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.
General information for people with inherited mutations
Both men and women can carry a mutation in the gene.
Inherited mutations in the gene are associated with . Other names for include Hereditary Nonpolyposis Colorectal Cancer ().
People with inherited mutations have increased risk for many cancers but particularly cancers of the large intestine (the colon and the rectum) and uterus (endometrium). See our Cancer Risk section for more information. There are guidelines for screening and prevention for certain cancers in people with an mutation. Clinical trials may also be available for people who test positive for an mutation. See our Risk Management section for more information about screening and prevention options.
People with an inherited mutation who have been diagnosed with cancer may qualify for specific treatments or clinical trials. Visit our Cancer Treatment section for more information about treatment for people with an mutation.
Children who inherit a mutation from both their mother and father can have a rare syndrome known as “constitutional (CMMRD),” which can cause high risks of various cancers in childhood and young adulthood. See our Other Considerations section for more information about this disease.
The (PMS1 homolog 2, mismatch repair system component) gene is located on chromosome 7. The gene protein plays an important role in repairing damage.
