NOS3 and coronary artery disorder: In summary, the results of this pilot GWAS provide novel evidence for increased arrhythmic SCA risk in the setting of CAD due to genetic variation in six genes without prior evidence of cardiovascular effect (ACYP2, ZNF385B, GRIA1, AP1G2, DEGS2, KCTD1) and in a number of genes with strong prior evidence of arrhythmic and/or cardiovascular effects (ESR1, CACNA1C, NOS3, NOS1AP, CSMD2, AGTR1, KCNQ1, KCNE1).
