SPINK1
The Spink1 Gene: A Critical Player in Pancreatic Function and Disease
Description
The spink1 gene, located on chromosome 7q21.3, encodes a serine protease inhibitor known as pancreatic secretory trypsin inhibitor (PSTI). This protein plays a crucial role in the regulation of pancreatic function and protection against enzyme-induced injury.
Associated Diseases
Mutations in the spink1 gene have been linked to various pancreatic diseases, including:
- Chronic pancreatitis: Mutations in spink1 are the most common genetic cause of chronic pancreatitis, characterized by persistent inflammation and fibrosis of the pancreas.
- Pancreatic cancer: spink1 mutations have been associated with an increased risk of pancreatic cancer, a highly aggressive and often fatal malignancy.
Did you Know ?
Approximately 25% of individuals with chronic pancreatitis have a mutation in the spink1 gene. This mutation is particularly common in people of European descent.
