Benefits of diets for autism features remain unproven, variants of the same DNA region make brains big or small, and STAT announces a new CRISPR tracker.

To find variants between genes that contribute to autism, researchers may need thousands more whole genomes than they have now.

Some children with autism inherit rare mutations in noncoding DNA from their unaffected fathers.

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

Autism and attention deficit hyperactivity disorder often coincide, but the search for common biological roots has turned up conflicting evidence.

Roughly one in five children who has an extra piece of chromosome 7 also meets the criteria for an autism diagnosis.

Neurons derived from people with mutations linked to autism display diverse abnormalities that may help explain the origins of these individuals’ features.

The male-dominated sex bias in autism is reversed in a related syndrome, a researcher’s gender could influence her study’s outcome, and an award-nominated ad featuring a young man with autism draws criticism.

Deletions within a specific segment of chromosome 22 may raise the risk of autism.

A pruning protein reshapes neurons, culture should be a consideration in trials of autism treatments, and another U.S. state adds autism to the list of indications for medical cannabis.
