We also assessed 4 recently published gene associations for sudden cardiac arrest, validating NOS1AP (p = 4.50 × 10-2, OR = 1.15, 95% CI:1.003, 1.326), CSMD2 (p = 6.6 × 10-3, OR = 2.27, 95% CI:1.681, 2.859), and AGTR1 (p = 3.00 × 10-3, OR = 1.13, 95% CI:1.042, 1.215). This evidence concerns the gene NOS1AP and sudden cardiac arrest.
