Trimethylaminuria, or TMAU, is a very rare condition that makes your sweat, breathe, saliva and pee smell like rotten fish or rotten eggs. 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. Therefore it's estimated that the majority of TMA would be filtered out within 48 hours if no additional TMA or precursor is ingested, regardless of liver function. There is the possibility that someone may suffer from both Trimethylaminuria and ORS-like paranoia, due to the potential lack of ability to smell the odour oneself and the worry that it generates.

Choline- and betaine-defined diets for use in clinical research and for the management of trimethylaminuria. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease. trimethylaminuria (TMAU) is inherited recessively as a defect in hepatic N-oxidation of dietary derived trimethylamine (TMA) results in excess excretion of TMA which gives affected individuals a body odour resembling rotten fish Primary TMAU sufferers generally have some residual FMO3 activity in the liver which processes TMA, however this happens relatively slowly. Testimonials are Individual Results. Using new case studies, Abie Lateef and Sylvie Marshall-Lucette examine the causes and consequences of 'fish odour syndrome', an under-researched and distressing condition that can have .

[5] When taken in large quantities (12g/day) betaine has been known to cause fish odor symptoms,[7] meaning that there is some conversion of betaine to TMA if supplements are taken regularly. Trimethylaminuria, also known as fish odour syndrome, is an autosomal recessive inherited disorder characterised by a body odour likened to rotten fish. Symptoms develop when the ability of the liver enzyme (flavin-containing monooxygenase 3) is insufficient to break down (metabolize) the excess trimethylamine. Mol. The parents themselves might only have 1 copy of the faulty gene. NORD and MedicAlert Foundation have teamed up on a new program to provide protection to rare disease patients in emergency situations. The condition is caused by a homozygous mutation in the FMO3 (flavin monooxygenase 3) gene coding for the enzyme that converts TMA ( trimethylamine) to trimethylamine N-oxide. Although FMO3 mutations account for most known cases of trimethylaminuria, some cases are caused by other factors. Relationship: The Role of Probiotics, Enzymes & Trimethylaminuria.
