Finding a mutation linked to autism traits can have life-changing consequences for autistic individuals and their families.

Watch the complete replay of Ivan Iossifov discussing the genetic basis of autism’s features.

An analysis of DNA from more than 20,000 people with autism identifies 12 regions in the genome that harbor inherited risk factors for the condition.

Genetic tests for people with autism are far from routine and don’t always yield results, but the information they offer can change lives.

A newly expanded database of information from people in the United Kingdom provides a detailed picture of genetic diversity.

This year’s list of top papers highlights new dimensions in our understanding of autism genetics and hints at novel treatments.

The largest genetic analysis of postmortem brain tissue to date has yielded maps of when and where genes related to autism are turned on and off throughout life.

In autism research, as in other fields, small sample sizes can lead to false findings. The size of the sample needed for statistical significance depends on the type of study.

Genetic variants across the genome contribute to about 8 percent of the risk for certain developmental conditions — much more than previously thought.

Autism and intelligence share genetic variants, researchers grow Neanderthal mini-brains and see overlap with autism, and maternal diabetes is an autism risk factor.
