Summary Summary


Listen
Peutz-Jeghers syndrome (PJS) is an inherited condition that is associated with an increased risk of growths along the lining of the gastrointestinal tract (called hamartomatous polyps) and certain types of cancer. Most affected people also have characteristic dark blue to dark brown macules around the mouth, eyes, and nostrils; near the anus (perianal); and on the inside of the cheeks (buccal mucosa). PJS is caused by changes (mutations) in the STK11 gene and is inherited in an autosomal dominant manner.[1][2] Management typically includes high-risk screening for associated polyps and cancers.[3]

Symptoms Symptoms


Listen
Peutz-Jeghers syndrome (PJS) is characterized primarily by an increased risk of growths along the lining of the gastrointestinal tract (called hamartomatous polyps) and certain types of cancer. Polyps are most commonly seen in the small intestines; however, they can also develop in the stomach, large intestines and other parts of the body such as the lungs, gall bladder, nose, and urinary bladder. Although these polyps are generally benign (noncancerous), they can be associated with many health problems including anemia, chronic bleeding, bowel obstruction, and intussusception. PJS-related polyps commonly present in adolescence or early adulthood with approximately a third of affected people experiencing symptoms in the first 10 years of life.[1][2]

People with PJS also have a high lifetime risk of developing cancer. Cancers of the gastrointestinal tract (stomach, small intestine, and colon), breast, pancreas, cervix, ovary, uterus and lungs are among the most commonly reported tumors.[1][2] Medscape reference offers more specific information regarding the risks for these cancers and the average age of onset. Please click here to view this resource.

Most affected people also have characteristic dark blue to dark brown macules around the mouth, eyes, and nostrils; near the anus (perianal); and on the inside of the cheeks (buccal mucosa). These spots may also occur on the hands and feet. They commonly appear during childhood and often fade as the person gets older.[1][2]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cause Cause


Listen
Peutz-Jeghers syndrome (PJS) is caused by changes (mutations) in the STK11 gene. STK11 is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in STK11 result in a defective protein that is unable to carry out its normal role. This leads to the development of the polyps and tumors found in PJS.[4]

Some people with PJS do not have mutations in the STK11 gene. In these cases, the cause is unknown.[4]
Last updated: 3/15/2015

Inheritance Inheritance


Listen
Peutz-Jeghers syndrome (PJS) is inherited in an autosomal dominant manner.[1] This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with PJS has a 50% chance with each pregnancy of passing along the altered gene to his or her child.
Last updated: 3/15/2014

Diagnosis Diagnosis


Listen
A diagnosis of Peutz-Jeghers syndrome (PJS) is based on the presence of characteristic signs and symptoms. In people with a clinical diagnosis of PJS, genetic testing of the STK11 gene confirms the diagnosis in approximately 100% of people who have a positive family history and approximately 90% of people who have no family history of PJS.[1]

GeneReviews offers more detailed information regarding the diagnosis of PJS including the clinical diagnostic criteria. Click here to view this resource.

  • I have many dark colored spots on my lips, inside my cheek, and on my gum. These spots developed while I was in my thirties. Although I do not have gastrointestinal symptoms and my family history is negative, my dermatologist has suggested the possibility of Peutz-Jeghers syndrome (PJS). I am concerned about the high incidence of cancer in PJS patients and would like to know if definitive testing is available. See answer
