Previous studies revealed that the down‐regulation of miR‐26 may promote AF by targeting KCNJ2. 26Our previous studies have shown that lncRNAs can modulate the electrical remodelling of AF by targeting the calcium channel‐encoding gene CACNA1C. 18Based on this, we considered that TCONS‐00106987 could affect KCNJ2 expression by endogenously competing with miR‐26. Here, KCNJ2 is linked to atrial fibrillation.
