- OGM detected chromosomal aberrations missed by karyotyping and FISH in 35 cases
- OGM Sensitivity: 98.7%
- OGM Specificity: 100%
- Positive Predictive Value: 100%
- Negative Predictive Value: 98%
- OGM Accuracy: 99.2%
- First-Pass Success Rate: 100%
- Limit of Detection (LOD) for aneuploidies, translocations, interstitial deletions and duplications at 400X: 5% variant allele fraction
This study, published by researchers from
Researchers used 69 unique samples comprised of 59 hematological neoplasms (CLL, AML, MDS, MM, lymphoma, PCM, CML, ET and others*) and 10 phenotypically normal and cytogenetically negative samples for controls. The 59 hematological neoplasms consisted of 43 simple and 16 complex cases, which included all classes of SVs.
Within the 59 heme samples, OGM showed a 98.7% sensitivity and 100% specificity for detecting SVs previously reported with karyotyping and fluorescence in situ hybridization (FISH). Additionally, 35 of 43 simple cases had at least one clinically reported aberration, and OGM detected all of the reported variants, found additional aberrations in 23 cases, and corrected putative false-positive results in two of the cases. In complex cases, OGM revealed the identity of 12 marker chromosomes and one ring chromosome and found additional SVs, including 145 translocations and 67 putative novel gene fusions.
To evaluate technical and analytical reproducibility, inter-run, intra-run and inter-instrument comparisons were performed on six samples in triplicates. OGM demonstrated 100% reproducibility and a LoD of 5% for aneuploidies, translocations, interstitial deletions and duplications at 400x coverage.
“Increasingly, the body of evidence available on the performance of OGM in hematological malignancies demonstrates high performance and utility, but this study put OGM’s performance to the test in a more routine, analytical environment,” said
