Any medical information published on this website is not intended as a substitute for informed medical advice and you should not take any action before consulting with a healthcare professional. Due to this, people with trimethylamine give off a strong fishlike odor. Some people may have trimethylaminuria because they have an inherited metabolic condition that blocks the enzyme from breaking down trimethylamine. This means that restricting your choline intake without having definitive biochemical TMAU testing and diagnosis could be detrimental to your health. We'll go over the science behind it and why it smells different. Depending on the type of mutation in the FMO3 gene, the amount of unmetabolized trimethylamine (and related odor) varies from person to person.

Work in conjunction with a health care provider or genetics professional to contact the laboratory and learn more about the clinical diagnostic testing the laboratory offers. WebTMAU is diagnosed using a biochemical laboratory test that measures the amount of trimethylamine in a patients urine after they drink juice containing added choline. Activated charcoal taken at a dose of 750mg twice daily for ten days. There is currently no cure for trimethylaminuria. However, it is possible for people with this condition to live normal, healthy lives. 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). Nervous system diseases are usually diagnosed and treated by neurologists. Having a hard time developing or maintaining relationships. WebIndividuals with trimethylaminuria should be followed by a genetics team, including a genetic counselor and geneticist, who can help determine that all appropriate specialists are being seen and recommend all appropriate management as well as provide information about testing and risk to family members. The genetic test involves looking for mutations (changes or mispellings) in the FMO3 gene that are known to cause with the disease. Copper chlorophyllin taken at a dose of 60mg three times a day after meals for three weeks. Who else in my family should I test for trimethylaminuria? Email: LabClientServices@childrenscolorado.org. If they have one faulty gene, they will be a carrier. Genes are stretches of DNA. The sq. An article about trimethylaminuria, written by Damaris Christensen, and published by ScienceNewsOnline, Volume 155, Number 20 (May 15, 1999), Effects of the dietary supplements, activated charcoal and copper chlorophyllin, on urinary excretion of trimethylamine in Japanese trimethylaminuria patients. Seattle (WA): University of Washington, Seattle; 1993-2016. Some people have TMAU due to defective genes passed down from their parents that affect their metabolism. 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. The first two steps involve eating a diet low in choline and trimethylamine (TMA) for three days.

The odor can smell like fish in some patients and like garbage in others. A carrier of this condition can be identified by the "TMA challenge" or a "TMA load" test. 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. These experts are ready to meet with you one-on-one and answer any questions you might have. They may offer online and in-person resources to help people live well with their disease. Trimethylaminuria is a rare disorder of metabolism characterized by a defect in the production of the enzyme flavin-containing monooxygenase 3 (FMO3) FMO3 is important for converting trimethylamine into trimethylamine oxide. This is the enzyme that converts trimethylamine to to trimethylamine N-oxide. 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. The developing embryo (the combined egg and sperm) can then be tested for the genetic changes in the FMO3 gene that cause trimethylaminuria in their family. The samples are analyzed to determine the amounts of trimethylamine (TMA) and trimethylamine N-oxide (TMAO) that are present to determine if the enzyme FMO3 can effectively convert odorous TMA to odorless TMAO when given large doses of compounds that are converted to TMA. Genetic counselors can help determine who in your family would benefit from testing by constructing a pedigree, or family tree.
