Optical Genome Mapping

Optical Genome Mapping Background objectives: optical genome mapping (ogm) has recently emerged as a new technology in the clinical cytogenomics laboratories. this methodology has the ability to detect balanced and unbalanced structural rearrangements using ultra high molecular weight dna. Ogm is a workflow that combines technologies to reveal structural variation in the genome. it uses uhmw dna, fluorescent labels, nanochannel arrays, and software solutions to observe svs directly, not infer them from short read ngs.

What Is Optical Genome Mapping Optical genome mapping is a transformative technology that is based on dna labeling rather than sequencing. it can produce nearly error free assemblies from isolated linearized dna fragments (∼100 kb) to capture disease relevant svs and repeat architecture across the human genome. Optical genome mapping (ogm) is a novel cytogenomic method that identifies structural variants (svs) in the genome with high resolution. this study validates ogm’s concordance with legacy methods and shows its clinical utility for diagnosis of genetic disorders. Ogm relies on a specifically designed extraction protocol facilitating the isolation of ultra high molecular weight (uhmw) dna. this protocol utilizes a paramagnetic disk purposed with trapping dna for wash steps thereby reducing sheering forces present in standard column based extraction methods. Here we review some recent advances in optical genome mapping, including a brief introduction of optical mapping and its applications in dna profiling, clinical dna sensing, and genome.

This collection focuses on the application of optical genome mapping (ogm) technology in the clinical diagnosis of genetic diseases. Optical genome mapping detects balanced and unbalanced chromosomal scale variation, submicroscopic copy number alterations, and repeat expansions in a single assay. optical maps provide de novo human genome assemblies with accurate specificity and depth of coverage. Optical genome mapping (ogm) description: a proportion of genomic diagnoses is attributable to structural variation (sv). optical genome mapping (ogm) can detect genome wide svs at high resolution by labeling and mapping ultra long dna molecules (>150kb) in nanochannel arrays. Here we review some recent advances in optical genome mapping, including a brief introduction of optical mapping and its applications in dna profiling, clinical dna sensing, and genome sequencing.
