    Abstract:
    BACKGROUND: Inflammation plays an important role in the pathophysiology of coronary artery disease (CAD). NF-κB is a central regulator of inflammation. Thus the aim of this study was to conduct a systematic review and meta-analysis investigating whether the polymorphism in the NFKB1 promoter region (NFKB1-94ins(I)/del(D)ATTG, rs28362491) is associated with CAD susceptibility. METHODS: PubMed, Embase, Cochrane Library and CNKI databases were searched up to 30 July 2015. All observational case-control studies that investigated the association of NFKB1 I/D polymorphism and CAD risk were included. Two reviewers independently selected the studies and extracted the data. RESULTS: A total of 7 studies were included in this meta-analysis. Comparison between alleles showed a 13% increased risk of CAD for D vs. I (OR = 1.13, 95% CI 1.06-1.19, PH = 0.318), and comparisons among genotypes showed a 26% increased risk of CAD for DD vs. II (OR = 1.26, 95% CI 1.12-1.43, PH = 0.125) and in the heterozygote model ID vs. II had an 11% increased risk (OR = 1.11, 95% CI 1.01-1.21, PH = 0.751). In the dominant model the risk of CAD risk was reduced by 13% (OR = 0.87, 95%CI 0.80-0.95, PH = 0.814) across the total population. Subgroup analysis by ethnicity indicated that the additive model was associated with a 21% increased risk for CAD in the Caucasian population (OR = 1.21, 95% CI 1.09-1.34, PH = 0.522), while the homozygote model gave a 47% increased risk for CAD in Asian population (OR = 1.47, 95% CI 1.21-1.78, PH = 0.314). CONCLUSIONS: Our results indicated that the NFKB1-94ins/del ATTG polymorphism was associated with susceptibility to CAD in both Asian and Caucasian populations.
