  • * Cysts seen by EUS.

  • Tumour location and size of the largest cyst.

  • Mutation score =total number of positive wells with confirmed GNAS mutations by pyrosequencing.

  • § Germline mutation carrier.

  • EUS, endoscopic ultrasonography; HRM, high-resolution melt-curve analysis; IPMN, intraductal papillary mucinous neoplasm; PJS, Peutz–Jeghers syndrome; WT, wild-type.
