Their own facial expressions, tone of voice, and body language may not match what they are saying, making it difficult for others to respond appropriately. Such barriers to communication can isolate children with ASD from their peers.

- Autism Gene Scans Converge on Two Suspect Sites, Two Types of Genetic Risk
- Science Update
Four teams of scientists, using resources supported in part by NIMH, have pinpointed two different sites in the genome, each conferring a different type of genetic risk for autism.
