The malodorous aspect can have serious and destructive effects on schooling, personal life, career and relationships, resulting in social isolation, low self-esteem, depression, paranoid behaviour, and suicide. Rev. Primary TMAU sufferers generally have some residual FMO3 activity in the liver which processes TMA, however this happens relatively slowly. Mol. INTERNET The parents of an individual with an autosomal recessive disorder are both carriers of one copy of the altered gene. Trimethylaminuria ( TMAU ), also known as fish odor syndrome or fish malodor syndrome, [1] is a rare metabolic disorder that causes a defect in the normal production of an enzyme named flavin-containing monooxygenase 3 ( FMO3 ). Trimethylaminuria is characterized by a fishy odour resembling that of rotten or decaying fish that results from excess excretion of trimethylamine. The prominent enzyme responsible for TMA N-oxygenation is the FMO3 gene. Although FMO3 mutations account for most known cases of trimethylaminuria, some cases are caused by other factors. Cite This Page (APA): Disabled World.

[4] Moderate amounts of precursor are absorbed in the small intestine before reaching the gut, however if precursor rich food saturates the transport capacity of the intestine, excess precursor ends up in the gut. In individuals with a hereditary defect in flavin-containing monooxygenase 3 (FMO3), bacterial TMA production is believed to contribute to the symptoms of trimethylaminuria (TMAU; fish-odor syndrome). The 2010 novel Boxer, Beetle by Ned Beauman features a character with trimethylaminuria.

Many people who suffer from trimethylaminuria, known colloquially as "fish malodor syndrome," also suffer from depression as a result of disruptions trimethylaminuria can cause to social life, relationships, or career. Dealing with trimethylamuinuria can be emotionally painful and isolating, but therapy and appropriate medical treatment can prove really helpful in alleviating some of its symptoms and repercussions.

On this Wikipedia the language links are at the top of the page across from the article title. The metabolic and clinical manifestations of TMAU are generally regarded as benign, as there is no associated organ dysfunction. In the case of mutations that do not completely abolish FMO3 activity, supplements of riboflavin might help maximize residual enzyme activity.
