Nettet22. nov. 2024 · Background: Trimethylaminuria (TMAU) is a rare genetic disease characterized by the accumulation of trimethylamine (TMA) and its subsequent excretion trough main body fluids, determining the characteristic fish odour in affected patients. We realized an experimental study to investigate the role of several coding variants in the … NettetAkerman et al. (1997) and Dolphin et al. (1997) demonstrated that trimethylaminuria is caused by mutation in the FMO3 gene ().One individual of British extraction was shown to be homozygous for an E305X mutation (136132.0001) of the FMO3 gene; this person, in addition to trimethylaminuria, had tachycardia and severe hypertension after eating …

Nettet1. jan. 2013 · We hypothesize that the mild decrease in FMO3 activity in our patient is linked to relative developmental deficiency of FMO3 (Koukouritaki et al. 2002) and to genetic susceptibility caused by compound heterozygosity for a severe mutation (p.Tyr331X) on one allele and two polymorphisms (E308G; E158K) on the second … Nettet15. sep. 2013 · Trimethylaminuria (TMAu) or “fish odor syndrome” is a metabolic disorder characterized by the inability to convert malodorous dietarily-derived trimethylamine (TMA) to odorless TMA N-oxide by the flavin-containing monooxygenase 3 (FMO3). Affected individuals unable to complete this reaction exude a “fishy” body odor due to the …
NettetTrimethylaminuria (TMAU), also known as fish odor syndrome or fish malodor syndrome, is a rare metabolic disorder that causes a defect in the normal production of an enzyme named flavin-containing monooxygenase 3 (FMO3). When FMO3 is not working correctly or if not enough enzyme is produced, the body loses the ability to properly convert …
Nettet16. mar. 2024 · Trimethylaminuria is usually an inherited condition that occurs due to an affected flavin-containing monooxygenase 3 ( FMO3) gene.
