Anger can be pinned on genes

Do you often get angry? Well, then, blame your genes, says a new study.

German researchers say that a gene called DARPP-32 may help explain why some people fly into a rage at the slightest provocation, while others remain calm.

The researchers, from the University of Bonn, asked over 800 people to fill in a questionnaire designed to study how they handle anger. The team also administered a DNA test to determine which of three versions of the DARPP-32 gene people were carrying.

The gene affects levels of dopamine, a brain chemical linked to anger and aggression. Researchers found that those who had the “TT” or “TC” versions of the gene portrayed significantly more anger than those with the “CC” version.

The researchers also found that those who display more anger have less grey matter in the amygdala, a part of the brain that helps keep our emotions balanced.
