Constellation technology utilizes a highly simplified NGS workflow that enables on-flow-cell library prep that completely eliminates standard library prep prior to sequencing. Standard cluster generation and SBS sequencing is combined with cluster proximity information in DRAGEN algorithms to unlock long-distance information. Early testing demonstrates enhanced mapping of challenging genomic regions, ultra-long phasing, and improved detection of large structural rearrangements.

Research on cancers such as acute myeloid leukemia, myelodysplastic syndrome, myeloma, and chronic lymphocytic leukemia has led to major improvements in personalized care. Traditional approaches to testing may include karyotype, FISH (fluorescence in situ hybridization), chromosomal microarray, and gene panels. Whole-genome sequencing can detect all the critical abnormalities and variant types relevant for these conditions with a single workflow.

With the DRAGEN v4.3 release, we introduce the second-generation multigenome mapper. This article discusses the evolution of its methodology using pangenome references and shows the significant accuracy improvement both in the All Benchmark Regions and Difficult-to-Map Regions of the genome, with the second-generation multigenome mapper and the most recent 128-samples pangenome reference.
