CGC 2020 Webinars
Welcome to the webinar series sponsored by the Cancer Genomics Consortium and the University of Wisconsin Collaborative Genomics Conference.
These lecture series focus on topics of high interest for CGC members and attendees of the UW Collaborative Genomic Conference, including implementation of new technologies in clinical genetic/genomic testing, standards and resources for interpretation of sequence and copy number variants, germline predisposition to cancer and novel approaches for detection of structural variants in constitutional and cancer samples.
Circulating tumor DNA testing in oncology: established and emerging approaches, clinical utility and applications
Trevor Pugh, PhD, FACMG
Princess Margaret Cancer Centre, Ontario Institute for Cancer Research, University of Toronto
Clinical use of circulating tumor DNA (ctDNA) testing is rapidly increasing, but this type of analysis remains technically challenging, and its clinical utility and optimal utilization in clinical management of cancer patients are still being investigated. In this webinar, Dr. Pugh will review technical aspects of ctDNA testing (including specimen types and collection, transport, DNA isolation, assay design and performance characteristics); different types of biomarkers that are being monitored by ctDNA approaches (sequence variants, copy number changes, methylation profiles and ctDNA fragmentation patterns); evidence of clinical validity and clinical utility; and applications of ctDNA testing in genomic characterization of tumors at diagnosis, in non-invasive monitoring of advanced cancers, in detection of residual disease and relapse, and even in screening for cancer in asymptomatic individuals.
Resources for Interpreting Cancer Genomes: From Knowledgebases to Gene Lists
Beth Pitel, M.S., CG (ASCP)
Mayo Clinic
Interpreting cancer genomes is a challenging task requiring the use of references from the literature and other helpful resources and tools. In this webinar we will learn about several available databases and knowledge bases that can aid in cancer variant interpretation. Beth Pitel will illustrate how these resources helped the Genomics of Oncology Annotation Team (GOAT) at Mayo Clinic create disease-specific gene lists used as resources for the interpretation of chromosomal microarrays. Additionally, the CGC and the Mayo GOAT are collaborating in an effort to fine-tune a process for curating disease-specific gene lists.
Copy Number Abnormality Detection from Whole Genome Sequencing Data
Alka Chaubey, PhD, FACMG
Head of Cytogenomics, Perkin Elmer Genomics
Dr. Alka Chaubey will discuss the utilization of low pass genome sequencing as a new diagnostic approach for CNV detection across the entire genome. Dr. Chaubey will provide evidence from internal validation studies for CNGnome® test, which by utilizing 5x genome sequencing delivers an increased level of CNV detection when compared to traditional methods. Multiple case examples will be discussed in the webinar to demonstrate the clinical capabilities of CNGnome®. Several examples of whole genome sequencing (>30X depth) with pathogenic sequencing and copy number variants will also be discussed.
Interpretation of Copy Number Abnormalities (CNAs) and CN-LOH in Cancer using the ACMG / CGC Standards: Working through Complex Cases
This webinar provides practical guidance how to streamline interpretation of CNAs and CN-LOH in neoplasia using the current ACMG/CGC standards. Easy steps to generate clear, accurate and well organized reports will be illustrated. Using case examples, the speakers will explain challenging concepts including interpretation of genomic complexity, adjustment of ploidy, estimation of the percentage of involved cells and reporting of abnormalities suspected to be germline.

Optical Mapping and its Role as a Cytogenomics Tool in Cancer
Dr. Brynn Levy, MSc (Med), PhD, FACMG
Columbia University Medical Center,
New York Presbyterian Hospital
Dr. Levy will describe the principles of optical mapping, illustrate the capacity of this technology to detect balanced structural rearrangements in different sample types, and compare its performance with classic cytogenetic approaches including karyotype analysis and fluorescence in situ hybridization testing.
Application of Optical Mapping for Comprehensive Assessment of Structural Rearrangements in Hematological Malignancies
Dr. Rashmi Kanagal-Shamanna, MD
The University of Texas MD Anderson Cancer Center
Dr. Kanagal-Shamanna will discuss the application of optical mapping in comprehensive genomic characterization of hematological malignancies and highlight the clinical utility of this technique in management of including myelodysplastic syndromes.
