How to Check Your MAO-A Enzyme?Genes

There is no SNP?that perfectly correlates with 2-5R version. ?There are only snps that correlate with these versions somewhat. ?It depends on groups of snps and also on your gender.

You can check some SNPs from?23andme by looking for:

Rs909525?(MAOA Gene)?–?This is the best proxy for the number of repeats of the MAOA warrior gene.

If you have “TT” or just “T” (males), then you most probably have the less aggressive version. (R) ?T=Less Aggressive.

It was always “T” in people with the 4 or 5R non-Warrior version and always “C” in people with the 3R?Warrior version. But if you are “C”, it doesn’t mean you have the warrior gene and if you are “T”, it doesn’t mean you don’t. ?It just means it’s more likely. (R) ?C=More Aggressive.

On the other hand, men (but not females) with the T allele had higher rates of suicide compared to controls (70.5% vs 54%). (R)

The combination?rs909525(T) AND?rs6323(G) ANDrs3027399(G) indicate specifically that it is the 5R version. The 2R version and the 3.5R version weren’t mentioned. (R)

Rs2064070?– Males with:?rs909525 (C), rs6323 (G) and rs2064070 (A) had higher scores on the scale measuring expression of anger outwards. (R) ?Females with??TT allele reported higher ‘‘spontaneous aggression.”?(R)

Rs6323?(MAOA R297R?Gene)??–?The G or GG allele?indicates higher levels of the enzyme, while the T allele indicates lower levels (T is the ‘risk’ allele). (R) ??In females, the G allele was associated with?higher outward?anger (p = 0.002) and it seems like G allele also causes aggression in males. (R)G=More Aggression.

The?T allele was overrepresented in patients suffering from generalized anxiety disorder.?(R)T=Anxiety.

Females with TT?reported higher levels of ‘‘angry temperament’’. ?Female suicide attempters with TT reported higher ‘‘self-aggression’’. (R)

Rs3027399?(MAOA)?–?The combination?rs909525(A) AND?rs6323(G) AND?rs3027399(G) indicate specifically that it is the 5R version. The 2R version and the 3.5R version weren’t mentioned. (R)

Rs2235186 (MAOA Gene)?was correlated with anger control traits of healthy female college students in China. (R) ?I don’t know which allele was associated with more anger control.

Rs1799836?(MAOB) – Different gene, but why not include it. ?“TT” was associated with being angry?in both males and females. (R)
