In this study, we selected autoantibodies with frequency > 0.5% (β2-GPI, SMA, ACL, AMA, anti SS-B, anti-ds DNA, anti-ss DNA, AHA, anti-RNP, anti-proteinase 3 IgG antibody) in non-AIP CP patients as search objects to compare and analyze, which were listed in Table 2. This evidence concerns the gene SMN1 and autoimmune pancreatitis.
