They usually won't have symptoms, although some may have mild or temporary ones. People with trimethylaminuria end up with a build up of trimethylamine, which is then released through their sweat, urine, reproductive fluids, and breath. Ensuring that patients and caregivers are armed with the tools they need to live their best lives while managing their rare condition is a vital part of NORDs mission. Trimethylaminuria and deficiency of favin-containing monooxygenase type 3 (FMO3). J. Hum. [citation needed], Mutations in the FMO3 gene, which is found on the long arm of chromosome 1, cause trimethylaminuria. The prominent enzyme responsible for TMA N-oxygenation is coded by the FMO3 gene. When the normal metabolic process fails, trimethylamine accumulates in the body, and its odor is detected in the . Your resultsmay vary. Humans have several FMO genes, but only mutations in FMO3 cause trimethylaminuria. This secondary form of the disorder is a result of an overload of trimethylamine. Feel free to pm me, I'd love to know your story. 510., doi:10.4161/gmic.26749. Drug Metab. After a choline challenge load test (intentionally ingesting a TMA precursor) only 10% expressed a smell at a social distance, suggesting that those that produced odour had a more severe form of FMO3 impairment. Inherited trimethylaminuria (TMAU; OMIM #602079) is a well-described rare autosomal recessive genetic disorder associated with decreased hepatic trimethylamine N-oxidation, which leads to an excess of the volatile trimethylamine (TMA) instead of substrate conversion to trimethylamine N-oxide (TMAO). Several reports have concluded that symptoms can worsen at the time of puberty and there is also evidence that symptoms get worse just prior . The chance for a child to receive normal genes from both parents and be genetically normal for that particular trait is 25%. If we dont have a program for you now, please continue to check back with us. Ways that may help eliminate the fishy odor include avoiding foods containing trimethylamine and its precursors like: The only test for trimethylaminuria at this time is a urine test for elevated levels of trimethylamine. Getting tested is an important first step as a simple urine test will give you the answer; a blood test is available to provide genetic analysis. TMAU has thus been referred to historically as fish odor syndrome. Choline and lecithin are present in certain food supplements and health foods.

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 behavior, and suicide. This by-product is usually odorless. Parents who are close relatives (consanguineous) have a higher chance than unrelated parents of both carrying the same abnormal gene, which increases the risk of having children with a recessive genetic disorder. Excess trimethylamine is the cause of the fishy odor or rotten fish odor. 2002:1297-99. Trimethylaminuria. Cite This Page (APA): Disabled World.

When food is consumed that contains TMA and/or TMAO (predominately seafood; saltwater fish, shellfish, seaweed and kelp), TMAO is converted by bacteria in the lower gastrointestinal tract (gut) into TMA. Due to the fact that gut bacteria are involved in the conversion of dietary compounds to TMA, probiotics could play a role in the management of symptoms of Trimethylaminuria (TMAU). The risk of having a child who is a carrier like the parents is 50% with each pregnancy. Suite 310 A fish-like body odor could result from excess consumption of TMA precurors choline, carnitine and betaine (unobtainable via regular dietary intake, it requires high levels of supplement intake).
