Taking low doses of antibiotics to reduce the amount of bacteria like trimethylamine in the gut, Taking activated charcoal or other supplements to decrease the concentration of free trimethylamine in the urine. Trimethylamine has been described as smelling like rotten or decaying fish. Nonsense and missense mutations cause the most severe phenotypes. TMAU has thus been referred to historically as fish odor syndrome. No physical symptoms are associated with trimethylaminuria. Your resultsmay vary. Changing lives of those with rare disease. There's currently no cure for trimethylaminuria, but some things might help with the smell. Trimethylamine is normally formed by bacterial action in the intestine on choline (found in foods such as soy, liver, kidneys, wheat germ, brewers yeast, and egg yolk), or on trimethylamine N-oxide (found in salt water fish). Lenherr N, Berndt A, Ritz N, Rudin C. Aerococcus urinae: a possible reason for malodorous urine in otherwise healthy children. Trimethylaminuria is a metabolic disorder that occurs when the body is unable to break down certain nitrogen-containing compounds such as trimethylamine. Trimethylaminuria is a metabolic condition in which an individual is not able to convert trimethylamine into a compound called trimethylamine N-oxide. Trimethylamine is also released in the person's sweat, reproductive fluids, and breath, and can give off a fishy odor when the concentration of trimethylamine is high enough to be detected. Some severe cases may require the administration of a gut-sterilizing antibiotic such as metronidazole. Testing includes organic acids, amino acids, acylcarnitine profiling and intermediary metabolites as well as the more specialist assays including sterols, trimethylamine, bile salts and quantitation of a range of compounds by gas chromatography mass spectrometry (GS/MS). Primary trimethylaminuria is caused by genetic mutations that affect the FMO3 function of the liver. 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). Telephone: 212-300-4168. Therefore, converting TMA directly in the gut using Archaebiotics belonging to the seventh methanogenic order, naturally-occurring in the gut: this would increase the efficiency of TMA conversion. Some clinicians believe that the disorder is under-diagnosed since many people with mild symptoms do not seek help. 'Mechanisms of Action of Probiotics and the Gastrointestinal Microbiota on Gut Motility and Constipation'. "It's not nice waking up in the morning with this condition.". Drug substrates may also impair metabolism in TMAU individuals. By alleviating the inflammation and clearing away this problem tissue it relieves the symptoms and allows the healing system to rapidly repair the problem. Symptoms matching TMAU can also occur when there is no genetic cause, yet excessive TMA excreted - this has been described as secondary trimethylaminuria (TMAU2). The ultimate goal of IAMRARE is to unite patients and research communities in the improvement of care and drug development. 1-3 TMA is a tertiary amine derived from the enterobacterial metabolism of precursors such as .

Foods high in choline such as eggs, liver . Inherited trimethylaminuria (TMAU; OMIM #602079) is a well-described rare autosomal recessive genetic disorder associated with decreased hepatic trimethylamine N-oxidation, which leads to an excess of the volatile trimethylamine (TMA) instead of substrate conversion to trimethylamine N-oxide (TMAO). Trimethylaminuria symptoms can be present from birth, but they may not start until later in life, often around puberty. J. Hum.
