The majority of individuals diagnosed with PJS have an affected parent. It is caused by mutations in the serinethreonine kinase 11 gene LKB1 STK11.

Peutz-Jeghers syndrome is a rare autosomal dominant hereditary polyposis syndrome defined by gastrointestinal hamartomas and mucocutaneous pigmentations caused by a germline mutation in the serine threonine kinase 11 or liver kinase B1 STK11LKB1 genes. The growths called hamartomatous polyps usually grow in the small intestine.
