Amid the vast genetic complexity of autism — more than 1,200 implicated risk genes — a research team at the Institute for Basic Science has found that biological diversity may not mean biological chaos. By mapping gene activity across thousands of mouse brain samples, Professor Kim Eunjoon and colleagues discovered that radically different mutations tend to converge on one of just two opposing molecular states in the brain, suggesting that the many roads into autism may lead to a smaller number of shared destinations. The finding does not rewrite the clinical picture of autism, but it quietly
