Ten potential pathogenic mutations (in the SERPINB2-, CNTNAP4-, DENND4B-, DPP4-, FGFBP2-, MIGA2-, POLE-, SNRNP40-, TOP2B- and ZDHHC18 genes) could be identified and confirmed in individual cases, yet no mutation was observed in more than one of the 50 analysed cases (including also chronic pancreatitis). The gene discussed is SERPINB2; the disease is chronic pancreatitis.
