Dopamine...\nThe infamous “serial killer gene� is the monoamine oxidase-A gene, also known as the MAO-A gene or the warrior gene. It codes for an enzyme that metabolizes neurotransmitters such as dopamine, norepinephrine, and serotonin. Dopamine and serotonin are the famed “happy hormones.� They are secreted when the reward centers of our brain are active. Norepinephrine or adrenaline is the reason behind our “fight or flight� response in the face of danger. The issue arises when the expression of the MAO-A gene is low. Without enough MAO-A enzyme to break down the neurotransmitters, the neurotransmitters accumulate. Studies conducted on a large Dutch family revealed that a few members of the family had a mutation that caused a complete absence of the MAO-A gene. They all seemed to display abnormally violent behavior. The ones that did not carry the mutation were relatively normal.\n
