ChromBPNet trained on 17 hematopoietic cell types predicts that 5.6% of 242,307 variants accessible in at least one cell type alter chromatin accessibility, with effects structured by lineage.
- Why it matters: Most GWAS hits are noncoding, and their molecular mechanisms across differentiation hierarchies are unclear; sequence-to-function models could clarify where variants act.
- What they did: The study trained ChromBPNet to score 302,830 variants across 17 cell types, then compared predicted effects to hematopoietic lineage relationships and to GWAS fine-mapping and K562 CRISPRi validation.
- The result: Predicted effects shared less with increasing lineage distance while direction was preserved in 99.6% of parent-child comparisons; ChromBPNet and fine-mapping agreed but highlighted largely distinct variants, and accessibility gain showed limited association with target-gene validation in K562.
