Over the past year, HNRNPU, a gene well known for its link to epilepsy, has emerged as a new autism candidate.

A new method enables researchers to assess the biological impact of thousands of subtle mutations.

Mutations in certain genes contribute specifically to autism, and others only to developmental delay.

Genetic variants that affect mitochondria, the organelles that power cells, may increase the risk of autism.

A single gene, OTUD7A, may account for most of the features seen in people missing a segment of chromosome 15 known as 15q13.3.

A cannabis gel may ease features of fragile X syndrome, omega fatty acids show promise for autism in two trials, and oxytocin reinforces social behaviors through the brain’s reward pathway.

Mutations that appear in only some of the body’s cells contribute to autism in about 4 percent of people with the condition.

Watch the complete replay of this journal club, which featured two papers on mosaic mutations in autism.

Scientists this week announced the release of nearly 7,000 whole-genome sequences from a collection of families that each have one child with autism.

People with autism aren’t easily surprised, the social camouflage some girls and women with autism use may preclude diagnosis, and autism-related genes are rooted deep in human ancestry.
