Similarly, no deaths have occurred in patients with GNAS mutant status (p = 0.025), as seen in Figure 1B. A comparison of the impact of GNAS mutational status on the survival of the entire cohort, including all IPMN cases (invasive and non-invasive, n = 39), is shown in Figure 2. Here, GNAS is linked to pancreatic intraductal papillary-mucinous neoplasm.
