This article aims to evaluate the relationship between allele polymorphism of HLA-DQ, DR and TID in the Chinese population. Methods The odds ratios （ORs） of HLA-DQ, DR allele distributions in patients with T1D were analyzed against healthy controls. All the relevant studies in Pubmed and CNKI were identified, and poor qualified studies were excluded. The meta-analysis software REVMAN 4.2 was applied for investigating heterogeneity among individual studies and for summarizing all the studies. The publication bias were also evaluated. Results DQA1＊0301, DQA1＊0501, DQB1＊0201, DQB1＊0302 were the susceptible alleles （all P 〈0.05） in the Chinese population, their merger ORs 2.40, 3.15, 3.66, and 2.67 respectively. DQA1＊0103, DQA1＊0201, DQA1＊0401, DQB1＊0301, DQB1＊0402, DQB1 ＊0501, DQB1＊0503, DQB1＊0601 and DQB1＊0602 were the protective alleles （P 〈0.05）, their merger ORs were 0.11, 0.45, 0.30, 0.38, 0.23, 0.37, 0.25, 0.48, and 0.30 respectively. In serum level, DR3, DR4, DR9 alleles were the susceptible alleles （all P 〈0.05） and their merger ORs were 5.58, 1.53, 1.66, 29.78, and 6.65 respectively. HLA-DR2, DR5, and DR7 alleles were the protective alleles （all P 〈0.05） and their merger ORs were 0.39, 0.51, and 0.50. In genetic type level, DRB1＊04, DRB1＊0301, DRB1＊0901 were the susceptible alleles （all P 〈0.05） and their merger ORs were 2.19, 6.43, 1.31, 3.83, and 8.08. DRBI＊07, DRBI＊08, DRB1＊12, DRB1＊13, DRB1＊14, DRB1＊16, DRBI＊0406 alleles were the protective alleles （all P 〈0.05） and their merger ORswere 0.44, 0.27, 0.45, 0.13, 0.19, 0.40, and 0.27 respectively. Conclusions In the Chinese population, some HLA-DQ, DR alleles are relevant to T1D which are not totally the same as non-Chinese populations.展开更多
