Identification of shared genetic loci for asthma, allergic rhinitis, and pollinosis in East Asians.

ABSTRACT: Asthma, allergic rhinitis, and pollinosis are prevalent respiratory conditions that often co-occur, suggesting common genetic and environmental causes. While significant progress has been made in identifying genetic loci in European populations, the genetic architecture in East Asian populations remains poorly understood. Using GWAS summary statistics from BioBank Japan, we performed multi-trait genome-wide association studies (MTAG) to quantify the genetic overlap among asthma, allergic rhinitis, and pollinosis in East Asians. Genetic correlation analysis revealed significant positive correlations among the three conditions, and stratified LDSC (Linkage Disequilibrium Score Regression) analysis identified heritability enrichments in Blood/Immune and Digestive tissues. We discovered novel
