Similar correlations were observed between FABP3 gene and autophagy-related genes even when they were analyzed separately for the SR group (FABP3 and ATG5: r2 = 0.510, p<0.001; FABP3 and ULK1: r2 = 0.622, p<0.001; FABP3 and BCLN1: r2 = 0.740, p<0.001; FABP3 and LC3: r2 = 0.384, p<0.001) and the AF group (FABP3 and ATG5: r2 = 0.670, p<0.001; FABP3 and ULK1: r2 = 0.790, p<0.001; FABP3 and BCLN1: r2 = 0.768, p<0.001; FABP3 and LC3: r2 = 0.534, p = 0.005). This evidence concerns the gene FABP3 and atrial fibrillation.
