Objectives: The ability to identify persons at elevated risk for post-traumatic stress disorder (PTSD) soon after exposure to trauma, could aid clinical decision-making and treatment. In this study, we explored whether cytosine methylation of the 1 F promoter of the (glucocorticoid receptor [GR]) gene obtained immediately following a trauma could predict PTSD.
Methods: Our sample comprised 52 trauma survivors (28 women, 24 men), presenting to the Emergency Department (ED) within six hours of a traumatic event and followed for 13 months.
