Unfortunately at this time, enzyme replacement therapy with the enzyme FMO3, which when absent, is believed to cause the condition, is not an option in the management of trimethylaminuria. DNA is composed of four 'letters', A, C, T, and G. With this testing, the FMO3 gene is sequenced, meaning that each 'letter' of the gene is read to look for 'misspellings' (mutations). Carriers may have no signs of trimethylaminuria or mild symptoms, or temporary fish odor episodes. If the FMO3 enzyme does not work properly, the body is unable to break down trimethylamine, and the chemical builds up in the body.
