 16A -> V (in PCTT; disrupts signal sequence cleavage site; dbSNP:rs202003805). VAR_011693 dbSNP
 22D -> G (in PCTT; increased rate of activation; dbSNP:rs397507442). VAR_011652 dbSNP
 23K -> R (in PCTT; increased rate of activation; dbSNP:rs111033567). VAR_011653 dbSNP
 29N -> I (in PCTT; dbSNP:rs111033566). VAR_006720 dbSNP
 29N -> T (in PCTT; dbSNP:rs111033566). VAR_012712 dbSNP
 54N -> S (in PCTT; associated with Ile-29; the double mutant shows increased autocatalytic activation which is solely due to the Ile-29 mutation; dbSNP:rs144422014). VAR_037908 dbSNP
 79E -> K (in PCTT; Lys-79 trypsin activates anionic trypsinogen PRSS2 2-fold while the common pancreatitis-associated mutants His-122 or Ile-29 have no such effect; dbSNP:rs111033564). VAR_037909 dbSNP
 104L -> P (in PCTT). VAR_011654
 116R -> C (in PCTT; dbSNP:rs387906698). VAR_011655 dbSNP
 122R -> C (in PCTT; suppresses an autocleavage site; dbSNP:rs111033568). VAR_012713 dbSNP
 122R -> H (in PCTT; suppresses an autocleavage site which is probably part of a fail-safe mechanism by which trypsin, which is activated within the pancreas, may be inactivated; loss of this cleavage site would permit autodigestion resulting in pancreatitis; dbSNP:rs267606982). VAR_006721 dbSNP
 137T -> M (in a colorectal cancer sample; somatic mutation; dbSNP:rs117497341). VAR_036299 dbSNP
