| Abstract Title | Fusion.AR-DB: A Collaborative Knowledgebase of Actionable Gene Fusions in Pediatric Cancers Leveraging Large-Scale RNA-Seq Data |
| Abstract Summary | Gene fusions are powerful oncogenic drivers and biomarkers in pediatric and AYA (adolescent and young adult) cancers, yet their clinical utility remains underexploited due to fragmented datasets, limited detection approaches, and the lack of centralized, clinically meaningful resources. We propose Fusion.AR-DB, the first open-access, comprehensive knowledge base of gene fusions in pediatric and AYA cancers. The objective is to systematically detect, annotate, and organize gene fusions across publicly available RNA-Seq datasets, including NIH Kids First, TARGET, CCDI, and others. Fusion.AR-DB will catalog all detected fusions, not only known or actionable ones, and associate them with clinical data like tumor types, molecular subtypes, and expression profiles. Therapeutically actionable events will be linked to FDA/EMA-approved drugs and clinical trials. Each fusion will be annotated with functional and structural insights, including domain-level information, expression impact, and structure of the resulting chimeric proteins, enabling downstream modeling and docking. Built with a validated, high-performance pipeline optimized for low-input pediatric samples, the platform integrates tools such as STAR and Arriba. All analyses will be run in a high-performance computing environment. The results will be delivered via a user-friendly, interactive interface, allowing users to explore fusion prevalence, co-occurrence, functional relevance, and therapeutic potential. Preliminary analyses reveal: - Undetected kinase fusions in high-risk pediatric cancers. - Novel recurrent fusion actionable events. - Actionable fusions in ~7% of FISH-negative tumors. Impact: Fusion.AR-DB increases therapeutic eligibility up to 3-fold in pilot cohorts, reduces diagnostic costs by over $1.2M/year per institution, and directly supports NIH goals by transforming RNA-Seq data into clinically actionable, personalized insights.
