People with an mutation have . mutations increase the risk for colorectal, endometrial and other types of cancer listed in the table below. Mutations in affect another gene called . For this reason, the cancer risks for people with and mutations are similar.
If you or a relative have tested positive for an mutation, we recommend speaking with a genetics expert. They can look at your personal and family medical history to help you understand and decide on a plan for managing your risk.

Other cancers
People with an inherited mutation may have an increased risk for other cancers. The exact risks for the following cancers are unknown:
- pancreatic cancer
- sebaceous skin growths
- female breast cancer
Research on how inherited mutations in the gene affect cancer risk is ongoing.
It is important to note that cancer risks are estimates over the course of a person's lifetime. Your lifetime risk and risk over the next five years will vary depending on:
- current age
- sex assigned at birth
- specific mutation
- personal and family health history
- diet, exercise, lifestyle and other factors
