The GenCC Database and Marker Paper are Now Available

We are pleased to announce the launch of the Gene Curation Coalition (GenCC) Database (DB). The GenCC DB provides information pertaining to the validity of gene-disease relationships, with a current focus on Mendelian diseases. Curated gene-disease relationships are submitted by GenCC member organizations. The GenCC comprises organizations that currently provide online resources (e.g. ClinGen, DECIPHER, Genomics England PanelApp, OMIM, Orphanet, PanelApp Australia, TGMI’s G2P), as well as diagnostic laboratories that have committed to sharing their internal curated gene-level knowledge (e.g. Ambry, Illumina, Invitae, Myriad Women’s Health, Mass General Brigham Laboratory for Molecular Medicine). Our Flagship manuscript, which describes the formation of the database and the standardization of gene disease validity terms is now available from Genetics in Medicine.

GenCC Projects

Gene Validity Term Delphi Survey

To harmonize terms describing gene-disease validity, the GenCC used a Delphi method to survey both members of our GenCC organizations and the international genetics community.

A short introductory video describing the survey can be found here

Terms that were agreed upon are “Definitive, Strong, Moderate, Limited, Disputed Evidence, Refuted Evidence, Animal Model Only, and No Known Disease Relationship”.

Read about our results in the ACMG abstract and the slides presented at CCG 2019.

All member groups will now use or map to relevant harmonized terms in their curation work.

Icon - Hgnc Stable Gene Symbols

HGNC partners with GenCC and is working to stabilize gene symbols

Changes to gene symbols can be confusing and disruptive, especially when that gene is associated to a known phenotype, and may have been quoted in many publications, listed in testing panels, or even be used by a patient support group. The HGNC, who assigns gene symbols and names to all human genes, is aware of the potential widespread impact symbol changes can have. GenCC is collaborating with the HGNC to ensure the long-term stability of gene symbols. Every gene with a curated disease association will be reviewed by the HGNC to check that there is nothing misleading, incorrect or offensive in the nomenclature. Any problematic gene symbols may be updated in line with revised HGNC guidelines, following consultation with the research community. After they have been reviewed gene symbols are marked as ‘stable’ on the HGNC website. It is hoped that some necessary change now will mean fewer changes in the future, as well as improved communication and data retrieval for everyone. HGNC have already stabilized the symbols of over 2000 genes and over 1000 of these have GenCC disease curations.
