To see all protocols that comply with the WHO Essential Medicine List 

This fact sheet contains general information about Juvenile Polyposis syndrome (JPS). Each person should see a genetic service for further information and advice.

Key Points

  • People with JPS have an increased chance of developing multiple polyps in the bowel and stomach. If these are left untreated, bowel (colorectal) or stomach cancer can develop.
  • People with JPS due to a faulty SMAD4 gene may also have a condition known as Hereditary Haemorrhagic Telangiectasia (HHT).
  • Family members (including children) can be referred to a genetic service where experts can provide information, advice and support about their chance of developing cancer and the option of genetic testing.
