Trimethylamine is present in high levels in milk obtained from wheat-fed cows, Brassicas (brussel sprouts, broccoli, cabbage, and cauliflower), Lecithin and lecithin-containing fish oil supplements. The genetic test involves looking for mutations (changes or mispellings) in the FMO3 gene that are known to cause with the disease. Seattle (WA): University of Washington, Seattle; 1993-2016. 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). 11/2018 . Trimethylamine has a strong fishlike odor.

Clinical studies are medical research involving people as participants. If thats your situation, talk to your healthcare provider. Acidification of the urine to pH = 4 is preferred, although not required. Trimethylaminuria is a very rare condition. Improving newborn screening laboratory test ordering and result reporting using health information exchange. Carriers have one working copy of the FMO3 gene and one copy with a mutation.

This means a person must have two mutated FMO3 genes, one from each parent, to develop the condition. Because siblings of the affected individual have a 25% chance to be affected, they would benefit from testing to start diet changes early if they are affected. Mutations to FMO3 are generally inherited in a recessive pattern, meaning both parents are at least carriers of one copy of the mutated FMO3 gene. Healthcare providers diagnose TMAU by measuring the amount of trimethylamine in your urine (pee).
