No. That review paper doesn’t discuss an actual mechanism, with good reason: the authors don’t have a mechanism. At the risk of sounding harsh, the underlying research has been throughly rubbished by the community [1, 2]. It uses a tiny sample size, tenuous correlation and, as mentioned, utterly fails at highlighting a plausible mechanism. It’s bunk: there’s absolutely no need to invoke the spectre of epigenetics to explain why children of traumatised parents may likewise be jumpy, just as there’s no need to invoke epigenetics to explain why children of English parents speak English. In fact, even the review you link to acknowledges as much:
> studies in humans have not yet demonstrated that the effects of trauma are heritable through non‐genomic (i.e., epigenetic) mechanisms
