title: Anthrax toxin receptor 2 gene (ANTXR2) rs4333130 is associated with ankylosing spondylitis.
abstract: Results of recent published studies on the association between the ANTXR2 rs4333130 polymorphism and the risk of ankylosing spondylitis (AS) have often been conflicting. To make a more precise estimation of the potential relationship, a meta-analysis was performed. We conducted a comprehensive search in the electronic database of PubMed and Embase to retrieve relevant articles. Nine studies including 14,523 cases and 34,421 controls were finally selected in this meta-analysis. ANTXR2 rs4333130 was significantly associated with a decreased risk of AS (OR=0.87; 95% CI, 0.84-0.90; P<0.00001). In the subgroup analysis by race, ANTXR2 rs4333130 was significantly associated with a decreased risk of AS in both Asian (OR=0.80; 95% CI, 0.65-0.99; P=0.04) and Caucasian (OR=0.87; 95% CI, 0.84-0.90; P<0.00001). In the subgroup analysis by HLA-B27 status, HLA-B27 positive individuals with ANTXR2 rs4333130 showed decreased AS risk (OR=0.89; 95% CI, 0.83-0.96; P=0.002). However, HLA-B27 negative individuals with this polymorphism did not showed decreased AS risk (OR=0.96; 95% CI, 0.88-1.06; P=0.44). In conclusion, this meta-analysis suggested a significant association between ANTXR2 rs4333130 polymorphism and AS risk.
