Ancestry-matched controls (n=720) were collected in parallel with their respective cases for the French-Canadian (n=269), German (n=224), South African (n=188), and Dutch (n=39) samples. These controls were screened for TS and OCD and genotyped with cases on the Illumina Human610-Quadv1_B20,21, (referred to here as ‘Hap610 controls’).
