Are you predisposed to PTSD?

The idea that your genes play a role in whether you develop PTSD is a popular focus of recent research. Scientists have discovered genes that help regulate fear reactions in mice. The lack of a fear-regulating brain chemical called gastrin-releasing peptide led to greater fear response among the rodents. In another study, mice without a protein necessary to form “fear memories” were less likely to freeze up and more willing to explore unknown spaces.
