COMT Gene The COMT gene is responsible for producing an enzyme called catechol-O-methyltransferase. This enzyme helps in the breakdown of catecholamines, thereby inactivating them. Catecholamines, termed as fight or flight hormones, include dopamine, epinephrine, and norepinephrine. They are produced in response to stress. They are responsible for increasing heart rate, blood pressure, breathing rate, muscle […]

MAO-A Gene: An introduction The MAO-A gene, popularly nicknamed the “warrior gene,” is responsible for the production of an enzyme monoamine oxidase A. (MAOA) It breaks down monoamine neurotransmitters (dopamine, epinephrine, and serotonin) through oxidation. Thus, mutations in the MAO-A gene can directly affect the levels of these neurotransmitters, which can potentially lead to various […]
