The most interesting differentially expressed cardiac genes are CACNA2D1, CASQ2, CDH2, DSC2, DSP, GJA5, GPD1L, KCNE3, LAMA4, MYOZ2, NEXN, SCN4B, SDHA, SLMAP and SNTA1, as mutations in these genes have been reported in ion channelopathies or cardiomyopathies [48, 49]. This evidence concerns the gene DSP and cardiomyopathy.
