Interestingly, IPMN-glycolysis pattern 3, which was associated with KRAS c.436G>C and GNAS c.601C>A (from cluster IPMN-P3) in the original cohort, is not found in this data, neither in the dysplastic epithelium, normal epithelium, or nonepithelial regions. Here, GNAS is linked to pancreatic intraductal papillary-mucinous neoplasm.
