Of the 38 known CHD loci that colocalized with a related trait, 8 are reported to have a single causal variant26, of these we identified the same CHD-associated variant (or one in LD with either r2 > 0.8 or |D′|> 0.8)15 at seven loci (SORT1, PHACTR1, ZC3HC1, CDKN2B-AS1, KCNE2, CDH13, APOE). This evidence concerns the gene KCNE2 and coronary artery disorder.
