Abstract

We performed a replication study in 883 Austrian multiple sclerosis (MS) patients and 972 control individuals for 25 previously risk-associated loci (39 SNPs). Two loci, rs1109670 (DDEF2/MBOAT2, p<0.02) and rs16914086 (TBC1D2, p<0.05), are replicated here for the first time. Furthermore, we tested all 39 SNPs for association with age at disease onset and measures of disease severity. We observed a trend for association of rs3135388 (HLADRB1* 1501, p<0.01), rs7090530 (IL2RA, p<0.026) and rs1841770 (ZIC1, p<0.017) with a younger age at MS onset and of rs12044852 (CD58, p<0.035) with shorter time to reach EDSS6.
