prasad_12_ASD_discovery_cases
Unrelated ASD cases recruited from three Canadian sites (Hospital for Sick Children, McMaster University, and Memorial University of Newfoundland); the majority of cases had been previously genotyped with results published in Marshall et al., 2008 and Pinto et al., 2010. 20 cases from initial cohort of 696 were excluded from further analysis (due to CNVs > 5 Mb).
