Briefings

This study introduces FusionRare, a unified framework integrating symbolic reasoning, deep learning, case retrieval, and LLM inference to diagnose rare diseases. Evaluated on 2,528 isolated clinical cases, the system achieved a macro-averaged Recall @1 of 51% for phenotype-only diagnosis and 79% for phenotype-genotype joint analysis. A randomized, crossover clinician-AI validation showed FusionRare elevates the true diagnostic rank in 45% of decisions and improves physician confidence in 62% of cases.

Key points

• FusionRare is a unified framework integrating symbolic reasoning, deep learning, case retrieval, and LLM inference to diagnose rare diseases.
• Evaluated on 2,528 isolated clinical cases, the system achieved a macro-averaged Recall @1 of 51% for phenotype-only diagnosis and 79% for phenotype-genotype joint analysis.

Context

Rare diseases affect an estimated 300 million people globally, leaving patients to navigate a diagnostic odyssey constrained by clinical scarcity. This study provides a replicable framework for deploying trustworthy diagnostic AI across complex, high-stakes, and underserved medical domains.

Limitations

The evidence is limited to a single preprint (arXiv:2610.24024v1) with no peer review or clinical validation. Results represent a snapshot of a specific framework evaluation rather than long-term performance or real-world applicability.
