Symposium 2024’s Defining Themes
Presentations delivered by researchers from across the globe highlighted the following themes:
- OGM has moved beyond concordance studies as data sets expand, research reveals new, actionable biomarkers, and user groups form to drive standardization and implementation of the workflow.
- Insights that OGM is providing in hematological malignancy research are relevant in the context of applications to potential therapeutic development and maybe even one day patient management.
- OGM is helping to unravel persistent, complex mysteries in genetic disease that impact people, even in more common disorders like Down syndrome and Marfan syndrome.
- OGM has the potential to meet the key requirements of the cell and gene therapy community.
- OGM can serve as an alternative to, and an important bridge between, cytogenetics and molecular pathology by elevating something that is digital and molecular and complementing next-generation sequencing (NGS) which is an essential component of molecular pathology today.
“We were impressed by the engagement at our 2024 Symposium and are excited by the accomplishments of the global researchers who presented their OGM data during sessions and in scientific posters,” commented Alka Chaubey, PhD, FACMG, chief medical officer at Bionano. “OGM’s ability to identify pathogenic variants missed by many legacy techniques was highlighted in multiple presentations, including a presentation from day three, covering a research study that used OGM to successfully detect a repeat expansion missed by conventional cytogenetic methods over 15 years of analysis. Presenters also showcased OGM’s expansion into new application areas, where it has potential to outperform classical techniques, complement sequencing-based methods, and broaden researchers’ understanding of genomic landscapes.”
Research shared over the four-day virtual event expanded on key findings in several applications of OGM:
Day 1: New Standards in Hematologic Malignancies
- OGM can provide researchers with a simple, easy to implement workflow:
Tiffany Cloustonfrom Saint John Regional Hospitalhighlighted increasing demand for cytogenetics combined with limited staffing and training resources as a driver for her lab’s adoption of OGM, with sample preparation kits that are easy to use, and a sample-to-answer workflow that delivers whole genome structural variant (SV) analysis at high resolution, improving turnaround time.
- OGM can perform comparably to classical cytogenetics and can enable detection of additional pathogenic variants: Dr.
Guilin Tangfrom the University of Texas MD Anderson Cancer Centerdescribed results from a study on 28 T-lymphoblastic leukemia (T-ALL) samples that showed that OGM detected SVs in 100% of samples, even those with normal karyotype, and revealed additional, clinically relevant information in 56% of samples.
- International consortia have formed all over the world and they are establishing guidelines for standardized implementation of OGM and reporting of OGM data: Agnes Daudignon from
Lille Hospitaland Dr. Adam Smithfrom University of Torontodescribed two different consortia, a French group of OGM users called FrOGG, and the International Consortium for Hematologic Malignancies, which have formed to help members validate, implement and standardize OGM, fueling its expansion into new labs.
Day 2: New Frontiers in Oncology
- OGM has the potential to impact therapy selection and cancer risk assessment and to expand the understanding of heme malignancy applications compared to sequencing and classical cytogenetic methods: Dr.
Isabelle Raymond-Bouchardfrom Maisonneuve-Rosemont Hospitalpresented results from a study that used OGM to analyze 50 multiple myeloma (MM) samples, showing that OGM was highly concordant with classical cytogenetic methods and identified variants that led to a 30% increase in prognostic information, which may result in improved therapy selection. Dr. Scott Ryallfrom Brighamand Women’s Hospital also highlighted OGM’s impact on MM research, with findings that showed the workflow’s ability to detect clinically relevant SVs and to expand the understanding of the structural landscape of myeloma.
- OGM can identify clinically relevant SVs missed by traditional methods: A study presented by Dr.
Miriam Bornhorstfrom Lurie Children’s Hospital of Chicagoshowed that OGM was able to detect 20% more pathogenic variants in 100 pediatric brain tumor samples than classical cytogenetic methods.
- OGM can characterize and stratify Homologous Recombination Deficiency (HRD) in breast tumor samples: In a research study on Triple-Negative Breast Cancer (TNBC) presented by Dr.
Marc-Henri Sternfrom Institute Curie, OGM was able to clearly differentiate between homologous recombination proficient (HRP) and deficient (HRD) breast cancer cells, which could potentially help patients get access to life saving PARP inhibitors.
- High performance and utility make OGM a potential key assay for cancer research: Presenters shared data that underscored OGM’s high sensitivity, specificity, and fast turnaround time when compared to classical techniques including karyotyping (KT) and fluorescence in situ hybridization (FISH), which have been the standard for cytogenetic analysis of cancer samples for decades.
Day 3: Advances in Constitutional Applications
- OGM detected significant SVs missed by NGS, long read sequencing (LRS) and classical cytogenetic methods: Presentations delivered by Dr.
Nikhil Sahajpalfrom Greenwood Genetic Center, Dr. Laila El Khattabifrom AP-HP Sorbonne, and Dr. Maria Clara Bonaglia from Scientific Institute E. Medea included findings from OGM that were missed by multiple other methods and that proved important in research connected to unraveling longstanding mysteries in genetic disease.
- OGM can be highly concordant with traditional methods and accomplish, in a single assay, what took multiple assays in 60% of samples or more: In pre- and postnatal constitutional genetic disorder studies presented by Dr.
Roger Stevensonfrom Greenwood Genetic Center, OGM was shown to be a complete replacement for multiple techniques used in classical cytogenetics.
- Combination of OGM and NGS can improve upon and potentially replace traditional workflows: Across the presentations in day 3, the combination of OGM and NGS was shown to be highly complementary and that it may enable comprehensive genomic variation analysis in constitutional genetic diseases.
Day 4: OGM in Cell and Gene Therapy
- OGM is the only genome-wide tool used by the
National Institute of Standards and Technology(NIST) genome editing consortium: In the search for potentially deleterious effects of gene editing, OGM is the only genome-wide tool that meets the NIST genome editing consortium requirements for cost, accuracy, performance and speed. All other technologies that are part of the NIST consortium are targeted assays.
- OGM can offer high resolution and sensitivity compared to classical cytogenetic methods: OGM was reported to reliably detect on-target effects of CRISPR/Cas9 gene editing at variant allele frequency (VAF) as low as 1%, potentially providing an advantage over other techniques in quality control of pluripotent stem cells and evaluation of the integrity of laboratory cell lines.
- OGM can outperform classical cytogenetic methods to screen cell lines more easily for genomic instability and off-target events:
Owen Pearcefrom eGenesis shared data that highlighted how OGM can offer improvements in quality control compared to methods like KT, which will be crucial to cell and gene therapy applications with increasing pressure from the FDA.
“Symposium 2024 underscored OGM’s utility and demonstrated that the workflow has expanded beyond concordance studies. The event presentations provided data that showed OGM’s expansion into new applications, and its ability to uncover new actionable biomarkers. We were pleased to see researchers share findings that showed that OGM has the potential to impact genome research in a meaningful way,” commented Erik Holmlin, PhD, president and chief executive officer at Bionano. “I would encourage anyone who was unable to attend live to login, view these presentations and see how bright the future of cytogenetics is with OGM.”
