HLA-DRB1 and systemic lupus erythematosus: Table 3 shows a large variance in the putative HLA-DRB1/DQB1 haplotypes among our groups (54 haplotypes) with an increase in the frequency of DRB1*0301/DQB1*0201 (p = 0.037, OR = 2.20) and DRB1*1501/DQB1*0601 (p < 0.001, OR = 9.84) haplotypes in SLE patients in comparison to controls.
