GNRH1 and systemic lupus erythematosus: The KEGG pathway analysis illustrated that the MAPK, GnRH, and inositol phosphate metabolism signaling pathways exhibited a positive link to the elevated expression of TTC7B. In contrast, the three inversely linked categories were systemic lupus erythematosus, ECM receptor interaction, and cytokine-cytokine receptor interaction (Figure 7(c)).
