What is the official name of the SPINK1 gene?

The official name of this gene is “serine peptidase inhibitor, Kazal type 1.”

SPINK1 is the gene's official symbol. The SPINK1 gene is also known by other names, listed below.

What is the normal function of the SPINK1 gene?

From NCBI Gene (

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]

From UniProt (ISK1_HUMAN) (

Serine protease inhibitor which exhibits anti-trypsin activity (PubMed:7142173). In the pancreas, protects against trypsin-catalyzed premature activation of zymogens.In the male reproductive tract, binds to sperm heads where it modulates sperm capacitance by inhibiting calcium uptake and nitrogen oxide (NO) production.

How are changes in the SPINK1 gene related to health conditions?

Genetics Home Reference provides information about hereditary pancreatitis, which is associated with changes in the SPINK1 gene.
UniProt (ISK1_HUMAN) ( provides the following information about the SPINK1 gene's known or predicted involvement in human disease.

Pancreatitis, hereditary (PCTT): A disease characterized by pancreas inflammation, permanent destruction of the pancreatic parenchyma, maldigestion, and severe abdominal pain attacks. Disease susceptibility is associated with variations affecting the gene represented in this entry.

Tropical calcific pancreatitis (TCP): Idiopathic, juvenile, nonalcoholic form of chronic pancreatitis widely prevalent in several tropical countries. It can be associated with fibrocalculous pancreatic diabetes (FCPD) depending on both environmental and genetic factors. TCP differs from alcoholic pancreatitis by a much younger age of onset, pancreatic calcification, a high incidence of insulin dependent but ketosis resistant diabetes mellitus, and an exceptionally high incidence of pancreatic cancer. Disease susceptibility is associated with variations affecting the gene represented in this entry.

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the SPINK1 gene.
  • Hereditary pancreatitis
  • Tropical calcific pancreatitis (, a catalog designed for genetics professionals and researchers, provides the following information about the SPINK1 gene and its association with health conditions.

Where is the SPINK1 gene located?

Cytogenetic Location: 5q32

Molecular Location on chromosome 5: base pairs 147,824,580 to 147,839,231

(Homo sapiens Annotation Release 107, GRCh38.p2) (NCBI (

The SPINK1 gene is located on the long (q) arm of chromosome 5 at position 32.
