Mono-Amine Oxidase-A (MAOA) Gene

Also known as the “warrior gene”, this gene specifically produces the enzyme MAOA, which decomposes monoamine neurotransmitters (dopamine, serotonin, noradrenaline). Individuals with low levels of MAOA are more likely to react aggressively in a highly provocative situation.
