In the GSE120895 dataset, the violin diagram illustrates that in comparison to the control group, the gene expression levels of SLC25A5, CAPN1, IFNGR2 were upregulated in the DCM patient group, while the expression of BIRC3 and CAMK2A was downregulated (Fig. 5A). This evidence concerns the gene CAPN1 and familial dilated cardiomyopathy.
