An electronic catalog of human genes and genetic disorders, developed by the National Center for Biotechnology Information (NCBI). Monell Chemical Senses Center Healthcare providers call this primary trimethylaminuria. 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). The number and severity of symptoms experienced may differ among people with this disease. Clinical studies are medical research involving people as participants. They build public awareness of the disease and are a driving force behind research to improve patients' lives.

They also suspect that stress and diet play a role in triggering symptoms. Trimethylamine N-oxide does not smell. Since this condition usually requires two altered genes to cause symptoms, typically neither parent of an individual with trimethylaminuria has any symptoms. (2017).
