Relevance of COLO829 tumour-only, indels (Krishnamachari et al. 2026) to "Select a tumour DNA somatic variant-calling workflow"
- Use case
- Select a tumour DNA somatic variant-calling workflow
- Assessed by
- COLO829 tumour-only, indels, AUPRC (Krishnamachari et al. 2026 Supplementary Table 1)
- Relevance
- Proxy evidence
- Endpoint
- AUPRC of tumour-only callers (VarNet-T, five DeepSom models, DeepSomatic, Mutect2, ClairS-TO): COLO829 tumour-only, indels
Proxy, not direct: per-caller AUPRC on real tumour and cell-line WGS with tumour-normal-derived truth sets is close to the use case's endpoint, but the callers used tumour reads only, whereas this use case's inputs include a matched normal and its exclusions list tumour-only calling; precision, recall and F1 are not extracted. Linked as the closest evidence for users without a matched normal.

- endpoint
- AUPRC of tumour-only callers (VarNet-T, five DeepSom models, DeepSomatic, Mutect2, ClairS-TO): COLO829 tumour-only, indels
- rationale
- Proxy, not direct: per-caller AUPRC on real tumour and cell-line WGS with tumour-normal-derived truth sets is close to the use case's endpoint, but the callers used tumour reads only, whereas this use case's inputs include a matched normal and its exclusions list tumour-only calling; precision, recall and F1 are not extracted. Linked as the closest evidence for users without a matched normal.
- constraints
- Inspect every linked evaluation's source locator before citing a result.; Do not combine this mapping's evaluations with any other protocol's results; truth sets, specimens, sequencing and caller versions differ between sources.
- limitations
- Developer paper: the authors developed VarNet-T (and earlier VarNet); its rows are author_reported. Comparators were run by the authors.; Tumour-only calling: the matched normal was used only to build the truth sets, not by the callers.; Only AUPRC is extracted; the threshold-optimised best F1 values are shown in figures only.; No interval estimates.; DeepSom's developers describe it as a caller of somatic SNVs (github.com/sergeyvilov/DeepSom repository description, checked 2026-10-11; not a pinned source); this source prints indel AUPRC for its models without explanation.; COLO829 truth is the TGen reference set and the reads are EGA EGAD00001002142; Chen et al. 2025 used the NYGC truth set and other COLO829 sequencing, so COLO829 values from the two papers are not comparable (ClairS-TO Illumina SSRS v0.4.0 SNV AUPRC 0.6500 there, 0.270 here).
