A rare condition marked by a sudden and profound loss of skills is biologically distinct from other forms of autism.

Whether a gene should be considered a ‘novel candidate’ for autism depends not just on whether it’s been linked to the condition before, but on the strength of that link.

A February study that tied several new genes to autism contained a large statistical error, according to a report from 14 independent researchers; the original team is working on issuing a correction.

Mutations in a gene called TRIP12 — which is involved in tagging proteins for destruction — can lead to intellectual disability, language delay and autism.

Most children with a rare autism-linked mutation develop baby teeth one to two years earlier than usual.

As many as one in three rare mutations seen in people with autism may have nothing to do with the condition.

An analysis of whole genomes from more than 5,000 people has unearthed 18 new candidate genes for autism.

Neuroscientists should not forget that brains have owners, a new genetic database makes its debut, and the intense interests of people with autism offer opportunities.
