Anger would be governed by genes

Bonn, Germany - A new study, anger management is genetic. The isolation of the gene called DARPP-32 can explain why some people put in a black rage at the slightest provocation, while others remain calm.

The DARPP-32 gene is responsible for the level of dopamine, a hormone released by the brain linked to anger and aggression. The existence of multiple versions of the gene explains how anger is expressed more or less depending on the individual.

For this study, more than 800 people filled out a questionnaire to investigate how they managed their anger. The German researchers have also carried out DNA tests to find out what version of the DARPP-32 gene each person covered. Those with the TT or TC gene showed significantly more anger than those with the CC. The study by the University of Bonn also shows that those who are angry have less gray matter in the tonsillar complex, part of the brain that helps balance the emotions.

Martin Reuter, one of the researchers, continues: "In other words, they are not able to control their feelings as well as those with the mutation-free version.

The TT and TC versions are more common in western populations. Researchers explain that the demonstrations of anger can help people move forward in life. "High levels of anger are obviously socially undesirable but some degree of behavior helps to become dominant in the social hierarchy" they state.

In the report published in the journal Behavioral Brain Research, scientists say that genetics accounts for only about half of our predisposition to anger and that DARPP-32 is one of many genes involved. Other studies have shown this year that show of anger rather than suppress his emotions is the key to professional success and personal.
