What makes a gene an autism candidate? Not everyone agrees

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.

Genetics first: A fresh take on autism’s diversity

Each child with autism is different from the next. One approach rapidly gaining momentum makes sense of this diversity by grouping children together based on their genetics, then looking for patterns in their symptoms. The long-term aim: personalized treatments for each subtype of autism.
