FMO5

The information on this page was automatically extracted from online scientific databases.

What is the official name of the FMO5 gene?

The official name of this gene is “flavin containing monooxygenase 5.”

FMO5 is the gene's official symbol. The FMO5 gene is also known by other names, listed below.

What is the normal function of the FMO5 gene?

From NCBI Gene (http://www.ncbi.nlm.nih.gov/gene/2330):

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 in fish odor syndrome Trimethylaminuria. Three forms of the enzyme, FMO1 found in fetal liver, FMO2 found in adult liver, and FMO3 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2009]

From UniProt (http://www.uniprot.org/uniprot/P49326):

In contrast with other forms of FMO it does not seem to be a drug-metabolizing enzyme.

How are changes in the FMO5 gene related to health conditions?

Genetics Home Reference provides information about 1q21.1 microdeletion, which is associated with changes in the FMO5 gene.
