Foul tempered women have their genes to blame
Women can blame their genes for their foul temper as University of Pittsburgh researchers have revealed that anger, hostility and pugnacity may be rooted in variations in the DNA of a serotonin receptor gene, which is responsible in the protein that picks up the brain messenger chemical serotonin.
Dr Indrani Halder, of the Cardiovascular Behavioural Medicine Programme at the University of Pittsburgh, will present the findings today at the American Psychosomatic Society's Annual Meeting in Budapest, Hungary, reports the Telegraph.
The study, the first to look at the relationship between variations in the serotonin receptor 2C gene and anger and hostility, focused on 550 unrelated European women.
Researchers found that those who had one or both of two alterations in the promoter region of the serotonin receptor - the part of the gene that turns it on - were more likely to score lower on tests for anger and aggression.
