In people with primary trimethylaminuria (with mutations in FMO3) there will be too much TMA compared to TMAO in the urine. People may also undergo genetic testing, which can show whether there is a mutation in the FMO3 gene that causes trimethylaminuria. One of these copies comes from the mother in the egg and the other copy comes from the father in the sperm. Trimethylaminuria is a presumably genetic defect in the enzymatic conversion of trimethylamine (odor of stale fish) to trimethylamine-N-oxide (non-odiferous).
