Working definition
Structural variants in this corpus are genomic alterations typically 50 bp or larger, including deletions, insertions, duplications, inversions, translocations, mobile element insertions, and repeat-mediated events.
What this corpus says
- Structural variation is the clearest and most consistent advantage zone for long-read WGS.
- Long reads especially improve discovery of insertions, inversions, repeat-associated events, and rearrangements that short reads undercount or mischaracterize.
- Population-scale long-read SV resources are becoming useful not only for discovery but also for patient-level filtering.
- The clinically important shift is not just more calls, but more sequence-resolved and structurally interpretable calls.
Supporting sources
Current takeaways
- Insertions are disproportionately missed by short-read workflows.
- Inversions and large complex events still often benefit from orthogonal or graph-aware approaches even within the long-read era.
- SV reference panels and atlases are becoming a realistic extension of long-read cohort studies.
Open questions
- Which SV classes now require full multi-platform support, and which are well covered by modern single-platform long-read workflows?
- How should SV resources be integrated into routine clinical prioritization pipelines?
