Genome-wide association study reveals a novel tuberculosis susceptibility locus in multiple East Asian and European populations

Abstract

Background: Tuberculosis (TB) continues to be a leading cause of morbidity and mortality worldwide. Although numerous genome-wide association studies (GWAS) have explored TB susceptibility across various ethnic groups, multi-population replication of findings has been very limited, particularly outside the HLA region, and a significant portion of TB heritability remains unexplained. Methods: We conducted GWAS in the Singapore Chinese and Vietnamese, followed by a comprehensive meta-analysis incorporating 4 independent East Asian datasets (N = 11,841 cases; N = 197,373 controls). The transferability of any identified association was assessed using summary statistics from independent European ..
