The Clinical Genome (ClinGen) Resource

ClinGen logo



Medical and research centers are increasingly sequencing exomes or whole genomes of patients. However, identifying sequence variants relevant to disease is difficult.  As a result, information on few genomic variants is used in clinical practice. One factor that limits the clinical use of variant information is the lack of an openly accessible knowledge base that captures genetic variants, their phenotypic and functional effects, and other clinical information. The Clinical Genome Resource (ClinGen) aims to collect phenotypic and clinical information on variants across the genome, develop a consensus approach to identify clinically relevant genetic variants, and disseminate information about the variants to researchers and clinicians.  This resource is essential for advancing the goals of implementing genomics in clinical care and will improve the understanding of phenotypic and functional effects of genetic variants and their clinical value.
ClinGen investigators are developing standard approaches for sharing genomic and phenotypic data provided by clinicians, researchers, and patients through centralized databases, such as ClinVar, and are working to standardize the clinical annotation and interpretation of genomic variants.  Working groups are implementing evidence-based expert consensus methods to curate the clinical validity and medical actionability of genes and variants.   Experts in the areas of cardiovascular disease, pharmacogenomics, hereditary (germline) cancer, somatic cancer, and inborn errors of metabolism have been brought together to assist in these curation efforts.  ClinGen also aims to develop machine-learning algorithms to improve the throughput of variant interpretation and to improve understanding of variation in diverse populations as it relates to interpreting genetic test results.  Lastly, ClinGen will disseminate the collective knowledge and resources for unrestricted use in the community and for use in EHR ecosystems.

Goals of ClinGen
  • Share genomic and phenotypic data through centralized databases for clinical and research use.
  • Standardize clinical annotation and interpretation of variants.
  • Improve understanding of variation in diverse populations.
  • Develop machine-learning algorithms to improve the throughput of variant interpretation.
  • Implement evidence-based expert consensus for curation of clinical validity.
  • Assess the 'medical actionability' of genes and variants to support their use in clinical care systems
  • Disseminate the collective knowledge/resources and ensure EHR interoperability.

ClinGen Principal Investigators and Their Roles in the ClinGen Consortium

 The following groups are receiving grants:
  • Heidi L. Rehm, Ph.D., Brigham and Women's Hospital, Boston; David H. Ledbetter, Ph.D., and Christa L. Martin, Ph.D., Geisinger Health System, Danville, Pa.; 

    This group is developing standard formats for gathering and depositing data into ClinVar. It will work with clinical laboratories and with specific gene databases to facilitate their submissions to ClinVar and to reduce discrepancies in variant classification.  They have also created GenomeConnect, a patient registry, to help people share de-identified genetic and health information with researchers and connect them with other patients.
  • Jonathan S. Berg, M.D., Ph.D, and James P. Evans, M.D., Ph.D, University of North Carolina, Chapel Hill
    David H. Ledbetter, Ph.D., Geisinger Health System, Danville, Pa.
    Michael S. Watson, Ph.D., American College of Medical Genetics and Genomics, Bethesda, Md.

    This group is defining categories of clinical relevance and medical actionability for genes and variants. They have organized clinical domain working groups with experts in hereditary (germline) cancer, somatic cancer, cardiovascular disease, inborn errors of metabolism, and pharmacogenomics to focus on evaluating variants for clinical relevance.  Lastly, they are exploring ways to integrate this information into electronic health records.
  • Carlos D. Bustamante, Ph.D., Stanford University, Palo Alto, Calif.
    Sharon E. Plon, M.D., Ph.D., Baylor College of Medicine, Houston

    This group is working closely with the other grants to develop a robust curation system to analyze the clinical validity of gene-disease associations and to implement the ACMG guidelines for interpreting sequencing variants.  The team is developing the ClinGen Knowledge Base (ClinGenKB) and investigating the feasibility of a controlled-access case-level genetic repository.
