Genes affected

STK11 (HGNC:11389): (serine/threonine kinase 11) The protein encoded by this gene is a serine/threonine kinase that regulates cell polarity and energy metabolism and functions as a tumor suppressor. Mutations in this gene have been associated with the autosomal dominant Peutz-Jeghers syndrome, as well as with skin, pancreatic, and testicular cancers. [provided by RefSeq, May 2022]

STK11 Gene-Disease associations (from GenCC):

• familial pancreatic carcinoma

  Inheritance: AD Classification: DEFINITIVE Submitted by: G2P
• Peutz-Jeghers syndrome
