We complemented the above data with GWAS summary statistics on case-control data on DBDs from the recently published Psychiatric Genetics Consortium/iPSYCH consortium meta-analysis, which included data from seven cohorts (Cardiff sample, CHOP cohort, IMAGE-I & IMAGE-II samples, Barcelona sample, Yale-Penn cohort, and the Danish iPSYCH cohort), totaling 3802 cases and 31,305 controls [19].
