To explore the relationship between HLA-A, -B, -C, -DRB1, -DQB1 gene polymorphism and aplastic anemia （AA）of 65 cases in Northern China.The high resolution genotyping of HLA-A, -B, -C, -DRB1, -DQB1 alleles in 65 AA patients and 772 healthy controls was performed with polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO), the relationship between HLA-A, -B, -C, -DRB1, -DQB1 gene polymorphism and aplastic anemia was analyzed by Pearson Chi-square，Continuity Correction， Two-sided Fisher's Exact Test and Odds Ratio.The HLA-B*1302（10% vs 4.21%）, B*3501（7.69% vs 3.89%）, DRB1* 0701（10% vs 4.73%）, DRB1*0901（19.23% vs 7.58%）, DQB1*0202（9.23% vs 3.76%） gene frequency in AA patients was higher than those in health controls, the difference was statistically significant (P0.05), the χThe polymorphism of HLA-A, -B, -DRB1, -DQB1 alleles is associate with AA in these patient cases, the HLA-B*1302, HLA-B*3501, HLA-DRB1*0701, HLA-DRB1*0901 and HLA-DQB1*0202 may be sensitive genes to AA, while the HLA-A*3303 and HLA-DQB1*0302 may be protective genes on AA. |
