ClinGen The Clinical Genome Resource Sharing Clinical Genetic Knowledge HL7 Clinical Genomics Weekly Call Dec 12, 2017 Larry Babb, ClinGen Data Model WG co-chair [email protected] Disclosure Larry Babb is employed by MitoGen/GeneInsight, a Sunquest Information Systems company. Sunquest is a commercial laboratory software vendor. Todays Objective Stimulate discussion on the need for sharing clinical grade genetic knowledge that is not directly associated to a patient finding. What type of data are we talking about? Is this within the scope of HL7? Might it impact the current HL7 CG models? ng i r

Data Sharing is Critical to Precision Medicine (not just patient data!) Updates to clinical-grade knowledge repositories and sources inform physician treatment plans. Providing standard, accurate and precise association of knowledge and genetic results is essential to applying that knowledge in clinical care. Both lab and physician systems need the ability to provide access to data in a timely and context appropriate manner Clinicians and researchers alike need to be able to safely and effectively share new findings in order to speed discovery which benefits all. What kinds of data are we talking about? Standardized Variant Representation Sequence Variants allele, haplotype, genotype (precise DNA and AA variants) Structural Variants CNVs, gene fusions, translocations, inversions, others Standardized Gene and Variant Interpretation
