2 April 2012 - Susceptibility to post-traumatic stress disorder could be partially determined by gene variants, says a study.A US team looked at the DNA from 200 members of 12 families who survived the 1988 Armenian earthquake.
It found those who carried two gene variants which affect the production of serotonin - which affects mood and behaviour - were more likely to display symptoms of PTSD.
The research is published in Journal of Affective Disorders.
PTSD can arise after any kind of experience that causes trauma, whether that be in war, after a natural disaster or because of child abuse or sexual assault.
Symptoms can include flashbacks, feeling emotionally numb or hyper-alert to danger, and avoiding situations that act as reminders of the original trauma.
It is estimated that up to 3% of the general population is likely to be affected by PTSD at some point.
