Amongst the different GWAS for cardiovascular disease performed during the last years, chemokine CXCL12 gene polymorphisms have been associated with CAD (e.g., Samani et al., 2007; Kathiresan et al., 2009; Franceschini et al., 2011; Schunkert et al., 2011). This evidence concerns the gene CXCL12 and coronary artery disorder.
