The second isoform was significantly upregulated (logFC, 0.73; adj.P, 3.9e–2) and differed from the canonical TPM1 sequence by residues 41–80 by MXE, corresponding to the TPM1 kappa isoform (P09493–6) on SwissProt that was previously found in single-target immunobiological studies to be increased in dilated cardiomyopathy patients (Rajan et al., 2010). This evidence concerns the gene TPM1 and dilated cardiomyopathy.
