The Minor "C" allele is associated with:

  • More Aggressive behavior. The combination rs909525(T) 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).

The Major "T" allele is associated with:

  • Less Aggressive behavior. It was always "T" of people with the 4 or 5R non-Warrior version and always "C" in people with the 3RWarrior 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)
  • Males (but not females) with the T allele had higher rates of suicide compared to controls (70.5% vs 54%) (R).
