In autism, a person’s brain may not form accurate predictions of imminent experiences, or even if it does, sensory input may override those predictions.

Children in families with a history of brain conditions may be at increased odds of being autistic.

Certain repeated stretches of DNA that are linked to the expansion of the primate brain may also enhance autism traits.

A study of more than 5 million people reveals the onset and prevalence of nine diagnoses that often accompany autism.

Autism may be just as common among children missing a segment of chromosome 16 as it is in those with an extra copy.

An analysis of DNA from more than 20,000 people with autism identifies 12 regions in the genome that harbor inherited risk factors for the condition.

A count of genetic variants may help predict a person’s risk of various conditions — but its clinical use prompts ethical questions.

This year’s list of top papers highlights new dimensions in our understanding of autism genetics and hints at novel treatments.

Autism and schizophrenia co-occur significantly more often than would be expected by chance, according to an analysis of nearly 2 million people.
