Warrior Gene Test

The “warrior” gene DNA test detects a genetic variant of the MAOA gene. The MAOA gene gives instructions to make the enzyme monoamine oxidase A, which is responsible for breaking down neurotransmitters (chemical messengers in the brain).

The “warrior” gene variant is also known as the MAOA-L gene. Individuals who inherit the “warrior” gene make lower levels of the enzyme monoamine oxidase A leading to an accumulation of neurotransmitters in the brain. This accumulation may explain some of the behavioral characteristics linked to the “warrior” gene including aggressive behavior and impulsive decision making.

What is measured?

The “warrior” gene DNA test detects the presence of repeats near the MAOA gene. Five different lengths of repeats are included in this test: 2R, 3R, 3.5R, 4R and 5R.

• Individuals with 2R, 3R and/or 5R have the “warrior” gene
• Individuals with 3.5R and/or 4R make normal levels of MAOA protein

The “warrior” gene is more likely to affect men because it is found on the X chromosome. Men only inherit one copy of the X chromosome. As such the presence of the variant will lead to lower enzyme levels. In contrast, women inherit two copies of the MAOA gene and will need to inherit two copies of the “warrior” gene to be impacted by it.
