Bionano Genomics Announces the First Publication Using OGM to Analyze Impact of Chromothripsis and TP53 Abnormalities on Chronic Lymphocytic Leukemia (CLL) Patients with High Genomic Complexity
Bionano Genomics (NASDAQ: BNGO) announced the publication of a pioneering study utilizing optical genome mapping (OGM) to investigate the effects of chromothripsis (cth) and TP53 abnormalities in chronic lymphocytic leukemia (CLL) patients with high genomic complexity. The research analyzed 162 CLL patients, confirming OGM's capability to detect cth and its correlation with chromosomal microarray results. While cth was linked to shorter time to first treatment, only TP53 mutations significantly influenced prognosis, indicating that TP53 abnormalities may be the main contributor to adverse outcomes. The study highlights OGM's unique detection power.
- Publication of a study validating OGM's effectiveness in detecting chromothripsis and TP53 abnormalities.
- High concordance between OGM results and traditional chromosomal microarray data.
- OGM's potential to reveal complex genetic rearrangements in CLL patients.
- Chromothripsis was not associated with time to first treatment when considering TP53 status, undermining its perceived prognostic value.
SAN DIEGO, Aug. 25, 2022 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (Nasdaq: BNGO) today announced the publication of the first study to use optical genome mapping (OGM) to analyze the impact of chromothripsis (cth) and TP53 abnormalities on chronic lymphocytic leukemia (CLL) patients with high genomic complexity. Researchers aimed to determine whether poor prognostic outcomes observed in cases with cth might be related not only to the chromothriptic event itself but also to the presence of complex karyotypes or TP53 abnormalities.
The paper, published in Cancers journal, was conducted by a multi-center group of researchers from hospitals and academic labs across a number of European countries. The study compared the cytogenomic aberrations observed by genomic microarrays and chromosome banding analysis (CBA) to those observed using OGM. Researchers analyzed a cohort of 162 CLL patients with complex karyotypes, including a subset of 33 CLL patients with cth, to determine whether the presence of cth indicated poor survival outcomes.
In this study, researchers were able to show, for the first time, OGM’s ability to detect cth, and also showed that the OGM results were highly concordant with chromosomal microarray results. The study noted that detecting cth using some traditional cytogenetic approaches can be challenging and reported that OGM was able to reveal rearrangements associated with cth events, including intra-chromosomal and inter-chromosomal translocations. In addition, OGM was able to detect a case with a higher complexity profile, comprising chained translocations involving several chromosomes, which may be characteristic of another event known as chromoplexy.
Though cases with cth showed shorter time to first treatment (TTFT) than non-cth samples, when researchers stratified patients based on TP53 status, cth was no longer associated with TTFT. Only TP53 maintained its significance in the multivariate analysis for TTFT, including cth and genome complexity defined by genomic microarrays, leading the researchers to suggest that TP53 abnormalities, rather than cth itself, underlie the poor prognosis observed in this subset.
“We are excited to see the adoption of OGM in the hematologic community in Spain. This team of researchers have done outstanding work diving into some complex questions in cancer. The results of this study show that while chromothripsis plays a factor in the proliferation of structural variation, TP53 emerges as a critical biomarker with high prognostic value. We believe the study also shows that OGM was unique in its potential to reveal these critical events. The report shows that a few of the variants detected by CMA were not detected by OGM, which we believe reflects the performance of earlier versions of our analysis software and will help guide development of future versions. It is noteworthy that this publication documents OGM’s ability to analyze TP53 variants, because we are aware of new international classification subtypes that emphasize the importance of TP53 structural variants in conjunction with single nucleotide variants,” commented Erik Holmlin, PhD, president and chief executive officer of Bionano Genomics.
