Information (NCBI). DEPARTMENT OF PATHOL OGY AND LABORATORY M EDICINE . Healthcare providers may recommend you avoid the following foods: Eliminating these foods may reduce the amount of essential nutrients choline and folate, so ask your healthcare provider about ways to ensure you have enough choline and folate.

TMAU cant be cured. Healthcare providers call this primary trimethylaminuria. WebQuest Diagnostics and Cleveland HeartLab offer the TMAO (Trimethylamine N-Oxide) test (test code 94154) to assess the risk of MACE in individuals with moderate-to-very high risk of CVD. Identifying mutations is necessary if the patient wants to test a pregnancy for the disease. What does period blood smell like and why? Therefore, it is recommended that you work with a medical or genetics professional to contact the laboratories for further information.

Disease-causing variants, or differences, in the following gene(s) are known to cause this disease: FMO3. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. A urine test can show whether a person has high levels of trimethylamine in their urine. Biochemical Genetics Lab Immediately after each collection, each specimen should be acidified to pH = 4 (if possible) and should be frozen in a durable, tightly-sealed specimen tube. DNA is composed of 'letter', A, C, T, and G. With this testing, the FMO3 gene is sequenced; meaning each 'letter' of the gene is read to look for 'misspellings'. Trimethylamine (TMA) is a chemical compound that smells like rotting fish. 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.

Choline is an essential nutrient that humans need for neurodevelopment and many other bodily functions. This is a genetic rare disorder in which the body cannot break down the chemical trimethylamine.

A 2004 article by some of the same scientists on the 2008 USDA report includes a table of choline-rich foods. In 2008, a group of nutrition scientists published a US Department of Agriculture Report called the Database for the Choline Content of Common Foods, inspired by a 1999 conference on TMAU and sponsored by the National Institutes of Health. However, it may be possible to reduce the bad odor by taking different steps. Genetics Home Reference: Trimethylaminuria [ghr.nlm.nih.gov] Genetic testing can be performed after the affected family member has had genetic testing.

If youre pregnant or lactating, talk to your healthcare provider about other ways you can minimize TMAU symptoms. There is no cure. In people with primary trimethylaminuria (with mutations in FMO3) there will be too much TMA compared to TMAO in the urine. The excess trimethylamine builds up and is the source of the odor. Some people with TMAU have a strong odor all the time. Healthline Media does not provide medical advice, diagnosis, or treatment. TMAU is diagnosed using a biochemical laboratory test that measures the amount of trimethylamine in a patients urine after they drink juice containing added choline. Avoiding people because theyre embarrassed about their condition. Available treatments include dietary restrictions of choline and foods containing trimethylamine inhibitors. 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. Downs SM, van Dyck PC, Rinaldo P, et al. GARD is not currently aware of organizations specific to this condition. X It may be released in: The fish-like odor may vary in consistency or stay at a strong level. It is diagnosed based on the symptoms, clinical exam, urine analysis, and can be confirmed by genetic testing. Monell Chemical Senses Center MNT is the registered trade mark of Healthline Media. Taking riboflavin (vitamin B2) supplements to enhance any residual FMO3 enzyme activity. Include your email address to get a message when this question is answered. The language on this page about trimethylaminuria is technical but is considered to be a very comprehensive source of information. The following are some ways a person with trimethylaminuria can lower symptoms of odor: Avoiding foods containing trimethylamine and its precursors (choline, lecithin and trimethylamine N-oxide). Because siblings of the affected individual have a 25% chance to be affected, they would benefit from testing to start diet changes early if they are affected.
