The autism spectrum disorder (ASD) includes a complex group of neural development disorders that arecharacterized by deficiencies in social interaction, communication, and motor skills of individuals. ASD has animpact on public health, so it would be very useful to have biomarkers that allow early identification of thedisorder. In this sense, microRNAs (miRNAs), which are regulators of a wide variety of cellular functionsand whose alterations in their expression have been observed in individuals with ASD, are beginning to beconsidered as potential targets for the development of diagnostic and therapeutic strategies for thesedisorders. This review focuses on some studies about the participation of miRNAs in ASD in animal models,as well as in humans, and makes an approach to their possible use as biomarkers.
