Decoding distortions in the brain’s largest nerve tract could lay bare basic problems with long-range neural connections in autism.

A surprising number of genes associated with autism also have links to cancer. Does that mean cancer drugs can treat autism?

Researchers are beginning to understand how mutations in a cancer-linked pathway called WNT contribute to autism.

A comprehensive catalog of the genes that show ties to both autism and cancer highlights the role of cell growth in both conditions.

The brain enlargement seen in many children with autism may reveal hints about the condition’s causes.

The same autism-linked mutation can lead to dramatically different behaviors in rats and mice.

Two studies prioritize autism risk genes for further research and illuminate how different types of mutations may work together.

Children with autism who have low vasopressin levels struggle to understand the thoughts of others.

Mutations in the gene DYRK1A underlie a type of autism marked by an unusually small head. The new work expands the breadth of symptoms included under the autism umbrella.

Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.
