Abstract
Justin Rubio and colleagues report results of a genome-wide association study of multiple sclerosis using cases from Australia and New Zealand. Their findings confirm several published risk loci for MS and identify two new risk loci on chromosomes 12 and 20. To identify multiple sclerosis (MS) susceptibility loci, we conducted a genome-wide association study (GWAS) in 1,618 cases and used shared data for 3,413 controls. We performed replication in an independent set of 2,256 cases and 2,310 controls, for a total of 3,874 cases and 5,723 controls. We identified risk-associated SNPs on chromosome 12q13–14 (rs703842, P = 5.4 × 10−11; rs10876994, P = 2.7 × 10−10; rs12368653, P = 1.0 × 10−7) and upstream of CD40 on chromosome 20q13 (rs6074022, P = 1.3 × 10−7; rs1569723, P = 2.9 × 10−7). Both loci are also associated with other autoimmune diseases1,2,3,4,5. We also replicated several known MS associations (HLA-DR15, P = 7.0 × 10−184; CD58, P = 9.6 × 10−8; EVI5-RPL5, P = 2.5 × 10−6; IL2RA, P = 7.4 × 10−6; CLEC16A, P = 1.1 × 10−4; IL7R, P = 1.3 × 10−3; TYK2, P = 3.5 × 10−3) and observed a statistical interaction between SNPs in EVI5-RPL5 and HLA-DR15 (P = 0.001).Keywords
