Previous studies reported 21 independent GWAS risk loci for SZ (Lam et al., 2019), and we found that 15 of them were also genome-wide significant in the meta-analysis, including the previously known loci at VRK2, CACNA2D2, DOCK3, STAG1, WBP1L and KCNG2 etc. Another four SZ GWAS loci (PPARGC1A, MEAT6, LOC102724623 and PQLC1) were not included in the current meta-analysis as their leading SNPs (or their LD indexed SNPs) were not genotyped or imputed in the BD GWAS sample. The gene discussed is STAG1; the disease is Behcet disease.
