Structural Variants in Hematological Malignancies

Chromosomal aberrations are a major contributing factor to the pathology of hematological malignancies. The first step to understanding the etiology and progression of these malignancies is by detecting and identifying structural and copy-number variants. With this knowledge results may:

  • Increase the number of informed samples
  • Provide a faster time to pathogenic genomic findings
  • Increase the accuracy of sample risk stratifications

The challenge has been that with classical cytogenetics methods researchers cannot detect or resolve many of the relevant chromosomal abnormalities.
Finally, Optical Genome Mapping reveals them.

Optical Genome Mapping (OGM)

Optical Genome Mapping reveals what you need to see

OGM captures all classes of structural and copy-number variants in a single assay—detection that usually takes multiple cytogenetic techniques to capture. Now labs can generate more meaningful information in a simpler and more efficient way.

The OGM genome-wide platform brings unbiased, digital precision to solve unresolved cases across hematological malignancies.

Spans the full genome

Unbiased workflow

Combines high-resolution with digital analysis

Can reliably resolve all classes of structural and copy-number variants in a single workflow

Detects more pathogenic chromosomal abnormalities

Learn about the OGM advantage in hematological malignancies

“There is this wide region of the genome that no one has even looked at or interrogated. And the things you can do using OGM technology…the discoveries, the identification of biomarkers, prognostication, improving therapy, identifying targets, it’s endless. The potential is endless, and I’m super excited to work with this in the future.”

OGM revolutionizes the way cytogenetics contributes to cancer research

OGM is moving the field of hematological malignancy research forward in two ways:

  1. It provides a single assay to detect the chromosomal aberrations of clinical and biological significance that traditional techniques may detect after two, and often more, assays.
  2. It reveals more with a higher resolution that can resolve complex structures that are otherwise cryptic or completely missed by classical techniques.

High concordance with classical cytogenomic methods

Better characterization and resolution of structural variants

Reveals more pathogenic variants

OGM captures all classes of structural and copy-number variants seen with karyotyping, FISH and chromosomal microarrays—in a single method

“30% of previously unsolved cases for B-ALL, which previously underwent karyotype + FISH +microarray + NGS, were solved using OGM.”
