The 2-repeat Allele of the MAOA Gene Confers an Increased Risk

for shooting and stabbing behaviors.
Abstract
There has been a great deal of research examining the link between a polymorphism in the promoter region of the MAOA gene and antisocial phenotypes. The results of these studies have consistently revealed that low activity MAOA alleles are related to antisocial behaviors for males who were maltreated as children.
Recently, though, some evidence has emerged indicating that a rare allele of the MAOA gene-that is, the 2-repeat allele-may have effects on violence that are independent of the environment. The current study builds on this research and examines the association between the 2-repeat allele and shooting and stabbing behaviors in a sample of males drawn from the National Longitudinal Study of Adolescent Health.
Analyses revealed that African-American males who carry the 2-repeat allele are significantly more likely than all other genotypes to engage in shooting and stabbing behaviors and to report having multiple shooting and stabbing victims. The limitations of the study are discussed and suggestions for future research are offered.

This is why we need more programs.

Regarding this 2-repeat allele, is it only found in African males, or more prevalently found in them? Is that what the article is saying?

Is this furthering the warrior gene concept? I haven’t started digging in. If so, it runs through many Mediterranean “white” bloodlines as well.
ETA: it is, just looked it up. Some theories out there it was spread into other populations during Roman times of conquest.

I think it’s old research. The people who called it the warrior gene got into political trouble because of it.
It was an unthinkable idea.

If you google the terms together, seems like many are still calling it that. And lol, to the last bit.
I’ll try to dig up something I watched by an American psych with Italian bloodlines who carries it himself.

Perhaps the “Shooty-Looty” gene is a better moniker.

It's significantly more prevalent in blacks than other races. I believe white's are 20% as likely to have it, Asians are less than 1% as likely to have it
