COL1A2 and familial dilated cardiomyopathy: The results indicated that many genes, including ASPN (AUC = 0.841, P < 0.0001), COL1A2 (AUC = 0.809, P < 0.0001), DPT (AUC = 0.844, P < 0.0001), MYH6 (AUC = 0.894, P < 0.0001),NPPA (AUC = 0.863, P < 0.0001), NPPB (AUC = 0.903, P < 0.0001), PRELP (AUC = 0.816, P < 0.0001), PRKACA (AUC = 0.822, P < 0.0001) and YY1AP1 (AUC = 0.891, P < 0.0001), can efficiently distinguish DCM cardiac tissues from normal cardiac tissues (Figures 7A–I).
