ABO and pancreatic neoplasm: Albeit modestly, the risk for pancreatic cancer is also associated with another locus on chromosome 9, the ABO locus in the q34 region, which was the first common pancreatic cancer risk locus [147] and controversially associated with patient survival [148–152] Although the cohort size was too small to reach genome-wide significance, data of Qi et al. [153] strongly suggest that the ABO locus also presents linkage with type 2 diabetes.
