Bionano Announces Publication Showing that OGM Identifies Genetic Aberrations in Sarcoma Samples that May Lead to Improved Diagnosis but were Missed by Classical Cytogenetics

SAN DIEGO, April 03, 2024 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (Nasdaq: BNGO), today announced the publication of a peer-reviewed study that compared optical genome mapping (OGM) to classical cytogenetic techniques used for analysis of solid tumor cancer samples consisting of soft tissue and bone sarcomas, including fluorescence in situ hybridization (FISH) and karyotyping (KT). OGM demonstrated high levels of concordance with FISH and KT but was also shown to exclusively detect alterations in known oncogenes and tumor suppressor genes and to identify additional pathogenic aberrations, including chromothripsis and chromoplexy, that were not detected by multiple other cytogenetic methods.

Sarcomas represent over 100 histological subtypes and are highly heterogenous in their genetic landscape and prognosis. Accurate diagnosis of these tumors is dependent on the identification of underlying genetic aberrations, which can include large, and often complex, structural variants (SVs) or copy number variants (CNVs) involving oncogenes or tumor suppressor genes. The detection of SVs and CNVs remains challenging and typically requires multiple traditional cytogenetic techniques. In this study, researchers demonstrated OGM’s ability to detect aberrations as small as 500 bp, which is approximately 10,000-fold higher resolution than that of KT. As shown in this study, OGM can provide better characterization of the genomic complexity of sarcoma samples when compared to traditional cytogenetic techniques, due to the workflow’s high resolution and ​comprehensive, genome-wide analysis.

Key findings:

• OGM was concordant with traditional methods for the detection of pathogenic variants in 32 out of 35 cases (91%)
• OGM detected loss of CDKN2A/B in 9 out of 38 cases (24%), all missed by classical methods, which is associated with poor prognosis​ in soft tissue sarcomas
• OGM uniquely detected chromothripsis in 9 out of 35 cases (26%)
• In 5 out of 25 cases (20%) with diagnostic fusions, OGM showed that chains of rearrangements generated the fusions, three of which involved chromoplexy

“Characterization of sarcoma is enormously challenging and requires several different techniques, which often yield equivocal results that don’t explain the underlying disorder. We are pleased to see results from this study on the use of OGM to investigate sarcomas, which provided the study authors with insights into the genomic complexity underlying various aberrations, highlighting the high sensitivity and robustness of our workflow and enhancing our understanding of tumor biology.​ We believe this study is an important advancement for OGM and for the cancer research community as it now illustrates the utility of OGM not only in cancer, but in an important solid tumor,” commented Erik Holmlin, PhD, president and chief executive officer of Bionano.
