Families of children with mutations in a gene called SYNGAP1 have spurred research into the effects of the mutations on people — and how to treat them.

A new method enables researchers to test algorithms for spotting genes that contribute to a trait or condition.

The timing of treatment is crucial for conditions related to autism — and more so for some conditions than for others.

Mice that lack a segment of chromosome 22 — a mutation associated with autism — have unusually sparse connections between brain regions.

New versions of the DNA editor CRISPR enable scientists to turn off specific genes in rats, detect mutations in human tissue and delete segments of the genome.

Genes associated with autism are ancient, and mutations in them have wide-ranging effects on the body, indicating their importance.

Mice colonized with gut microbes from some autistic boys show behaviors like those of the boys.

Spontaneous mutations that occur between genes may be as important in autism as those within genes.

An array of minute beads enables researchers to build precise maps of gene expression in the brain.

A set of neurons involved in complex cognitive functions may play a central role in autism.
