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.

Web of genes may hold clues for autism treatments
Many of the genes that have emerged as the strongest autism candidates have turned out to regulate the expression of hundreds, if not thousands, of other genes. Within these networks, scientists are homing in on pathways that underlie autism.
