Does everyone have the MAOA gene?

Humans have various forms of the gene, resulting in different levels of enzymatic activity. People with the low-activity form (MAOA-L) produce less of the enzyme, while the high-activity form (MAOA-H) produces more of the enzyme. … Only about a third of people in Western populations have the low-activity form of MAOA.
