Biostatistics approach to genetics yields new clues to roots of autism

Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent ?pruning? of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.
