Genomic Prediction Models for Celiac Disease Risk Across Six European Cohorts

Gad Abraham developed a genomic risk score (GRS) model for celiac disease using statistical learning on genome-wide SNP profiles from six European cohorts. The model achieved cross-validation AUCs of 0.87–0.89 and independent replication AUCs of 0.86–0.9, explaining 30–35% of disease variance. This proof-of-concept demonstrates the potential for genomic-based risk stratification to improve clinical diagnostic pathways.
