Ogm testler

This LDT utilizes optical genome mapping OGMa technique that provides genome-wide assessment of all classes of SVs, including: aneuploidies, large and small copy number variants, balanced and unbalanced rearrangements including insertions, ogm testler, inversions, and translocations. This assay may be indicated for fetuses where a genetic anomaly is suspected, such as:. Bionano Laboratories offers clinical support to patients and providers through access to our genetic counselors who can discuss testing capabilities, strategy, informed consent, and ogm testler.

Structural genomic alterations can be visualized by several techniques, including chromosome analysis by light microscopy, chromosome microarray analysis CMA , and fluorescence in situ hybridization FISH. Optical genome mapping analysis is performed with high-molecular DNA average of fragment length: kilobase pairs labeled with a fluorescent dye. Up to , single DNA molecules are passed through nano channels and scanned with a laser. The data is mapped to a reference genome, allowing structural variants of the entire genome to be visualized. Diagnostic advantages of optical genome mapping. Exact breakpoint determination of unbalanced chromosomal alterations:. This makes it possible to investigate complex genomic structural changes in a single diagnostic approach.

This assay is indicated for individuals who are suspected of having a new diagnosis of a hematological malignancy and for individuals who have an existing diagnosis of a hematological malignancy, such as:. This LDT utilizes optical genome mapping OGM , a technique that provides genome-wide assessment of all classes of SVs, including: aneuploidies, large and small copy number variants, unbalanced rearrangements, insertions, inversions, and translocations. The OGM-Dx HemeOne reports from this LDT will include a whole genome analysis to assess for complex genomes as well as a targeted evaluation of actionable SVs that are recommended to be tested across multiple guidelines. Bionano Laboratories offers unlimited clinical support to patients and providers through access to our genetic counselors who can discuss testing capabilities, strategy, informed consent, and results. This technique is based on site-specific labeling of ultra-high molecular weight DNA followed by imaging of the DNA molecules during linearization within nanochannel arrays. This allows for the detection of structural variants at a very high resolution and sensitivity at genome-wide resolution. All classes of structural variants SVs are detected in a single assay, including copy number variants, balanced and unbalanced translocations, inversions, insertions, and aneuploidies. OGM data analysis is performed using a graphical user interface tool for variant visualization, interpretation, and curation. Both genome-wide and hematological malignancy subtype specific interpretation is performed, and SVs are classified according to standard medical guidelines by board certified laboratory directors. Optical genome mapping is a technique using a streamlined workflow capable of detecting all classes of structural variations in the human genome, including deletions, duplications, insertions, translocations, inversions, and repeat contractions and expansions. The DLS method, where fluorescent labels are attached to a 6 bp sequence motif, provides an average genome-wide resolution of approximately of 5 kbp. The labeled DNA is linearized in nanochannel arrays in the Saphyr instrument and imaged for the generation of digital barcodes for mapping the SVs in the human genome.

OGM-Dx HemeOne is a laboratory developed test for the detection of structural variants of diagnostic and prognostic value in individuals with a new diagnosis, or an existing diagnosis of a hematological malignancy.

This allows for the detection of structural variants at a very high resolution and sensitivity at genome-wide resolution.

The current standard-of-care cytogenetic techniques for the analysis of hematological malignancies include karyotyping, fluorescence in situ hybridization, and chromosomal microarray, which are labor intensive and time and cost prohibitive, and they often do not reveal the genetic complexity of the tumor, demonstrating the need for alternative technology for better characterization of these tumors. Herein, we report the results from our clinical validation study and demonstrate the utility of optical genome mapping OGM , evaluated using 92 sample runs including replicates that included 69 well-characterized unique samples 59 hematological neoplasms and 10 controls. OGM demonstrated robust technical, analytical performance, and interrun, intrarun, and interinstrument reproducibility. OGM identified several additional structural variations, revealing the genomic architecture in these neoplasms that provides an opportunity for better tumor classification, prognostication, risk stratification, and therapy selection. Overall, OGM has outperformed the standard-of-care tests in this study and demonstrated its potential as a first-tier cytogenomic test for hematologic malignancies. Published by Elsevier Inc.
