ClinGen variant curation interface workshops: Training variant scientists on an international platform

Introduction: The Clinical Genome Resource (ClinGen) is creating a central resource of clinically relevant genetic knowledge to improve genomic medicine. Dissemination and use of the ClinGen Resource is essential to ensure broad community uptake. We report on experiences and sustained use of ClinGen tools through engaging international genetics groups based in India, Africa and Singapore in variant classification training workshops using the ClinGen Variant Curation Interface (VCI). Methods: We developed pre and post workshop questionnaires and analyzed ClinGen tool use following the workshops. We evaluated organizational aspects and costs of creating a dedicated ClinGen VCI instance for each workshop. Results: The workshops yielded >200 participants, with local scientists as essential participants. While ~55% of participants were unfamiliar with variant classification, we found ~79% were likely to use the VCI after the workshop. Further, we identified about ~10% of workshop participants created permanent accounts. We estimate costs at ~$3 per VCI instance. Discussion: Our efforts highlight the yield of international workshops to sustained use of ClinGen's curation tools, and identify areas for future consideration such as creating user-groups by experience level, and the importance of local scientist engagement in workshop deployment and organizational aspects.
