In addition, we also found AF-associated upregulation of MYH7 (Nielsen et al., 2018; Thomas et al., 2019), KCNK3 (Schmidt et al., 2015, 2017), SLC8A1 (Schotten et al., 2002; Gaborit et al., 2005), and downregulation of CACNA1D (Van Wagoner and Nerbonne, 2000; Gaborit et al., 2005). Here, KCNK3 is linked to atrial fibrillation.
