Compendium of Cancer Genome Aberrations (CCGA)



The CGC is developing the Compendium of Cancer Genome Aberrations (CCGA), a collaborative project to document genomic aberrations in cancer based on the WHO classification structure as an educational resource for day-to-day use in clinical case interpretation.  Hosted on a wiki platform, the CCGA is designed to provide up-to-date and integrative content, highlighting actionable and diagnostically-important features.



The CCGA is a global collaborative effort to describe clinical context-based knowledge for gene- and chromosome-level abnormalities observed in cancer.


  • Provide a centralized resource of genetic correlates for pathologic entities, structured based on current disease-level WHO classification system, with direct links to significant internal and external site content.
  • Support real-time updating and sharing of clinically relevant content that is peer-reviewed and easily searchable.
  • Engage community experts and their trainees in curating, updating and utilizing content.
  • Include cancer variant knowledge identified through diverse methods and across multiple disciplines.
  • Facilitate building educational content that describes the latest advancements in the field.

We welcome you to join our team and contribute to the CCGA. Please complete a short Volunteer Form and we will be in touch with you shortly.
