title: Associations between oxidized-lipoprotein receptor 1 G501C and 3'-UTR-C188T polymorphisms and coronary artery disease: a meta-analysis.
abstract: OBJECTIVE
  Previous case-control studies have suggested that the variations of the oxidized-lipoprotein receptor 1 (OLR1) gene (G501C, 3'-UTR-C188T) are associated with coronary artery disease (CAD). However, other studies have not confirmed this relationship. The objective of this study was to assess the relationship between OLR1 variations and CAD.
  
  
  METHODS
  We conducted a meta-analysis. Databases, including PubMed, EMbase, Chinese Biological Medical Literature Database (CBM), and China National Knowledge Infrastructure (CNKI), were searched to obtain genetic association studies. Data were extracted by two authors, and pooled odds ratios (OR) with 95% CI were calculated.
  
  
  RESULTS
  The meta-analysis included 8 studies with 4,963 cases and 14,864 controls for 3'-UTR-C188T and 9 studies with 5,660 cases and 15,405 controls for G501C. The pooled OR for 3'-UTR-188T was 1.29 (95% CI 1.05-1.58, p = 0.02) compared to the C allele in the dominant model, and it was 1.38 (95% CI 1.09-1.74, p = 0.007) in the recessive model. The pooled OR for 501C was 0.79 (95% CI 0.57-1.10, p = 0.16) compared to the G allele in the dominant model, and it was 0.86 (95% CI 0.71-1.04, p = 0.12) in the recessive model. No publication bias was found in the present meta-analysis.
  
  
  CONCLUSIONS
  The synthesis of available evidence supports that OLR1 3'-UTR-188T increases the susceptibility to CAD. However, G501C is not associated with CAD.
