Any disease state or compromise anywhere in the gastrointestinal tract or in the organs of detoxification and elimination (liver,kidneys, skin, lungs) can be related to TMAU, especially in the liver which may already be struggling due to the genetic component of TMAU.

Trimethylaminuria or TMAU is a rare metabolic disorder that means the body cannot break down a compound called trimethylamine. There are two types of TMAU: Type 1 is identified as those born with the condition due to a faulty gene (called the FMO3 gene) inherited from a parent. Dietary supplements such as activated charcoal and copper chlorophyllin can bind trimethylamine in the gut and hence reduce the amount available for absorption. "It's like living with a death sentence - I wouldn't wish it on my worst enemy, it's that bad," she said. Cashman JR[19] found that 53% of TMAU and 59% of non-TMAU subjects suffered from regular halitosis, dental plaque on the back of the tongue, which produced on average "200-600 ppb of sulfurous/fecal smelling volatile sulfur compounds (i.e., VSC: hydrogen sulfide; methylmercaptan; dimethylsulfide) with each exhalation, creating a malodorous cloud in their vicinity. Ways that may help eliminate the fishy odor include avoiding foods containing trimethylamine and its precursors like: The only test for trimethylaminuria at this time is a urine test for elevated levels of trimethylamine. Why Do Some People Have Trimethylaminuria When Their Parents Don't? [5] The proportion of precursor converted to TMA is related to the amount of specific bacteria in the gut.[6]. Although lecithin, creatinine and betaine are technically precursors to TMA, pilot studies have shown no significant effect on the production of excess TMA/TMAO in urinary analysis at normal dietary levels of consumption. There's currently no cure, but there are things that can help. The syndrome can cause a range of other health problems, including intellectual disability, poor eyesight, seizures, as well as noncancerous tumors, and deep venous thrombosis, a condition. The major bacterial converters of choline, carnitine and lecithin are mostly neutral, pathogenic or opportunistic microbes. Mrs Thomas said the smell was with her every day but on some days or for part of a day the odour could be less intense. Genetic counselling may help you understand the risks of passing trimethylaminuria on to any children you have. [9], The condition seems to be more common in women than men, for unknown reasons. The bacteria in our gut play a vital role in helping us break down and digest our food. 2001;29:517-21. It's not a critical disorder. In: Adam MP, Ardinger HH, Pagon RA, et al., editors.

TMA is a diet-derived amine that originates from . Some clinicians believe that the disorder is under-diagnosed since many people with mild symptoms do not seek help. Trimethylaminuria (TMAU) also known as "fish odor syndrome" (OMIM #602079) is a rare inherited metabolic condition associated with decreased hepatic trimethylamine N-oxidation, which leads to an excess of the volatile trimethylamine (TMA) instead of substrate conversion to TMA N-oxide (TMAO).1-3TMA is a tertiary amine derived from the Additionally, when a food substance, supplement or medicine containing a precursor (choline or carnitine) is ingested, bacteria in the gut convert a portion of those precursors to TMA. TMAU (Trimethylaminuria): The Causes, Types and Triggers. Foods high in choline such as eggs, liver . TMA is a chemical found in fish, sharks and rays, molluscs, and crustaceans, and is the main odorant that is characteristic of degrading seafood. Rev. The address is P.O. With input from doctors, researchers, and the US Food & Drug Administration, NORD has created IAMRARE to facilitate patient-powered natural history studies to shape rare disease research and treatments. Quincy, MA 02169 Trimethylaminuria (TMAU) is an uncommon condition that causes an unpleasant, fishy smell. ed., Wiley Encyclopedia of Molecular Medicine. Fruits and Vegetables: 1 cup raw or cooked vegetable, such as carrots, celery, tomatoes, sweet potato, squash zucchini including skin, sauerkraut, radishes, cucumber, green and red peppers.

No physical symptoms are associated with trimethylaminuria. Pharmacogenetics. Trimethylamine (TMA) is a volatile, foul-smelling, diet-derived amine, primarily generated in the colon and metabolized in the liver to its odorless N-oxide (TMAO). Avoiding all seafood, including fish, shellfish, kelp, seaweed. 2000;10:439-51. Page last reviewed: 16 April 2021 In: NORD Guide to Rare Disorders. The specimen may still be viable within four hours if it is refrigerated between 2 and 8C. [10][11][12] Loss-of-function mutations, nonsense mutations, and missense mutations are three of the most common. When the normal metabolic process fails, trimethylamine accumulates in the body, and its odor is detected in the person's sweat, urine and breath.

In terms of reducing inflammation, relieving symptoms and reducing or slowing the progressiveness of a disorder, the Probiotic Pack is a great natural alternative for Trimethylaminuria. Trimethylamine is notable for its unpleasant smell. Trimethylaminuria is a disorder, which by definition is an extreme example of chemical individuality or variation of normal as described by Garrod in the Croonian lectures at the turn of the last century. In individuals with a hereditary defect in flavin-containing monooxygenase 3 (FMO3), bacterial TMA production is believed to contribute to the symptoms of trimethylaminuria (TMAU; fish-odor syndrome). In women, symptoms may worsen just before and during menstrual periods, after taking oral contraceptives, and around menopause. Ellie James, 44, has the rare condition known as Trimethylaminuria (TMAU), which prevents the body from breaking down materials found in certain foods. Any disease state or compromise anywhere in the gastrointestinal tract or in the organs of detoxification and elimination (liver,kidneys, skin, lungs) can be related to TMAU, especially in the liver which may already be struggling due to the genetic component of TMAU. When FMO3 is not working correctly or if not enough enzyme is produced, the body loses the ability to properly convert trimethylamine (TMA) from precursor compounds in food digestion into trimethylamine oxide (TMAO), through a process called N-oxidation. It is not the friendly strains of bacteria in the gut that break down and convert choline and other substances from the diet in to TMA. - The syndrome occurs when an unpleasant smelling chemical trimethylamine (TMA) can't be broken down by the liver into a different chemical that doesn't . Without this enzyme, foods containing carnitine, choline and/or trimethylamine N-oxide are processed to trimethylamine and no further, causing a strong fishy odor. Females are at higher risk for suffering from trimethylaminuria than males. The TMA is then absorbed and goes to the liver, routes (A or (B). Financial support is derived from advertisements or referral programs, where indicated. Several reports have concluded that symptoms can worsen at the time of puberty and there is also evidence that symptoms get worse just prior . This secondary form of the disorder is a result of an overload of trimethylamine. https://www.clinicaltrialregister.eu/. If you have secondary then they say it is bacteria in the gut that produces FMO3 and the liver isn't able to clear this toxin hence it comes out through the skin. lactis, BB-12, on defecation frequency in healthy subjects with low defecation frequency and abdominal discomfort: a randomised, double-blind, placebo-controlled, parallel-group trial , British Journal of Nutrition (Human and Clinical Nutrition).
