Other Names for this Disease
- Fish malodor syndrome
- Fish odor syndrome
- Stale fish syndrome
metabolic disorder that occurs when the body is unable to break down certain nitrogen-containing compounds such as trimethylamine. Trimethylamine, which has a fishy odor, is produced in the intestines when certain types of food (i.e. eggs, liver, legumes, fish and some vegetables) are digested. As trimethylamine begins to accumulate in the body, it is released in the sweat, urine, reproductive fluids, and breath. This leads to the characteristic odor of trimethylaminuria. This condition is caused by changes (mutations) in the FMO3 gene and is inherited in an autosomal recessive manner. Although there is no cure, trimethylaminuria can often be managed by reducing the amount of trimethylamine in the body. For example, affected people can modify their diet to avoid foods with high levels of trimethylamine.Trimethylaminuria is a
