[Epigenetics' implication in autism spectrum disorders: A review].
The etiology of autism spectrum disorders (ASD) is complex and multifactorial, and the roles of genetic and environmental factors in its emergence have been well documented. Current research tends to indicate that these two factors act in a synergistic manner. The processes underlying this interaction are still poorly known, but epigenetic modifications could be the mediator in the gene/environment interface. The epigenetic mechanisms have been implicated in susceptibility to stress and also in the pathogenesis of psychiatric disorders including depression and schizophrenia. Currently, several studies focus on the consideration of the etiological role of epigenetic regulation in ASD. ⋯ These recent discoveries in epigenetics are the beginnings of an etiopathogenic research revolution in neurodevelopmental disorders. The conceptualization of epigenetic processes is in its early stages and despite its limited means will help integrate disparate data factors previously involved in autism. It could also be the target for the development of new therapeutic modalities.
