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

Scientists this week announced the release of nearly 7,000 whole-genome sequences from a collection of families that each have one child with autism.

People who carry risk factors for autism but do not have the condition tend to have slightly fewer children than average, and have them later in life.

A large study of minute mutations in people with developmental conditions, including autism, has uncovered 200 potential risk genes.

Researchers in Oregon edit human embryos, prenatal antidepressants may play a role in autism risk, and gut microbiota are associated with early cognition.

About 8 percent of non-inherited mutations in people with autism occur in only some of the body’s cells, according to a study of 20,000 people.

Where do we stand in our understanding of autism genetics — and what major questions remain? A molecular biologist supplies answers in stanzas.

Families need more support from researchers in order for their heroic efforts to be optimally effective.

Autism researchers’ top priority should be shifting their focus to finding treatments for severe forms of the condition.

We finally have access to whole-genome sequences from people with autism. But before we can properly interpret these data, we need to know what we’re looking for.
