Women who carry genetic variants tied to autism have an elevated chance of experiencing pregnancy-related events linked to the condition in their children.

Regions of the brain’s fear center expand in autistic children and teenagers with anxiety, but not in their autistic or non-autistic peers without anxiety.

The catalog could help researchers understand the effects of autism-linked DNA variants that fall outside genes.

Some copy number variants may boost a person’s chances of having autism, but to a lesser extent than previously thought.

Among thousands of Danish adults diagnosed with autism after age 18, less than half were diagnosed with a psychiatric condition as children, a new study shows.

The first animal model of MYT1L syndrome suggests that fast-maturing neurons lead to the unusually small brains, social deficits and other traits seen in people with the condition.

Children born to mothers who take antipsychotic drugs during pregnancy are not more likely to have autism or attention deficit hyperactivity disorder, or to be born preterm or underweight.

Worms and zebrafish missing both copies of the gene CHD7 have disrupted cellular signaling, a dearth of inhibitory neurons and behavior changes — all of which are reversed by the stimulant drug ephedrine.

When autism researcher Clare Harrop tried to recruit survey participants over social media, she received hundreds of fraudulent responses. But there are ways researchers can protect themselves from similar experiences.

Welcome to the Null and Noteworthy newsletter, a roundup of papers that do the vital work of reproducing a previous result or reporting the absence of one.
