“NHGRI Genome-Wide Association Study of Venous Thrombosis (GWAS of VTE)” contributed genome-wide genotypes, age and sex data for an additional 1295 control samples. Detailed information about both of these studies can be found at the dbGaP website. The genotype data from these 2638 samples from dbGaP were combined with the 530 CIDR-genotyped unaffected controls, giving a total pre-QC control sample size of 3168.
