Bionano Announces Peer-Reviewed Publication from its Clinical Study Designed to Support OGM as Part of Standard of Care (SOC) in Genetic Disease Testing
- Peer-reviewed publication from Broeckel, et al. describes the second phase of a multisite evaluation of optical genome mapping (OGM) in 627 samples (597 unique samples and 30 replicates)
- Overall, for the entire study, OGM data have been collected from 1,000 samples, including 404 samples from phase 1 of the study
- Concordance for pathogenic variants in all combined samples against standard of care (SOC) methods – 99.5% (995 out of 1,000 samples)
- When compared to the rate of finding pathogenic or likely pathogenic variants with SOC methods, OGM increased the rate by a factor of 6% to as much as 50% depending on the patient population
The sites conducting the study and their principal investigators are as follows:
- University of Rochester Medical Center (Dr. M.
Anwar Iqbal ) Medical College of Wisconsin (Dr. Ulrich Broeckel)- Columbia University Medical Center (Dr. Brynn Levy)
- Greenwood Genetic Center (Dr. Roger Stevenson)
Medical College of Georgia , Augusta University (Dr. Ravindra Kolhe)- Praxis Genomics (Dr. Peter
L. Nagy ) - University of Iowa Hospitals & Clinics (
Aaron Stence ) - H.
Lee Moffitt Cancer Center (Dr.Aaron Bossler )
Key Findings
The peer-reviewed publication describes OGM performance metrics compared to SOC methods for challenging samples from diagnosed and undiagnosed rare diseases. The key findings are:
- OGM concordance for pathogenic variants in all combined samples against SOC methods was 99.5% (995 out of 1,000 samples).
- OGM increased the rate of finding pathogenic or likely pathogenic (P/LP) variants over that of SOC by a factor of 6% to as much as 50% depending on the patient population as outlined below:
| Patient Population |
Number of Samples |
Number of Samples w P/LP findings by method | Improvement by OGM (%) |
||
| SOC | OGM | ||||
| Retrospectively collected samples from patients suspected of various genetic disorders | 405 | 70 (17.3%) | 91 (22.5%) | 30 | % |
| Retrospectively collected samples from patients suspected of ASD | 216 | 32 (14.8%) | 34 (15.7%) | 6 | % |
| Prospectively collected samples from patients suspected of a genetic disorder | 94 | 5 (5.3%) | 10 (10.6%) | 50 | % |
Key Takeaways
The study authors reported that results demonstrate the ability of an OGM workflow to detect all classes of structural variants (SVs) with higher resolution compared to current SOC methods, including aneuploidies, triploidy, translocations, inversions, insertions, microdeletions, microduplications, nucleotide repeat expansions or contractions, and absence of heterozygosity (AOH). In contrast to variants that are detected by microarray, which are limited to gains and losses, the variants reported by OGM include all classes of SVs, several of which reside in candidate genes associated with the phenotype. The authors concluded that OGM can offer a simple and streamlined workflow that can detect relevant genomic aberrations and mitigate the need for numerous testing platforms and time-consuming wet lab work, potentially improving lab performance by reducing the associated time and costs.
“Development and validation of OGM assays for postnatal analysis is an area where we believe our technology can have tremendous global impact. The performance we have seen matches our expectations. We are extremely happy with this publication demonstrating OGM’s performance across multiple sites and its potential ability to perform in a single assay what today requires multiple technologies,” commented Erik Holmlin, PhD, president and chief executive officer of Bionano.
“The process of establishing a trial program like this one is made possible by capable principal investigators and leading sites,” commented Alka Chaubey, PhD, FACMG, chief medical officer of Bionano. “We are pleased that these study authors concluded that OGM should be considered as a first-tier method of analysis for postnatal genetic disorders, and that their findings support the utility of a novel tool like OGM to help solve challenging cases in constitutional and rare diseases, including those involving pediatric intellectual disabilities and autism.”
