The fish-odor smell is the obvious symptom; otherwise affected individuals appear normal and healthy. (For more information on this disorder, choose carnitine as your search words in the Rare Disease Database). There are more than 40 known mutations associated with TMAU. Findings found that the use of fecal/sewage as a description, and the use of multiple descriptors of the smell, and 'incorrect' locations of smell origin effectively differentiated ORS from TMAU. Trimethylaminuria. In this case, there is not enough of the enzyme to get rid of the excess trimethylamine. Currently, there is no cure and treatment options are limited for TMAU.

The Synbiotics (Probiotic & Prebiotics) contained in the Probiotic Pack helps to balance the immune system, promote nutrient absorption and healthy microbiome. The prominent enzyme responsible for TMA N-oxygenation is coded by the FMO3 gene. The risk is the same for males and females. After a choline challenge load test (intentionally ingesting a TMA precursor) only 10% expressed a smell at a social distance, suggesting that those that produced odour had a more severe form of FMO3 impairment. 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 The trimethylamine gets released in the person's sweat, urine, reproductive fluids, and breath, giving off a strong fishy or body odor.

A secondary form of trimethylaminuria may result from the side effects of treatment with large doses of the amino-acid derivative L-carnitine (levocarnitine) or choline. A variant of TMAU (secondary trimethylaminuria or TMAU2) exists where there is no genetic cause, yet excessive TMA is secreted, possibly due to intestinal dysbiosis, altered metabolism, or hormonal causes.

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). (2017). For known disabilities including `orphan' or rare disorders, there are often specific treatments available for the individuals affected. It's also called "fish odour syndrome".
