By including more than twice the number of case patients than were included in previous Japanese or Chinese GWASs, as well as by using imputed SNP data, we replicated the majority of significant loci discovered for pancreatic cancer in the PanScan and PanC4 consortia GWASs (Supplementary Data 10), including the well-established ABO locus. This evidence concerns the gene ABO and familial pancreatic carcinoma.
