Lowered expression of a gene called DDHD2 may increase a person’s likelihood of having autism, according to a new analysis.

Some of the inherited variants implicated in autism also increase the odds of schizophrenia, bipolar disorder, depression or attention deficit hyperactivity disorder.

A new analysis of nearly 40,000 people pinpoints 48 genetic variants that may determine the volume of certain brain areas.

A collection of rare genetic variants associated with autism and schizophrenia also seem to increase a person’s odds of having attention deficit hyperactivity disorder.

A new method enables researchers to test algorithms for spotting genes that contribute to a trait or condition.

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.

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