The 3 new loci do not have a strong cis effect on RNA expression in PBMCs. Ten other susceptibility loci had a suggestive p < 1 × 10−6, some of these loci have evidence of association in other inflammatory diseases (ie, IL12B, TAGAP, PLEK, and ZMIZ1). Interpretation: We have performed a meta-analysis of GWAS in MS that more than doubles the size of previous gene discovery efforts and highlights 3 novel MS susceptibility loci. These and additional loci with suggestive evidence of association are excellent candidates for further investigations to refine and validate their role in the genetic architecture of MS.]]> Sat 24 Mar 2018 08:17:22 AEDT ]]> Closing the case of APOE in multiple sclerosis: no association with disease risk in over 29 000 subjects https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25354 Sat 24 Mar 2018 07:24:42 AEDT ]]> Analysis of immune-related loci identifies 48 new susceptibility variants for multiple sclerosis https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23578 −4). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703 healthy controls. In these 80,094 individuals of European ancestry, we identified 48 new susceptibility variants (P < 5.0 x 10−8), 3 of which we found after conditioning on previously identified variants. Thus, there are now 110 established multiple sclerosis risk variants at 103 discrete loci outside of the major histocompatibility complex. With high-resolution Bayesian fine mapping, we identified five regions where one variant accounted for more than 50% of the posterior probability of association. This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals.]]> Sat 24 Mar 2018 07:12:44 AEDT ]]>
