Overview

Genomic evaluation demonstrates comprehensive profiling of structural and copy number variants in multiple myeloma, highlighting the clinical utility of optical genome mapping for risk assessment.

Key Points

  • To evaluate optical genome mapping as a comprehensive strategy for identifying genome-wide structural variants, copy number alterations, and complex rearrangements in multiple myeloma.
  • Assessed optical genome mapping frameworks for detecting primary disease initiation drivers, such as hyperdiploidy and IGH fusions.
  • Evaluated platform utility for capturing secondary progression abnormalities, including MYC rearrangements, 1q gains, del(17p), and chromoanagenesis.
  • High-risk cytogenetic features, including del(17p), t(4;14), and t(14;16), were comprehensively profiled alongside emerging prognostic drivers such as MYC rearrangements and catastrophic chromoanagenesis.
  • Genome-wide variant detection enabled actionable identification of therapeutic targets, such as predicting responsiveness to BCL2 inhibition via t(11;14) translocations.
