Our primary samples are from the AGRE and NIMH Repositories. Replication with Affymetrix technology included NIMH controls, families collected by members of the Autism Consortium, and families ascertained from Montreal. Replication with Sequenom technology included the Autism Genome Project, Finnish, and Iranian subsets of Autism Consortium investigator-collected families. Details of the ascertainment for each sample collection, genotyping, and quality control processes can be found in Methods.
