title: CTLA-4 gene and the susceptibility of multiple sclerosis: an updated meta-analysis study including 12,916 cases and 15,455 controls.
abstract: Abstract Cytotoxic T-lymphocyte antigen-4 (CTLA-4) is a cell surface molecule involved in the regulation of T cells. Single-nucleotide polymorphisms (SNPs) of CTLA-4 gene are known to be associated with susceptibility to several autoimmune diseases, including multiple sclerosis (MS). This study aimed to evaluate the association between CTLA-4 and the risk of MS. Comprehensive meta-analysis was applied to case-control studies of the association between MS and CTLA-4 to assess the joint evidence for the association, the influence of individual studies, and evidence for publication bias. The authors searched PubMed, MEDLINE, Cochrane Library, and reference lists of relevant studies to September 2013. In all, the allele or genotype analysis showed no significant association between + 49A/G, - 318C/T, or CT60A/G and MS. And the subgroups of the three polymorphisms divided into Americas, Europe, and Asia showed no significant association with MS. The sensitivity analysis or publication bias analysis showed no significance. In conclusion, this comprehensive meta-analysis suggested that + 49A/G, - 318C/T, or CT60A/G polymorphism, either in total analysis or in subgroup analyses, has no significant association with MS disease.
