We demonstrated that the high-risk group was significantly enriched in the top 13 biological pathways, including “Regulation of actin cytoskeleton”, “Focal adhesion”, “Vasopressin regulated water reabsorption”, “Dilated cardiomyopathy”, “Glycosaminoglycan biosynthesis chondroitin sulfate”, “Calcium signaling pathway”, “Notch signaling pathway”, “ECM receptor interaction”, “Phosphatidylinositol signaling system”, “MAPK signaling pathway”, ”Hypertrophic cardiomyopathy”, “Vascular smooth muscle contraction”, “FcγR-Mediated Phagocytosis” (Supplementary Materials Figure S1). The gene discussed is FCGR2A; the disease is dilated cardiomyopathy.
