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.

A surprising number of genes associated with autism also have links to cancer. Does that mean cancer drugs can treat autism?

Meet the backyard marijuana growers and home chemists who are rushing in where scientists fear to tread.

Children who have both tuberous sclerosis and autism have features nearly identical to those of children with autism alone.

Criss-crossing the globe on a quest for unusual DNA, researchers have discovered a rare mutation that promises insights into both epilepsy and autism — and points to a treatment.

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.

Mice carrying any one of five autism-linked mutations struggle to associate a flash of light with an irritating puff of air. The findings suggest that the mice have trouble integrating information from multiple senses — a skill governed by the cerebellum.

Treatments for fragile X syndrome may be more successful if they block direct targets of the key missing protein, says Eric Klann.
