Of all genes assigned to the module (n = 32), four were found differentially expressed after psychotherapeutic intervention in DGE analyses (IL1R2, ABCA1, KLF9 and LRRC4) and seven were previously reported as trauma associated (MME, TREML2, MMP9, IL1R2, ABCA1, NAMPTP1 and FKBP5, a major regulator of the glucocorticoid mediated stress response, and previously associated with PTSD (49)). The gene discussed is IL1R2; the disease is post-traumatic stress disorder.
