摘要Several genome-wide association studies (GWAS) identified new single nucleotide polymorphisms (SNPs) with susceptibility to Tuberculosis (TB). However, many of them were not replicated across ethnic groups. The cause of this phenomenon of genetic heterogeneity is uncertain. Here, we attempted to replicate and evaluate the mechanism that causes genetic heterogeneity in several putative TB predisposition loci found by previous GWAS, including chromosome 18q, ASAP1, DUSP14, and HLA-DQA1. A Chinese cohort of 1200 TB patients and 1280 population controls were genotyped. The results showed that genetic predisposition to TB might operate in an age-specific manner. While no significant association was found in the whole samples, a SNP of HLA-DQA1, rs9272785, showed suggestive association within the young-onset TB subgroup (onset at 20–40 years of age, N = 396). The results provide support for the hypothesis that there are different pathogenesis mechanisms causing clinical TB disease in different age groups, and that genetics probably play a substantial role only in young-onset TB.
