Epistatic interactions between both parental alleles in the DRB1 loci have been shown to modify the MS susceptibility risk. This study investigated the frequencies of various HLA-DRB1 genotypes, their impact on MS susceptibility and their correlation with the clinical severity in a Spanish population.MethodsA genotype was considered as the combination of the two parental DRB1 alleles. We compared the frequencies of the genotypes in a sporadic MS population (n=380) with those of an unrelated healthy control cohort (n=1088). We correlated the different genotypes with the age at onset, gender distribution, symptoms at onset, course of the disease and progression severity by means of the time to reach the progressive phase and EDSS scores of 3 and 6.ResultsWe found 81 different genotypes. There were four different MS-predisposing genotypes. Three of them contained the DRB1*15 allele (DRB1*03/15, DRB1*04/15, and DRB1*08/15) and the fourth was homozygote for the DRB1*03 allele. The highest odds ratio was found with the genotype DRB1*08/15 (OR=3.88, 95% CI=1.83-8.26, p<0.01), followed by DRB1*03/03 (OR=3.15, 95% CI=1.93-5.14, p<0.01), DRB1*03/15 (OR=2.72, 95% CI=1.88-3.94, p<0.01) and DRB1*04/15 (OR=2.54, 95% CI=1.64-3.98, p<0.01). The DRB1*01/04 and the DRB1*15/15 genotypes were associated with a shorter time to reach an EDSS score of 6.ConclusionsOur results show the importance of epistatic interactions among the HLA-DRB1 alleles, modifying the risk for MS as well as its clinical severity."xsd:string |
