These changes can lead to transgenerational stress inheritance. [1] Epigenetic modifications play a role in the development and heritability of these disorders and related symptoms. For example, regulation of the hypothalamus-pituitary-adrenal axis by glucocorticoids plays a major role in stress response and is known to be epigenetically regulated.
