Transcriptomic profiling of heart samples by RNA-Seq. The number of genes and their relative expression levels represented by transcript normalized read counts in controls (A) and ICM patients (B). (C) Principal Component Analysis of heart samples were cluster on the basis of their gene expression profile. Samples are represented by points at CNT for controls and ICM for patients. Proportions of variances showed that 0.95% of the differences among the sample groups could be explained by PCA component 1 (PC1) and 0.233% by PCA component 2 (PC2).
