Video Summary

Familial adenomatous polyposis (FAP) is a rare, autosomal dominant condition characterized by the development of many polyps in the colon and rectum. These polyps can become cancerous over time, leading to a high risk of developing colorectal cancer. Surgery is often recommended to remove the polyps and prevent cancer from developing.

FAP is caused by mutations in the adenomatous polyposis coli (APC) gene. This gene normally helps to suppress tumor growth in the colon. When it is mutated, this function is lost, resulting in an increased risk of developing tumors. FAP can be diagnosed through genetic testing.
