Preliminary evidence suggests that changes in DNA methylation, a widely studied epigenetic
mechanism, contribute to the etiology of Autism Spectrum Disorder (ASD). However, data is
primarily derived from post-mortem brain samples or peripheral tissue from adults. Deep-phenotyped longitudinal infant cohorts are essential to understand how epigenetic modifications
relate to early developmental trajectories and emergence of ASD symptoms. We present a proof of-principle study designed to evaluate the potential of prospective epigenetic studies of infant
siblings of children with ASD.
