Familial adenomatous polyposis (FAP) is an autosomal dominant disease characterized by the development of numerous adenomatous polyps in the colon and rectum with diverse extracolonic manifestations. Recent genetic advances have lead to the sequencing of the FAP gene, with important implications for screening, diagnosis and follow-up. Appropriate management of probands and at-risk patients is of the utmost importance, as untreated carriers will develop colorectal cancer. Identification of FAP families and tracing of pedigrees represent the most important steps. To this end registries are essential, allowing a comprehensive multidisciplinary approach. They have justified their place by decreasing related morbidity and mortality. An overview and discussion of clinical features and management are presented.
