Blocking one form of an enzyme implicated in autism eases unusual behaviors and seizures in mice missing a top autism gene.

A collection of rare genetic variants associated with autism and schizophrenia also seem to increase a person’s odds of having attention deficit hyperactivity disorder.

Autistic people who carry mutations in a gene called PTEN have distinct behavioral and motor problems.

A new method scans gene expression in live cells and could help scientists study autism genes.

Researchers have identified a distinctive pattern of gene expression in the white blood cells of young autistic boys.

Mutations in the gene CSDE1 lead to a constellation of developmental delays and conditions, including autism, according to a new study.

Rats missing UBE3A, the gene mutated in people with Angelman syndrome, squeak frequently but tend not to be responsive to the play and squeaks of other rats.

Mice lacking one copy of a gene called DDX3X have developmental delay and sensory, motor and behavioral problems — similar to those seen in people with a mutation in the gene.

Researchers have used a new gene-editing technique to delete a segment of DNA associated with autism and schizophrenia from mouse brain cells.

Turning down the expression of a gene linked to autism leaves zebra finches singing disorganized songs.
