Treatments of trimethylaminuria: where we are and where we might be heading. This treatment reduces the number of intestinal bacteria that break down choline and trimethylamine N-oxide into trimethylamine. Primary Trimethylaminuria. [citation needed], Mutations in the FMO3 gene, which is found on the long arm of chromosome 1, cause trimethylaminuria. GERD or reflux can result in dysbiosis. In primary trimethylaminuria (TMAU), an inherited deficiency in flavin-containing monooxygenase 3 leads to elevated systemic TMA levels The main symptom of TMAU is a foul-smelling body odor.

The malodorous aspect can have serious and destructive effects on schooling, personal life, career and relationships, resulting in social isolation, low self-esteem, depression, paranoid behavior, and suicide. The FMO3 gene makes an enzyme that breaks down nitrogen-containing compounds from the diet, including trimethylamine. Treacy EP. Analysis of her urine showed an elevated level of trimethylamine, and that a chemially pure free base sample of trimethylamine smelled similar to the patient's fishy odor. (2017). The risk for two carrier parents to both pass the altered gene and, therefore, have an affected child is 25% with each pregnancy.
