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

Some genes associated with autism may influence the thickness of the cerebral cortex, the brain’s outer layer.

Mice lacking CNTNAP2, a gene strongly linked to autism, are acutely sensitive to pain.

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

Mice missing TAOK2, a gene in a segment of chromosome 16 linked to autism, have big brains, immature neuronal junctions and asocial behavior.

A low dose of a drug used to treat lymphoma may ease social problems in some forms of autism.
