FKBP5 and post-traumatic stress disorder: We found a main effect of PTSD diagnosis on low-frequency power (slow-4 and slow-5 bands) in the parietal lobules and inferior frontal gyrus, and a main effect of FKBP5 diplotype on low-frequency power (slow-4 band) in ACC and middle-frequency power (slow-3 band) in the motor/sensory areas irrespective of PTSD diagnosis.
