A recent discovery of a molecular connection between autism and myotonic dystrophy, a type of neuromuscular disease, may provide a breakthrough on how clinicians approach autism spectrum disorder. The new study by an interdisciplinary team of biomedical scientists, published on April 21 in Nature Neuroscience, used myotonic dystrophy as a tool or model to learn more about autism – effectively using one disorder to better understand the other.

Autism may be caused by a little-known genetic condition, experts say. They've found children with myotonic dystrophy type 1 (DM1) are also 14 times more likely to develop autistic spectrum disorder.

Scientists from The Hospital for Sick Children (SickKids) and the University of Las Vegas, Nevada (UNLV) have uncovered a genetic link between autism spectrum disorder (ASD) and a rare genetic condition called myotonic dystrophy type 1 (DM1).
