Cancer risk associated with inherited CDK2NA mutations

If you have tested positive for an inherited CDKN2A mutation, we recommend that you speak with a genetics expert  who can look at your personal and family history of cancer and can help you choose the best plan for managing your cancer risk.

  • People who have a CDKN2A mutation have between a 28% - 76% lifetime risk of developing melanoma depending on other factors, including family history, where they live and other genetic factors. The lifetime risk for melanoma in someone without a mutation is about 2.5 percent. People with a CDKN2A mutation:
    • often develop melanomas at a young age (before the age of 50).
    • may develop two or more melanomas during their life.  
  • People with a CDKN2A mutation have up to a 17% percent lifetime risk of developing pancreatic cancer. 
  • Risks may be higher for people with close relatives who have been diagnosed with melanoma or pancreatic cancer. 
  • Some studies suggest that smoking may increase cancer risks in people with CDKN2A mutations.

NCT02665195: Registry Of MultiPlex Testing (PROMPT). PROMPT is an online research registry. The goal of PROMPT is to help researchers to better understand the risks that are linked to mutations in less well-studied genes. People with inherited mutations can enroll in PROMPT to help researchers learn more about cancer risks.

  • NCT03250078: Pancreatic Cancer Screening Study for High Risk People. The purpose of this study is to screen and detect pancreatic cancer and precancer in people with a strong family history of pancreatic cancer, or people with an and at least one first- or second-degree relative with pancreatic cancer. This includes people with a CDKN2A .
  • NCT02206360: Pancreatic Cancer Early Detection. This is a study looking at esophageal as a screening for pancreatic cancer in high risk individuals. The study will enroll people with an inherited risk for cancer due to a or CDKN2A mutation.
