One subgroup of IPNB represented the 'biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas' (biliary-IPMN), and showed unique features reminiscent of IPMN, such as macroscopic and microscopic mucin hypersecretion, an intestinal cell lineage, GNAS mutation, and RNF43 mutation.

Some IPNBs develop via a common oncogenic signaling pathway, and others, particularly those of intestinal type, frequently show GNAS mutations, as in IPMN.

These results indicate that mutations in GNAS and KRAS, the expression of EGFR and pMAPK, the nuclear β-catenin, SMAD4 loss, and TP53 overexpression may be relevant for assessing the clinical course of IPMN, including its progression into different morphological types, invasion, and prognosis.

These results indicate that RNF43 mutation might cause downregulation of the expression of ring finger protein 43 and play a crucial role and associate synergistically with GNAS mutation during development of intraductal papillary mucinous neoplasm of the pancreas.

GNAS mutations were detected in secretin-stimulated pancreatic juice samples of 50 of 78 familial and sporadic cases of IPMN(s) (64.1%), 15 of 33 (45.5%) with only diminutive cysts (<5 mm), but none of 57 disease controls.
