Cold Spring Harbor Laboratory (CSHL) researchers have flipped the script on autism spectrum disorder (ASD) genetics. Scientists long thought that siblings born with ASD share more of their mother’s genome than their father’s. But CSHL Associate Professor Ivan Iossifov and Professor Michael Wigler have now shown that, in many cases, it’s dad who might be playing a bigger genetic role. Autism spectrum disorders cover a range of neurological and developmental conditions. They can affect how a person communicates, socializes, learns, and behaves. ASD may also manifest as repetitive behaviors ...
