Spontaneous genetic mutations contribute to autism in 30 to 39 percent of all people with the condition, and 52 to 67 percent of autistic children whose siblings do not also have the condition.

A large, whole-genome sequencing study of families yields insights into ultra-rare genetic variants that contribute to autism.

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.
