Healthcare AI & Federated Learning
Training Together, Diagnosing Better: AI for Rare Diseases
Discover how Federated Learning (FL) revolutionizes the diagnosis of rare diseases like Collagen VI–Related Dystrophies (COL6-RD) by enabling collaborative model training across diverse, decentralized datasets without compromising patient privacy.
Executive Impact: Unlocking Diagnostic Precision with Federated AI
This study demonstrates a novel global Federated Learning initiative for COL6-RD, leveraging immunofluorescence microscopy images. By training an ML model across two international organizations, we achieved an F1-score of 0.82, significantly outperforming single-organization models (0.57–0.75). This approach enhances diagnostic utility, generalizability, and addresses critical data scarcity and privacy concerns in rare disease research.

Traditional machine learning for rare diseases faces severe limitations due to data scarcity and fragmentation across institutions. Centralized data aggregation raises significant privacy and regulatory concerns. Federated Learning (FL) offers a paradigm shift by allowing models to train on decentralized datasets locally, sharing only model updates rather than raw patient data. This fundamentally improves data privacy and regulatory compliance, making multi-institutional collaboration feasible for rare disease diagnostics.
Collagen VI-Related Dystrophies (COL6-RD) are a spectrum of rare muscular dystrophies. Definitive diagnosis traditionally relies on molecular genetic testing, which is complex due to various pathogenic variants and unknown significance. This study applies ML to collagen VI immunofluorescence microscopy images to classify COL6-RD patient images into three primary pathogenic mechanisms: exon skipping, glycine substitution, and pseudoexon insertion. This innovative approach provides a quantitative, mechanism-based diagnostic tool.
The Federated Learning model achieved a superior F1-score of 0.82, significantly outperforming single-organization models (0.57–0.75). This demonstrates FL's ability to substantially improve diagnostic utility and generalizability across diverse cohorts and imaging characteristics. The model's robustness and accuracy support its potential for clinical application, especially in interpreting variants of uncertain significance and guiding sequencing strategies.

NIH & UCL Collaboration: A Federated Success
The collaboration between the National Institutes of Health (NIH) and University College London (UCL) exemplifies FL's power. Despite distinct imaging protocols and patient demographics, the FL model significantly boosted UCL's diagnostic performance, particularly in identifying control images previously misclassified. This multi-institutional effort validates FL as a robust solution for rare disease research where data heterogeneity and scarcity are prevalent.
