Read about different genes that are linked to hereditary cancer, their associated risks and guidelines for screening, preventing and treating cancers in people with inherited mutations in these genes.
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.
FORCE offers many peer support programs for people with inherited mutations.
- Our Message Boards allow people to connect with others who share their situation. Once registered, you can post on the Diagnosed With Cancer board to connect with other people who have been diagnosed.
- Our Peer Navigation Program will match you with a volunteer who shares your mutation and situation.
- Our moderated, private Facebook group allows you to connect with other community members 24/7.
- Check out our virtual and in-person support meeting calendar.
- Join one of our Zoom community group meetings.
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.
- NCT03174574: Two Cancers, One Gene (TCOG). The TCOG study is looking at why some people in families with CDKN2A mutations develop melanoma or pancreatic cancer. The overall goal of this study is to understand the factors that increase pancreatic cancer and melanoma in high-risk families.
