Dosage Studied

Trypsinogen (PRSS1, PRSS2) copy number gains and regulatory variants have both been proposed to elevate pancreatitis risk through a gene dosage effect. To test the method we investigated the time-course and the dose-response curve for acetylcholine-induced tryps in pancreatic segments.
