Genetic sequences from nearly 53,000 people with autism, developmental delay or intellectual disability reveal strong ties to 98 genes.

Brothers and sisters of people with autism are both about two to three times more likely than the general population to have an autistic child themselves.

An analysis of whole-genome sequences from nearly 500 families has implicated 16 new genes in autism.

A re-analysis of data yields an increased estimate for the genetic contribution to autism, how the environment might contribute to autism is hard to pin down, and students on the spectrum describe the benefits of using technology at school.

Some variants in mitochondrial DNA are more common than others in autism, cognitive therapy reduces anxiety for people on the spectrum, and maternal fever in the third trimester is tied to autism risk.

Children with autism are genetically more similar to one another than to a group of unaffected siblings.

A Tampa clinic goes rogue with fecal transplants, autism’s genetic ancestry traces to our deep past, and the U.S. Supreme Court revives the travel ban.

Large autism-linked mutations tend to be inherited in families with a history of the condition. By contrast, they often arise spontaneously in families with a single affected person.

Researchers are launching a new project that aims to collect genetic information from 50,000 people with autism, along with their relatives.
