A causative gene mutation is still undefined in approximately half of patients with hereditary pancreatitis, and no genetic factor has been identified in most patients with sporadic chronic pancreatitis. To identify a pancreatitis-associated gene, we performed a quantitative trait locus (QTL) analysis for the traits of chronic pancreatitis and diabetes mellitus in WBN/Kob rats. We identified two highly significant QTLs for chronic pancreatitis and/or hyperinsulinemia on chromosomes 7 and X. These QTLs were located on completely different chromosomal regions from those of causative genes that have been reported for human chronic pancreatitis: PRSS1, CFTR, and SPINK1. For these QTLs, prevalences of the WBN/Kob allele significantly increased in the rats with chronic pancreatitis. These findings indicate that chronic pancreatitis in WBN/Kob rats is controlled by multiple genes, and a genetic analysis in WBN/Kob rats might be useful for gene targeting for human chronic pancreatitis.
