[Hereditary pancreatitis].

Hereditary pancreatitis (HP) is an autosomal dominant inherited disease characterized by recurrent episodes of pancreatitis often beginning in childhood, a family history of at least 2 other affected members, and the absence of known etiologic factors. The discovery of mutations in cationic trypsinogen gene (PRSS1) in HP not only provided insights into the molecular mechanisms of pancreatitis, but also opened a new era in the field of chronic pancreatitis. The detection of mutations in serine protease inhibitor, Kazal type 1 (SPINK1) and CFTR in patients with hereditary or idiopathic chronic pancreatitis has placed the emphasis on the importance of genetic mutations in pancreatitis. Because the estimated cumulative risk of pancreatic cancer development in hereditary pancreatitis is nearly 40%, screening tests are important in selected cases. There are no specific medical therapies recommended in patients with HP. Registration of patients with Nationwise Registries is essential if management strategies are to be improved and genetic research to be continued.
