HLA-DRB1 and HIV infectious disease: We identified significant associations between HLA-C*07:01 (p = 0.0101, OR = 10.222), HLA-DQA1*03:02 (p = 0.0051, OR = 5.297), and HLA-DRB1*09:01 (p = 0.0119, OR = 4.788) and susceptibility to HIV infection, while HLA-DQB1*03:419 (p = 0.0478, OR = 0.327) was associated with protection from HIV exposure (Table 3).
