This study, which shows for the first time a functional HLA-DQA1/DRB1 mixed isotype heterodimer and its potential association with disease susceptibility, provides a rationale for a potential effect on MS risk from DQA1*01:02 through functional DQA1*01:02;DRB1*15:01 antigen presentation.

Additionally, three haplotypes associated with a lower risk for MS were identified, exhibiting DRB1*0101-DQA1*0101-DQB1*0501 the strongest negative association with MS [12% in controls vs. 3.8% in MS, Pc = 0.00047, OR = 0.290 (95% CI = 0.160–0.528)], and suggesting, therefore, a putative protective role for this haplotype in the population under study.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) with supposedly autoimmune features known to be associated with a specific HLA DR-DQ haplotype (DR15, DQ6, or HLDRB1*1501,DRB5*0101,DQA1*0102,DQB1*0602).

Our results suggested that the effect of the DRB1*1501,DQA1*0102,DQB1*0602 haplotype on the susceptibility to MS is additive, perhaps reflecting that development of the disease is facilitated by a high density surface expression of the antigen presenting molecules encoded by this haplotype.
