Please note this is a beta version of the ClinGen Evidence Repository. This resource is intended to provide access to variant level evidence used and applied by ClinGen Variant Curation Expert Panels in the classification of variants. In this beta version, the evidence is limited to curation notes and referenced literature (PMIDs).
For general information about ClinGen Expert Panels and Variant Curation please visit: Clinical Domain Working Groups. For specific inquiries regarding a variant classification or evidence curation (e.g. population database queried, segregation counts or other evidence used) or to submit general comments about the evidence repo, please email us.
The resource is undergoing updates and tesing. Should you encounter any issues regarding the data displayed, lack of functionality or other problems, please let us know so we can rectify these accordingly. Your help in this regard is greatly appreciated.
