Like so many other events this year, autism’s biggest annual conference — the International Society for Autism Research meeting — was forced to go virtual because of the coronavirus pandemic.

A new study highlights the challenge of distinguishing genetic variants linked to autism from those associated with cognitive development.

Deletions and duplications of long stretches of DNA may increase the likelihood of autism in people who have a mutation in a gene called PTEN.

The many genes implicated in Williams syndrome, a condition related to autism, may all work together to exert their effects on behavior.

A new database cross-checks study participants to avoid double-counting variants linked to autism genes.

The loss of 21 genes on chromosome 3 may substantially raise the risk of autism.

Researchers are studying how a combination of genetic ‘hits’ may contribute to autism’s diversity.

No genetic test can say whether a person has autism, but it may point to a cause for the condition or for any related complications.

Certain repeated stretches of DNA that are linked to the expansion of the primate brain may also enhance autism traits.

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