Of the 17 IMSGC SNPs, five SNPs showed genome-wide significant association with MS: HLA-DRA (P=8E-124), IL7R (P=6E-09), IL2RA (P=1E-11), CD58 (P=4E-09) and CLEC16A (P=3E-12).
Interactions between both HLA-DMB and the HLA-DRA promoter and other reported MS susceptibility loci were examined (TCRBV polymorphisms, HLA-DQA1 and HLA-DQB1).
