Core tip: Pancreatitis is a progressive inflammatory disease. Though the pancreas has adequate protection against environmental and metabolic stress, if the magnitude of this stress exceeds the threshold which the organ can handle, it leads to pathologic effects. Although genetic variables have been identified that affect the function of pancreas, namely polymorphisms in serine protease inhibitor kazal type 1 (SPINK1), polymorphisms in cationic trypsinogen (PRSS1) and Chymotrypsinogen C (CTRC) genes in the acinar cells and cystic fibrosis trans-membrane conductance regulator (CFTR), calcium sensing receptor (CASR genes) in the ductal cells leading to pancreatitis, off late many genetic factors outside of the “intra-pancreatic trypsin regulatory mechanism” have been identified for their role in pancreatitis. This review is an update on the genetic aspects of acute and chronic pancreatitis.
