Common concomitant gene mutations included DNMT3A mutation, TET2 mutation, ASXL1 mutation, FAT1 mutation, EP300 mutation, etc., of which the proportion of patients with TET2 mutation in the AF group was significantly higher when compared with the no‐AF group (p < 0.05) (Table S2). This evidence concerns the gene FAT1 and atrial fibrillation.
