Genes affected

SPINK1 (HGNC:11244): (serine peptidase inhibitor Kazal type 1) The protein encoded by this gene is a trypsin inhibitor, which is secreted from pancreatic acinar cells into pancreatic juice. It is thought to function in the prevention of trypsin-catalyzed premature activation of zymogens within the pancreas and the pancreatic duct. Mutations in this gene are associated with hereditary pancreatitis and tropical calcific pancreatitis. [provided by RefSeq, Oct 2008]

SPINK1 Gene-Disease associations (from GenCC):

• hereditary chronic pancreatitis

  Inheritance: AD, Unknown Classification: STRONG, SUPPORTIVE, NO_KNOWN Submitted by: Orphanet, Labcorp Genetics (formerly Invitae), PanelApp Australia
