Children who have both tuberous sclerosis and autism have features nearly identical to those of children with autism alone.

Techniques used in behavioral interventions could help scientists scan the brains of children who have both autism and intellectual disability.

Mutations in an autism-linked gene called AUTS2 do not cause the condition’s core social features, according to the most comprehensive clinical portrait to date.

Criss-crossing the globe on a quest for unusual DNA, researchers have discovered a rare mutation that promises insights into both epilepsy and autism — and points to a treatment.

Clinicians are underdiagnosing autism in children from low-income families and minority groups — setting back their potential to benefit from therapy.

Mutations in a gene called POGZ lead to a constellation of traits, including a small head, developmental delay and, often, autism.

After a steady climb since 2000, the prevalence of autism among school-age children appears to have stalled at 1 in 68.

Most children who have both autism and intellectual disability take their first steps on time or earlier than those with other conditions.

A third strain of mice carrying an autism-linked mutation captures the nuances of this structural mutation in people.
