Additional support for a role of Nr3c1 in risk for PTSD comes from a pair of studies demonstrating that individuals with the Nr3c1 polymorphism Bcl1 have been shown to have enhanced emotional memory recall (Ackermann et al., 2012), have lower levels of basal plasma cortisol levels, and recall more traumatic memories from time spent in intensive-care units following cardiac surgery (Hauer et al., 2011). This evidence concerns the gene CCND1 and post-traumatic stress disorder.
