Even in identical twins (identical genes) manifestation isn't 100%.
Obv. it's a start to look at genes but I'd hope it doesn't lead to neglecting other interventions. Its the same with autism they seem to find a new gene every week...so what? Until it leads to treatment research into environment may yield results quicker.
EDIT: It now seems autism is often caused by a lot of changes in common genes, rather than changes in just a few.
