An upsurge in autism cases diagnosed in the Silicon Valley area of California may be due to genes more common in its high-tech workers, say experts. As many as one in 150 children in the region have some sort of autistic spectrum disorder (ASD), a rate which far outstrips other areas of the US. There has been a 273% increase in the number of autistic children attending 21 regional centers in California between 1987 and 1998.
