The SMC-dominant (Fig. 5f,g) GRN177 contained 43 key drivers and 19 CAD genome wide association studies (GWAS) candidate genes (ANKRD6, ARHGAP26, CNNM2, FNDC3B, GEM, HECA, MAP1B, MAP3K7CL, NBEAL1, NEDD9, NT5C2, PALLD, PDLIM5, PPP1R12B, PREX1, RAB23, RUNX2, SHROOM3, and SLC22A3) and contributed to 2.16% of CAD H2 (Fig. 5g). The gene discussed is MAP1B; the disease is coronary artery disorder.
