Near-complete, haplotype-resolved assemblies of an early-passage hypodiploid pancreatic cancer cell line recapitulate all 35 karyotyped chromosomes and reveal complex centromere and inversion rearrangements.
- Why it matters: Resolving somatic variants and methylation is difficult in repeats, reference gaps, and germline-variant–rich regions, limiting accurate tumor evolution and precision-medicine benchmarking.
- What they did: The study builds and curates tumor and matched-normal assemblies of the most recent common ancestor, then benchmarks somatic calls, adding >8,000 small variants (~40 kbp) and 149 SVs (939 kbp).
- The result: The benchmark includes 2,764 small variants and 126 SVs absent from GRCh38, plus 5,111 small variants whose representation changes via GRCh38 germline variants, enabling improved algorithms for repetitive cancer regions.
