During the research, Lizzy stumbled upon a very rare genetic disorder for which there is no known cure, Trimethylaminuria, TMAU for short. In this case, the person would be given a high dose of choline (one of the precursors of trimethylamine) and then have their urine tested for elevated levels of trimethylamine. For reasons that are unclear, many different mutations of the FMO3 gene exist. It is not due to a lack of hygiene. Today 2020; 259(9):1710-1717. https://doi.org/10.1016/j.drudis.2020.06.026.

This page is currently unavailable. TMA in the gut is absorbed through the intestinal lining and enters the bloodstream, where it is filtered by the liver. In primary trimethylaminuria (TMAU), an inherited deficiency in flavin-containing monooxygenase 3 leads to elevated systemic TMA levels For some metabolites the lab takes in samples from all over the UK. Phillips IR, Shephard EA. 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. Many cases have been identified with no malodor at all. Most TMAU2 sufferers produce too much TMA from intestinal bacteria due to an excess of the specific strains of bacteria that breakdown choline, carnitine and lecithin in to TMA.
