In another study of PCF from 10 intestinal-type IPMNs, sequencing detected 10 of 13 mutations present in matched IPMN tissue, including 6 of 7 GNAS mutations and each of 3 KRAS mutations (Berger et al. 2016). The gene discussed is KRAS; the disease is pancreatic intraductal papillary-mucinous neoplasm.
