  1. A Unified Clinical Genomics Database NHGRI - U41 Genomic Resource Grant www.iccg.org

  2. Variant Analysis for General Genome Report 3-5 million variants • Genes ~20,000 Coding/Splice Variants • <1% • Published as • Disease-Causing • Pharmacogenetics 5-10 Variants Rare CDS/Splice Variants 20-40 “Pathogenic” Variants • LOF in Disease • Associated Genes 30-50 Variants • Review evidence for variant pathogenicity • Review evidence for gene-disease association and LOF role

  3. Classification of Reported Pathogenic Variantsfound in Human Genomes Likely Path – 1% Pathogenic – 2% Benign 18% Uncertain significance – 52% Likely Benign 26%

  4. U41 Genomic Resource Grant: • A Unified Clinical Genomics Database To raise the quality of patient care by: • Standardizing the annotation and interpretation of genomic variants • Sharing variant and case level data through a centralized database for clinical and research use • Implementing an evidence-based expert consensus process for curating genes and variant interpretations

  5. Supporting data collection, submission and curation Work with NCBI to design ClinVar to meet the needs of the community Develop data dictionary, ontologies, and work with standards bodies Define data submission and access policies for variant and case-level data including genotypes and phenotypes Work with labs to solicit and support data submission Evidence-based curation of structural variants - (Riggs et al. 2012 ) Evidence-based curation of sequence variants (ACMG Committee work in progress) Develop a gene-centric resource to define the medical exome and provide tools to support use in genomic medicine Work with vendors to improve reagents for genomic analysis (CMA, WES, WGS)

  8. Documenting arguments will improve the • evidence-based assessment of variants

  9. U41/ClinVar pilot project Comparison of three laboratories classifications for variants in 12 RASopathy genes: BRAF, CBL, HRAS, KRAS, MAP2K1, MAP2K2, NRAS, PTPN11, RAF1, SHOC2, SOS1, SPRED1 20% discrepant 53 discrepancies: 60% differ based upon likelihood (Benign vs LB, P vs LP) 34% differed VUS vs Likely Pathogenic/Likely Benign 6% differed VUS vs Pathogenic

  10. Lab Classification Differences 84% differences were Lab A reporting a more aggressive assertion (Pathogenic/Benign) than Lab B/C (LP, LB, VUS) 16% of differences were Labs B/C reporting a more aggressive assertion than Lab A

  11. ACMG Lab QA Committeeon theInterpretation of Sequence Variants ACMG Sue Richards (chair), Heidi Rehm (co-chair) Sherri Bale, David Bick, Soma Das, Wayne Grody, Madhuri Hegde, Elaine Spector AMP Julie Gastier-Foster, Elaine Lyon CAP Nazneen Aziz, Karl Voelkerding

  12. 5 Categories: Pathogenic Likely Pathogenic Uncertain significance Likely benign Benign Pathogenic = 1 stand-alone OR 2 strong OR 1 strong + ≥3 supporting Likely Pathogenic = 1 strong + 2 supporting OR ≥4 supporting Benign = 1 stand-alone OR 2 strong OR 1 strong + ≥3 supporting Likely benign = 1 strong + 2 supporting OR ≥4 supporting

  13.  *Variants should be classified as Uncertain Significance if other criteria are unmet

  14. QC and Expert Concensus Guideline Practice guidelines Expert Curation Evidence-based review ClinVar Multi-Source Curation Inter-laboratory Single-Source Curation Intra-laboratory Uncurated Large variant datasets dbSNP/dbVar

  15. Curation - ClinVar

  16. Analysis of LOF Variants - single genome 82 LOF variants below 5% MAF from one case Common 33 8 Reported Rare LOFs Novel/Rare - 41 Pathogenic - 2 (Both AR 1 novel 1 known) VUS – 1 (novel) Update database Not Mendelian 14 Excluded 46 False Positives 13 LOF not a disease Mechanism - 2

  17. Gene-centric resource • Define genes with medical relevance • Technical challenges • High GC • Pseudogenes/homologies • Repeat expansions • Common sites of structural variation • Variant types (denote common vs rare types) • Sequence variants (substitutions, small indels) • Loss-of-function vs. Gain-of-function • CNV – haploinsufficientvs. triplosensitive • Other structural changes (translocations, inversions, etc) • Imprinted loci • Repeat expansions • Medically relevant transcripts • Gene regions of pathogenic relevance • Patterns of inheritance (dominant, recessive, X-linked, mitochondrial, de novo, etc) • Phenotypes and evidence base for phenotype associations • Available approaches to define variant pathogenicity (assays, tools, etc) • Clinical utility measures • Clinical decision support opportunities Initiated through collaboration amongst CHOP, Emory, and Harvard/Partners and Structural Variant workgroup

  18. U41 - Working with Existing Efforts • NCBI (ClinVar, dbSNP, dbVar, dbGaP, GTR) and EBI • NHGRI (CRVR, eMERGE, CSER, ROR), IRDiRC • Regulatory and Standards: ACMG, CAP, CDC, FDA, ASHG, AMP, CMGS, Global Alliance • Locus Specific Databases (LSDBs – LOVD and non-LOVD) • InSiGHT, PharmGKB, MSeqDB, CFTR2, ENIGMA, etc • Human Variome Projectand HGVS • PhenoDB (Ada Hamosh) and Human Phenotype Ontology (Peter Robinson) • OMIM (Ada Hamosh) and GeneReviews (Bonnie Pagon) • Patient Advocacy Groups (Genetic Alliance, Patient CrossRoads, UNIQUE, Disease Specific Groups) • Industry partners (reagents, instruments, software, etc)
