Genes affected

FMO4 (HGNC:3772): (flavin containing dimethylaniline monoxygenase 4) Metabolic N-oxidation of diet-derived amino-trimethylamine (TMA) is mediated by flavin-containing monooxygenase and is subject to an inherited FMO3 polymorphism in man. This results in a small subpopulation with reduced TMA N-oxidation capacity and causes fish odor syndrome (Trimethylaminuria). Three forms of the enzyme are encoded by genes clustered in the 1q23-q25 region. Flavin-containing monooxygenases are NADPH-dependent flavoenzymes that catalyzes the oxidation of soft nucleophilic heteroatom centers in drugs, pesticides, and xenobiotics.

Nov 17, 2022

The c.614G>A (p.R205Q) alteration is located in exon 6 (coding exon 4) of the FMO4 gene. This alteration results from a G to A substitution at nucleotide position 614, causing the arginine (R) at amino acid position 205 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
