PPARA and hydrops fetalis: The analysis revealed several pathways predominantly associated with HF, including arrhythmogenic right ventricular cardiomyopathy, regulation of lipolysis in adipocytes, PPAR signaling pathway, cGMP-PKG signaling pathway, DCM, signal transduction, regulation of cardiac muscle contraction by calcium ion signaling, cAMP signaling, cellular calcium ion homeostasis, protein phosphorylation, the oxytocin signaling pathway, negative regulation of angiogenesis, hypertrophic cardiomyopathy, protein kinase activity, and calcium ion homeostasis.
