Abbreviations: GWAS, genome-wide association study; PDAC, pancreatic ductal adenocarcinoma; SNP, single-nucleotide polymorphism.
The analysis (N=8,384 cases and 11,955 controls) was adjusted for age, sex, study, geographic region, and the top eigenvectors for the PanScan studies and age, sex, and the top eigenvectors for the PanC4 studies.
These SNPs are within +/− 500kb genomic regions around index-SNPs and correlated with index-SNPs at r2 > 0.80.
Results were obtained after excluding +/− 500kb genomic regions of 20 PDAC GWAS risk signals.
