What is the difference between MAO A and MAO B?

Monoamine oxidase A (MAOA) generally metabolizes tyramine, norepinephrine (NE), serotonin (5-HT), and dopamine (DA) (and other less clinically relevant chemicals). In contrast, Monoamine oxidase B (MAOB) mainly metabolizes dopamine (DA) (and other less clinically relevant chemicals).

What does the MAOA gene do?

The MAOA gene provides instructions for making an enzyme called monoamine oxidase A. This enzyme is part of a family of enzymes that break down molecules called monoamines through a chemical reaction known as oxidation.

How common is the MAOA gene?
