A meta-analysis of 2,014 Ewing sarcoma cases and 10,525 controls identified 18 variants across 14 susceptibility loci, including 9 novel loci, with odds ratios ≥1.25.
- Why it matters: Ewing sarcoma lacks established environmental risk factors, so inherited susceptibility is a key gap for explaining disease etiology and mechanisms.
- What they did: They combined an international genome-wide association study with a case-parent trio study, then performed integrative analyses of the EwS loci and EWSR1::ETS knockdown in EwS cell lines.
- The result: The loci were enriched for enhancer-like GGAA microsatellites, showed evidence of EWSR1::FLI1 binding at most loci, and knockdown dysregulated genes tied to skeletal/muscle development, RNA processing, and chromatin regulation.
