The ClinGen Gene Curation working group has developed a framework to standardize the approach to determine the clinical validity for a gene-disease pair. This framework:

  • Defines the criteria needed to assess clinical validity
  • Describes the evidence supporting a gene-disease association in a semi-quantitative manner, and
  • Allows curators to use this information to methodically classify the validity of a given gene-disease pair.

This framework is currently optimized for genes associated with monogenic Mendelian disorders of reasonable penetrance.  It is distinct from, and not meant to be a substitute for, the well-established statistical thresholds used for genome-wide association studies or validated methods to define multifactorial disease risk.  Future iterations will expand the framework to consider the evaluation of oligogenic or multifactorial conditions.

Clinical Validity Classifications

The Clinical Validity Classifications are used to qualitatively describe the strength of evidence documenting a gene-disease association.  Note: these terms do not reflect the effect size or relative risk attributable to variants in a particular gene.
