“…The other CpGs on the significant list was cg26495008 and cg10913456, both in the FKBP Prolyl Isomerase 5 (FKBP5) gene, previously associated with childhood maltreatment and depression (Klinger-König et al, 2019;Mehta et al, 2013); and risk of PTSD (Binder et al, 2008;Pape et al, 2018). The role of other significant genes detected by ML include: Nuclear Factor Kappa B Subunit 1 (NFKB1), which has been associated with personality disorders (Gescher et al, 2018); Interleukin 4 (IL4), which has been associated with PTSD (Smith et al, 2011); Nuclear Receptor Subfamily 3 Group C Member 1 (NR3C1), previously associated with emotion dysregulation, psychopathology (Cicchetti & Handley, 2017), depression (Borçoi et al, 2020;Efstathopoulos et al, 2018), and risk of PTSD (Schechter et al, 2015;Vukojevic et al, 2014); and Nuclear Factor Of Activated T Cells 1 (NFATC1), which has been previously associated with PTSD and depression (Kuan et al, 2017). It is clear from the literature that GRRN genes play a crucial role in mediating the stress response, and many genes identified here by our ML analyses have been previously associated with traumatic stress and stress-related psychopathology.…”
