HLA-DRB1 and systemic lupus erythematosus: On the other hand, the following HLA-DRB1/DQB1 putative haplotypes are suggested to be protective haplotypes since they were totally absent in the SLE patients: DRB1*0403/DQB1*0302 (p = 0.034, OR = 0.05), DRB1*0701/DQB1*0201 (p = 0.001, OR = 0.24), DRB1*1301/DQB1*0603(p = 0.028, OR = 0.04) and DRB1*1501-DQB1*0602 (p = 0.028, OR = 0.04).
