Neurons from people with autism may have an unusual pattern of chemical tags that turn genes on and off.

Existing genome scans do not detect many of the DNA variants that underlie behavioral problems.

A new inventory of proteins reveals their levels in seven brain regions from infancy through adulthood.

The heritable factors that underlie autism may overlap with those that influence unusual sensory responses.

The way children view both social and nonsocial situations may be determined at least in part by their genes.

Infants who have neurofibromatosis, a genetic condition linked to autism, show motor difficulties and communication delays at 10 months of age.

Success in a small clinical trial of spinal muscular atrophy suggests gene therapy might treat single-gene conditions related to autism.
