One of the loci for week 1 FS near Lrp12 and Zfpm2 on chromosome 15 has previously been shown in a small human GWAS to be associated with sudden cardiac arrest due to ventricular tachycardia and ventricular fibrillation in patients with coronary artery disease (p-value = 1 x 10−6) [44]. Here, ZFPM2 is linked to ventricular fibrillation.
