ABSTRACT
【Objective】 To explore the association of HLAII(-DRB1, -DQB1, -DPB1) alleles and haplotypes polymorphisms with acute myeloid leukemia (AML) in northern Han population. 【Methods】 A total of 308 AML (non-M3) patients (patient group) and 824 unrelated healthy bone marrow donors (control group) were genotyped at a high-resolution level using polymerase chain reaction-sequence-based typing (PCR-SBT), next-generation sequencing (NGS) with Ion Torrent S5 platform and sequence specific oligonueleotide probes (SSO) with LABScan® 3D platform. Frequencies of HLA II alleles and haplotypes were calculated with Arlequin 3.5.2.2 software. The odds ratio (OR) of AML was also calculated for case-control study. 【Results】 By χ2 test and correction, an increased frequency of HLA-DRB1*07∶01(14.61% vs 9.53%, P<0.01), HLA-DQB1*02∶02(12.82% vs 8.31%, P<0.01), HLA-DQB1*06∶02(11.53% vs 8.74%, P<0.05) and HLA-DPB1*17∶01(5.84% vs 3.16%, P<0.01) among AML patients was discovered in significant comparison with the control group. After Bonferroni correction, the frequency of HLA-DRB1*07∶01(Pc<0.05), HLA-DQB1*02 02(Pc<0.05) and HLA-DPB1*17∶01(Pc<0.05) in AML patients were still higher than those in the control group, which had a strong positive correlation with AML (OR=1.62 (95% CI=1.23~2.14), 1.62(95% CI=1.21~2.18) and 1.91(95% CI=1.23~2.94), respectively. The frequency of two loci haplotype HLA-DRB1*07∶01-DQB1*02∶02 in AML patients was still higher than that of the control group after Bonferroni correction (12.66% vs 8.19%, Pc<0.05). The frequency of the 3 loci haplotype HLA-DRB1*07∶01-DQB1*02∶02-DPB1*17∶01, as a susceptible haplotype of AML, was higher than that of the control group and was strongly correlated with AML. 【Conclusion】 The data on the association of HLA II (-DRB1, -DQB1, -DPB1) alleles and haplotype polymorphisms with AML in northern Han populations was obtained in this study. HLA-DRB1*07∶01, HLA-DQB1*02∶02, HLA-DPB1*17∶01 and the HLA-DRB1*07∶01-DQB1*02∶02-DPB1*17∶01 haplotype are the risk genes and susceptible extended haplotype for AML. The risk prediction based on HLA haplotype might be more accurate than that based on single allele.
