Elastase 3B mutation links to familial pancreatitis with diabetes and pancreatic adenocarcinoma

Abstract

Although improvements in genetic analysis have greatly enhanced our understanding of the mechanisms behind pancreatitis, it continues to afflict many families for whom the hereditary factors remain unknown. Recent evaluation of a patient with a strong family history of pancreatitis prompted us to reexamine a large kindred originally reported over 50 years ago with an autosomal-dominant inheritance pattern of chronic pancreatitis, diabetes, and pancreatic adenocarcinoma. Whole-exome sequencing analysis identified a rare missense mutation in the gene encoding pancreas-specific protease elastase 3B (CELA3B) that cosegregates with disease. Studies of the mutant protein in vitro, in cell lines, and in CRISPR-Cas9–engineered mice indicate that this mutation causes translational upregulation of CELA3B, which, upon secretion and activation by trypsin, leads to uncontrolled proteolysis and recurrent pancreatitis. Although lesions in several other pancreatic proteases have been previously linked to hereditary pancreatitis, to our knowledge, this is the first known instance of a mutation in CELA3B and a defect in translational control contributing to this disease.

Problems with a PDF?

This file is in Adobe Acrobat (PDF) format. If you have not installed and configured the Adobe Acrobat Reader on your system.

Having trouble reading a PDF?

PDFs are designed to be printed out and read, but if you prefer to read them online, you may find it easier if you increase the view size to 125%.

Having trouble saving a PDF?

Many versions of the free Acrobat Reader do not allow Save. You must instead save the PDF from the JCI Online page you downloaded it from. PC users: Right-click on the Download link and choose the option that says something like "Save Link As...". Mac users should hold the mouse button down on the link to get these same options.

Having trouble printing a PDF?

  1. Try printing one page at a time or to a newer printer.
  2. Try saving the file to disk before printing rather than opening it "on the fly." This requires that you configure your browser to "Save" rather than "Launch Application" for the file type "application/pdf", and can usually be done in the "Helper Applications" options.
  3. Make sure you are using the latest version of Adobe's Acrobat Reader.
