HLA-DRB1 and HIV infectious disease: Reported alleles to include HLA-DQB1*03:02, HLA-DQB1*06:04 and HLA-DQB1*02:01 have been related with rapid disease progression and high risk of HIV infection, while HLA-DP1 *01:01, HLA-DP1*03:01, HLA-DRB1*01:01 and HLA-DRB1*01:02 are related with slower disease progression and a protective effect against HIV infection (Just et al., 1995; Just et al., 1996; Achord et al., 1997).
