Older men and women are more likely than young ones to have a child with autism, but this connection is not straightforward.

The number of top autism genes has risen from 65 to 102, based on an analysis of more than 35,000 sequences. And researchers are seeing the first hints of autism risk variants in the regions between genes.

Researchers have monitored the active genome in brain organoids over the course of nearly two years — and may find clues to autism’s roots.

People with autism have more brain-related health problems, such as headaches and epilepsy, than typical people do.

Some men who have an autistic child carry mutations linked to the condition only in their sperm.

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

A new resource details the genetic diversity of people in Asia and may shed light on genetic conditions such as autism.

Autism may stem from a different — and larger — set of genetic mutations in women than it does in men.

The question of autism’s heritability is compelling for researchers and laypeople alike, but many people in both groups misunderstand its definition.

Mutations in a gene called ZNF292 lead to a variety of developmental conditions, including autism and intellectual disability.
