Tackling the genetic complexity of some neurological conditions is no easy task, but researchers have begun to unravel the heritable components of autism spectrum disorders (ASDs) through studies of affected families. By analyzing the DNA of 1600 families with at least two affected individuals, the Autism Genome Project Consortium, a group of more than 120 collaborators from 50 centers in North America and Europe, performed the largest genome scan to date for ASDs, finding clues to autism susceptibility (Autism Genome Project Consortium. Nat Genet. doi:10.1038/ng1985 [published online February 18, 2007]).
