Finally, nine candidate genes related to methylation were obtained, BASP1, VEGFA, MUC4, HLA-DRB1, TJP2, BCR, ANGPTL4, PKD1, and HK2, which may be involved in the pathogenesis of CHD (Figure 6B) and these genes information was provided in Supplementary Table 3. This evidence concerns the gene TJP2 and coronary artery disorder.
