KEGG enrichment analysis revealed for the high-expression group: Vasopressin Regulated Water Reabsorption, Focal Adhesion, Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC), GnRH Signaling Pathway, Other Glycan Degradation, and others; for the low-expression group: Primary Immunodeficiency, Cell Cycle, Non-Homologous End Joining, and others (Figure 3D). The gene discussed is GNRH1; the disease is inborn error of immunity.
