/manager/Index ${session.getAttribute("locale")} 5 Genetic variants are major determinants of CSF antibody levels in multiple sclerosis /manager/Repository/uon:27383 -16). Furthermore, we identify a novel association signal of rs9807334, near the ELAC1/SMAD4 genes, for oligoclonal band status (P = 8.45 x 10-7). The previously reported association of the immunoglobulin heavy chain locus with immunoglobulin G index reaches strong evidence for association in this data set (P = 3.79 x 10-37). We identify two novel associations in the major histocompatibility complex region with immunoglobulin G index: the rs9271640*A-rs6457617*G haplotype (P = 1.59 x 10-22), shared with oligoclonal band status, and an additional independent effect of rs6457617*G (P = 3.68 x 10-6). Variants identified in this study account for up to 2-fold differences in the odds of being oligoclonal band positive and 7.75% of the variation in immunoglobulin G index. Both traits are associated with clinical features of disease such as female gender, age at onset and severity. This is the largest study population so far investigated for the genetic influence on antibody levels in the cerebrospinal fluid in multiple sclerosis, including 6950 patients. We confirm that genetic factors underlie these antibody levels and identify both the major histocompatibility complex and immunoglobulin heavy chain region as major determinants.]]> Sat 24 Mar 2018 07:34:11 AEDT ]]> Increased DNA methylation of SLFN12 in CD4⁺ and CD8⁺ T cells from multiple sclerosis patients /manager/Repository/uon:37082 Fri 14 Aug 2020 14:27:43 AEST ]]>
