Identification of a novel pancreatitis-associated missense mutation, R116C, in the human cationic trypsinogen gene (PRSS1).

Over the past 5 years, several gain-of-function missense mutations in the human cationic trypsinogen gene (PRSS1, OMIM 276000) have been associated with hereditary and/or sporadic pancreatitis. This study reports a new pancreatitis-associated mutation--R116C (CGT > TGT: c.346C > T)--in the gene.
