Multi-trait Polygenic Probability Risk Score Enhances Glaucoma Prediction Across Ancestries.

ABSTRACT: Primary open-angle glaucoma (POAG) remains the leading cause of irreversible blindness worldwide, with early detection crucial for preventing vision loss. However, current risk assessment methods have limited predictive power. Here, we present a multi-trait polygenic probability risk score (PPRS) approach that integrates multiple glaucoma-related traits and leverages functional genomic annotations to enhance POAG prediction across diverse ancestries. We constructed PRSs for POAG, intraocular pressure (IOP), vertical cup-to-disc ratio (VCDR), and retinal nerve fiber layer (RNFL) thickness using extensive genomic coverage (>7 million variants) and 96 functional annotations through the SBayesRC method. Validation in the UK Biobank (n=324,713, European ancestry) and Mexican American Glaucoma G
