Enriched KEGG pathways of hub genes were related to SNARE interactions in vesicular transport, cardiomyopathy, pancreatic secretion, microRNAs in cancer, transcriptional misregulation in cancer, thyroid hormone signaling pathway, calcium signaling pathway, cGMP-PKG signaling pathway, and cAMP signaling pathway. The gene discussed is TG; the disease is cardiomyopathy.
