Clinical NGS Assays

Molecular diagnostics, particularly next-generation sequencing (NGS), have become an integral component of disease diagnosis. Still, there is work to be done to establish these tools as the standard of care. The Third Annual Clinical NGS Assays event will address NGS assay validation, establishing NGS standards, and determining clinical relevance. The pros and cons of various techniques such as gene panels, whole exome, and whole genome sequencing will also be debated with regards to depth of coverage, clinical utility, and reimbursement. Overall, this event will address the needs of both researchers and clinicians while exploring strategies to increase collaboration for improved patient outcomes.

8:40 Best Practices for Using Genome in a Bottle Reference Materials to Benchmark Variant Calls

Justin_ZookJustin Zook, National Institute of Standards and Technology

NIST has hosted the Genome in a Bottle Consortium to develop well-characterized human genomes to enable benchmarking of variant calls. We also are working with the Global Alliance for Genomics and Health Benchmarking Team to develop tools to calculate standardized performance metrics when comparing variant calls to our benchmark samples. I will discuss our well-characterized genomes and how to use them to benchmark variant call accuracy, and important considerations for clinical laboratories.

9:10 NGS in Clinical Diagnosis: Aspects of Quality Management

Pinar Bayrak-Toydemir, M.D., Ph.D., FACMG, Associate Professor, Pathology, University of Utah; Medical Director, Molecular Genetics and Genomics, ARUP Laboratories

Next-generation sequencing (NGS) technologies continue to be improved in clinical laboratories, enabling rapid transformations in genomic medicine. NGS could be an extensive process both at the wet bench and bioinformatics levels. Quality assurance steps including how to detect sample switch, alignment and variant calling algorithms for in-dels, and necessity for Sanger sequencing confirmation will be discussed using interesting clinical cases.

9:40 Thorough Validation and Implementation of Preimplantation Genetic Screening for Aneuploidy by NGS

Rebekah_ZimmermanRebekah Zimmerman, Ph.D., Laboratory Director, Clinical Genetics, Foundation for Embryonic Competence

We have developed and validated a targeted NGS assay for whole chromosome aneuploidy that has comparable accuracy to qPCR, while improving cost and throughput limitations. Also of critical interest, we have explored limits of detection for mosaicism and segmental aneuploidy, which are two areas of major concern among the IVF community.

11:00 Are We There Yet? The Odyssey of Exome Analysis and Interpretation

Avni_SantaniAvni B. Santani, Ph.D., Director, Genomic Diagnostics, Pathology and Lab Medicine, The Children’s Hospital of Philadelphia

The comprehensive analysis of complex genomic data such as exome sequencing presents several challenges to a clinical laboratory. Factors including phenotyping, use of public and internal databases and balancing sensitivity with a rapid return of results are critical. Using several cases as examples, the critical areas during the exome interpretation process will be highlighted.

11:30 Challenges in Exome Interpretation: Intronic Variants

Rong_MaoRong Mao, M.D., Associate Professor, Pathology, University of Utah; Medical Director, Molecular Genetics and Genomics, ARUP Laboratories

Exome sequencing, the targeted sequencing of the subset of the human genome that is protein coding, is a powerful and cost-effective new tool for dissecting the genetic basis of diseases and provide a diagnostic odyssey for undiagnostic rare and complex conditions. Interpretations of variants detected by exome sequencing, determination of the pathogenicity and clinical significant of the variants are big challenge. Hereby I present the intonic variants detection and interpretation by exome sequencing

12:00 pm Exome Sequencing: Case Studies of Diagnostic and Ethical Challenges

Lora_BeanLora J. H. Bean, Ph.D., Assistant Professor, Human Genetics, Emory University

Exome sequencing in the age of variant databases and data sharing is a powerful tool in genetic diagnostics; however, analysis of variants across the entire exome presents interpretative and ethical challenges. Cases will be presented demonstrating the challenge of diagnosing a newly described syndrome and making a dual diagnosis, as well as cases exemplifying the challenges of technical limitations, specifically the inability to detect deletions or sequence genes with pseudogenes.

2:05 Assessing the Feasibility of Establishing Performance Standards for Next Generation Sequencing Based Genetic Testing

Karl_VoelkerdingKarl V. Voelkerding, M.D., Professor, Pathology, University of Utah; Medical Director for Genomics and Bioinformatics, ARUP Laboratories

In this presentation, the concepts of validation and establishment of performance characteristics for NGS tests will be discussed in relation to CAP accreditation requirements. Results from the CAP methods based proficiency testing program for detection of germline variants launched in 2015 will be presented in the context of a discussion of the feasibility of establishing performance standards for germline NGS testing.

2:35 Clinical Cancer Genomics-Driving Precision Medicine

Shashi Kulkarni, MS, Ph.D., Vice Chairman, Research, Molecular and Human Genetics, Baylor College of Medicine Houston Texas; Chief Scientific Officer, Baylor Miraca Genetics Laboratory

Next-generation DNA sequencing technology is revolutionizing clinical cancer genomic diagnostics by enabling precision cancer medicine by directing molecularly targeted therapies. Adoption of NGS brings unprecedented challenges in incorporating this technology in the clinical setting. This presentation will provide a comprehensive overview on the key considerations for implementation of clinical next-generation sequencing including resource allocation, assay development, compliance, bioinformatics, data management, analysis and interpretation of data in a CAP/CLIA environment.

3:05 NGS Harmonization Manifold: From Data to Ontologies, from Computations to Knowledge

Vahan_SimonyanVahan Simonyan, Ph.D., Lead Scientist, Director, Bioinformatics; Principal Investigator, HIVE, Food and Drug Administration (FDA)

Multiple aspects of data and computation standardizations will be discussed from research and regulatory perspectives. Brief description of FDA’s NGS harmonization efforts in the form of High-performance Integrated Virtual Environment (HIVE) will be outlined and biocompute object database for harmonized computational protocols will be described.

3:35 An NGS Inter-Laboratory Study to Assess Performance and QC

Andrea Ferreira-Gonzalez, Ph.D., Chair, Molecular Diagnostics Division, Pathology, Virginia Commonwealth University Medical School

Trevor Brown, MSc, Vice President, Precision Medicine, SeraCare Life Sciences

NGS assays that accurately detect somatic mutations in tumor tissue are crucial to precision medicine. Laboratory-developed test procedures need to be accurate, precise, clinically relevant, and monitored for continued quality performance. However, the technical performance between laboratories has been difficult to assess because there are no widely accepted standards. This presentation describes an inter-laboratory study using Seraseq™ biosynthetic reference materials to assess different platforms, assays, and pipelines for routine QC use.
