CDKN2B and coronary artery disorder: The 9p21.3 risk haplotype at ANRIL/CDKN2B-AS1 had initially been identified by GWAS of CAD (24), and was shortly later identified by Schaefer et al. as one of the first genetic risk factors of AgP (17, 25–27) [see (Table 1) for a comparison of the association statistics of the relevant 9p21.3 lead SNPs related to AgP and coronary heart disease].
