Do Angry Women Have Genetics to Blame?

Why are some women angrier than others? It may all be in the genes, says a new study by University of Pittsburgh researchers.

Prior studies have shown increased serotonin production to be associated with aggression and anger in humans and animals. In this study of 550 women, researchers found that those had one or two variations on the gene controlling serotonin reception scored lower on tests for hostility and anger, while women without this variation scored higher.

Researchers note that being able to identify variations a predisposition for feelings of anger may serve as a marker for physical health conditions.

"Aggression and hostility are predictors of hypertension, glucose metabolism and heart diseases," said researcher Indrani Halder, Ph.D. "The genetic marker we found for hostility also may be useful for predicting a person's predisposition to such diseases."
