Epigenetic modifications, such as DNA methylation, can occur in response to environmental influences to alter the functional expression of genes in an enduring and potentially, intergenerationally transmissible manner. As such, they may explain inter-individual variation, as well as the long-lasting effects of trauma exposure. While there are currently no findings that suggest epigenetic modifications that are specific to PTSD or PTSD risk, many recent observations are compatible with epigenetic explanations. These include recent findings of stress-related gene expression, in utero contributions to infant biology, the association of PTSD risk with maternal PTSD, and the relevance of childhood adversity to the development of PTSD. The relevance of epigenetic mechanisms to formulations of PTSD for the DSM-V is described.
