TFF2 and familial hyperaldosteronism: The genes co-expressed with OLR1 in the FH group were enriched for intracellular protein-coding complex, transferase complex, and nuclear body (FDR < 0.05) (Table S8A), while those co-expressed with TFF2 were enriched for the apoptotic process, interleukin production, and cytokine-mediated signaling pathways (Table S8B).
