Abstract
The effect of HLA alleles on the outcome of multiple sclerosis (MS) has been widely investigated; however, results are conflicting and no consistent correlation has been established. This study evaluated the association between the HLA DR2 haplotype in patients with primary progressive MS (PPMS) and the effect of alleles on progression. An association was found between PPMS and the DR2 and DRB1*1501 and DQB1*0602 alleles. Severe morbidity was found in DRB1*1501-positive PPMS patients. This exploratory study raises new hypotheses for future research and emphasizes the need to investigate possible candidate genes other than HLA that may contribute towards heterogeneity in the course of the disease.
