Children with tuberous sclerosis who have seizures as infants are particularly likely to also have developmental delay and autism features.

Probing the function of a protein in a calcium signaling pathway may lead to a diagnostic test for autism and a path toward treatments.

Scientists have discovered more than 100 new proteins at junctions in the brain that dampen neuronal activity.

Mutations in TSC2, a gene typically associated with a syndrome called tuberous sclerosis, are found in many children with autism.

As powerful genetic tools identify increasing numbers of autism genes, scientists are parsing the pool of autism into new syndromes, each with a distinct genetic origin.
