Familial adenomatous polyposis (FAP) is an inherited condition that affects the gastrointestinal tract. FAP leads to hundreds or thousands or polyps inside the colon or rectum. This condition is also known as hereditary polyposis of the colorectum, familial polyposis and Gardner’s syndrome.
The polyps begin to appear during teen years and often become cancerous by 40 years of age if left untreated. People with FAP have a 50 percent chance of passing the condition on to their children.
Genetic counseling is available and recommended for individuals with FAP and their families. A genetic counselor can explain how FAP is inherited and which family members are at risk for developing FAP and give you information regarding genetic testing.
