FMO1 (flavin containing dimethylaniline monoxygenase 1)

Gene

• Entrez ID: 2326
• Gene name: Flavin containing dimethylaniline monoxygenase 1
• Gene symbol: FMO1
• Synonyms (NCBI Gene): -
• Chromosome: 1
• Chromosome location: 1q24.3
• Summary: Metabolic N-oxidation of the diet-derived amino-trimethylamine (TMA) is mediated by flavin-containing monooxygenase and is subject to an inherited FMO3 polymorphism in man resulting in a small subpopulation with reduced TMA N-oxidation capacity resulting
