However, although variations in DNAm are frequently found in stress-related genes, unsupervised epigenome-wide association studies (EWAS) have shown limited reproducibility both between studies and in relating these changes to exposures.Consistent with stress theory, the expectation was that once the threat associated with an event was no longer present, the survivor would eventually recover from any lingering effects, and return to normal (pre-traumatic) functioning (American Psychiatric Association, 1968). Observations from survivors of traumatic historical events solidify that this disease is not only associated with personal experiences but can also be inherited from familial traumas. Although there are .Early and adult stress exposure is believed to have an association with epigenetic alteration of genes involved in mood regulation, for example, genes involved in the regulation of the HPA axis activity (NR3C1) or responsible for the serotonergic neurotransmission (SLC6A4).Epigenetics of traumatic stress: The association of NR3C1 methylation and posttraumatic stress disorder symptom changes in response to narrative exposure therapy Sarah Wilker 1,2,3 , Vanja Vukojevic 4,5, Anna Schneider2,3, Anett Pfeiffer2, Stefan Inerle6, Markus Pauly6,7, Thomas Elbert 2,8,, behavioral response to the tail suspension test)159, 162.
