Despite these variables, our MSE analyses of MUC1, MUC2 and MUC4 in human pancreatic juice showed high sensitivity and specificity for differentiation among PDAC, gastric-type IPMN, intestinal-type IPMN and other-type IPMN. The gene discussed is MUC2; the disease is pancreatic intraductal papillary-mucinous neoplasm.
