Summary
This gene is one of two neighboring gene family members that encode mitochondrial enzymes which catalyze the oxidative deamination of amines, such as dopamine, norepinephrine, and serotonin. Mutation of this gene results in Brunner syndrome. This gene has also been associated with a variety of other psychiatric disorders, including antisocial behavior. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Jul 2012]

Protein Information
 
Protein Name
Amine oxidase [flavin-containing] A, monoamine oxidase type A
 
Function
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOA preferentially oxidizes biogenic amines such as 5-hydroxytryptamine (5-HT), norepinephrine and epinephrine

3 PCOS patients and 3 non- PCOS patients 
LGCs from PCOS cells treated with Cb2 present more significant changes at the transcriptomiclevel than non-PCOS cells. To validate whether there were significant differences between Cb2-treated and -untreated samples, seven key genes were selected by GSEA analysis, The RT-qPCR results for all validated genes showed the same trend as found in the microarray experiment, confirming the microarray data. In addition, most of the changes were significant (P value <0.05).
