KEGG pathway analysis showed that the pathogenic genes in SLE-related DCM are closely associated with pathways such as “Complement and coagulation cascades,” “Viral protein interaction with cytokine and cytokine receptor,” “TNF signaling pathway,” “Cytokine-cytokine receptor interaction,” and “Chemokine signaling pathway” (Supplementary Figure 1E). Here, TNF is linked to familial dilated cardiomyopathy.
