I think so far, when I hear of the new effort and SPARK, it's exciting. The SPARK I worry a little bit about, if this is appropriate. Because I think the key to understanding autism spectrum disorders is phenotype. What is the behavior like? And if the behavior is done lightly or superficially, then no amount of genes are going to lead to a breakthrough, I think. SPARK and whatever the other initiatives are, have to develop good, rigorous phenotypic measures. Right now, of necessity they're done very quickly by phone, and is that going to be good enough to study something as complex as behavioral deficits? I don't know, I'm eager to find out.
