HLA-DQ, DR allele polymorphism of type 1 diabetes in the Chinese population: a meta-analysis

Background Type 1 diabetes （TID） is a multifactorial disease. 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.     

Relationship between HLA-DRB1 and DQ alleles and the genetic susceptibility to type 1 diabetes

Objective　To study the relationship between human leukocyte antigen (HLA)-DRB1 and DQ alleles and the genetic susceptibility of type 1 diabetes in North Chinese children. Methods　Polymerase chain reaction (PCR) techniques were used to amplify the second exon of DRB1 and DQ alleles, after which sequence specific olignucleotide probe (SSOP) dot blot hybridization techniques were used to analyze the amplified products. Results　DRB1*0301, DQA1*0301, DQB1*0201 alleles and DRB1*0301-DQA1*0501-DQB1*0201 haplotype were significantly increased in patients, while DQA1*0103 and DQB1*0601 alleles were significantly increased in controls. The distribution of DR4 and DR9 haplotypes in patients and controls were not significantly different, but DR3/DR4 and DR4/DR9 heterozygotes were significantly increased in patients. Conclusions　DRB1*0301, DQA1*0301 and DQB1*0201 confer susceptibility while DQA1*0103 and DQB1*0601 confer protection to type 1 diabetes. DRB1*0301-DQA1*0501-DQB1*0201 haplotype offers a predisposition to type 1 diabetes in North Chinese. Although the distribution of DR4 and DR9 in patients and controls had no significant difference, DR3/DR4 and DR3/DR9 heterozygotes were significantly increased in patients, showing that the susceptive effects of DR3 and DR4 or DR4 and DR9 haplotypes could be added up.     

HLA-DQ A1, -DQB1 and -DRB1 gene polymorphism--in Malay type 1 diabetes mellitus patients and their use for risk prediction

HLA-DQA1, -DQB1, and -DRB1 gene polymorphism were analyzed to study type 1 DM susceptibility in Malay patients from Southeast Asia (Malaysia and Singapore). Patients showed significant increases in the occurrence of DQA1*0501 (50.7% vs. 20.4%; RR = 3.97; Pc < 0.01), DQB1*0201 (48% vs. 19.1%; RR = 3.86; Pc < 0.05), and DRB1*0301 (38.7 vs. 6.8%; RR = 8.36; 95% Pc < 0.05). Conversely, significant decreases were noted in the occurrence of DQA1*0601 (14.7% vs. 35.2%; RR = 0.33; Pc = 0.008) and DQB1*0601 (4% vs. 23.5%; RR = 0.16; Pc < 0.05) in type 1 DM patients. Using a logistic regression model, we derived a risk prediction model for type 1 DM in our indigenous Malay population based on the identified HLA genotypes. The RR for type 1 DM increases by a factor of 5.68 for every unit increase in the number of DRB1*0301 allele (P < 0.001), and decreases by a factor of 0.18 per unit increase in the number of DQB1*0601 allele (P < 0.001). After adjusting for these two HLA genotypes, DQA1*0501, DQB1*0201 and DQA1*0601 were not statistically significant as risk predictors. The lower incidence of type 1 DM in the Malay population may be contributed by the genotypic combinations of DR and DQ genes as well as the linkage disequilibria between susceptible and protective alleles.
