PRSS1<sup>A16V</sup> germline mutation is common in a cohort of intraductal papillary mucinous neoplasms of the pancreas

Listen to this summary

The authors aimed to investigate the genetic alterations associated with intraductal papillary mucinous neoplasms (IPMNs) of the pancreas, specifically exploring the role of the PRSS1<sup>A16V</sup> germline mutation in these lesions. Their findings revealed that this mutation is present in a subset of IPMNs and is linked to clinical symptoms and imaging features indicative of early chronic pancreatitis, suggesting that inflammation may play a role in the biology and heterogeneity of these neoplasms.
