The KEGG pathway enrichment analysis results were mostly distributed in signalling pathways such as oxytocin signalling pathway, proteoglycans in cancer, neuroactive ligand-receptor interactions, basal cell carcinoma, arrhythmogenic right ventricular cardiomyopathy, and regulation of stem cell pluripotency (Fig. 4C and D). The gene discussed is OXT; the disease is Arrhythmogenic right ventricular dysplasia.
