摘要
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system with presumed autoimmune origin, triggered by genetic and environmental risk factors. A recent genome-wide association study conducted on MS identified new biallelic markers outside the HLA (human leucocyte antigen) region involved in disease susceptibility: rs1109670 (DDEF2); rs1458175 (PDZRN4); rs1529316 and rs2049306 (CSMD1); rs16914086 (TBC1D2); rs1755289 (SH3GL2); rs1841770 (ZIC1); rs651477 (EN1); rs7607490 (TRIB2); rs397020 (C20orf46); rs908821 (SLC25A36); rs7672826 (MGC45800) and rs9523762 (GPC5). We aimed at replicating these top association signals in a Spanish cohort of 2863 MS patients and 2930 sex-and age-matched controls. Only rs9523762 mapping in the GPC5 gene was significantly associated (G allele, P = 1.6 x 10(-5); odds ratio (95% confidence interval) = 1.23 (1.12-1.36)), supporting a role for this proteoglycan in MS predisposition. The independent replication of association signals to validate data generated by genome-wide association scans is a first step in the effort to improve patient care.
