Vision Statement

The vision of the CGA-IGC is to eliminate morbidity and early mortality of hereditary gastrointestinal cancers.

Mission Statement

The mission of the CGA-IGC is to advance science and clinical care of inherited gastrointestinal cancers through research and education as the leading authority in the Americas. Through this mission, the CGA-IGC offers the following:

  • Education regarding the clinical management and molecular genetics of inheritegastrointestinal cancer to physicians, allied healthcare professionals, patients, and their families.

  • Access to collaborative trials and studies.

  • Resources for developing new hereditary registries and supporting their registries

  • A forum for exchange of ideas.

  • Multidisciplinary expertise in clinical care, healthcare policy, and research related to hereditary gastrointestinal cancer.

CGA-IGC Commitment to Justice, Equity, Diversity, and Inclusion


The Collaborative Group of the Americas on Inherited Gastrointestinal Cancer (CGA-IGC) promotes diversity and inclusiveness throughout the organization including in its membership, governance, and education programming.  The CGA-IGC also recognizes the importance of advancing health equity in patient care in achieving our core mission as an organization.
