PLOD1 and familial hyperaldosteronism: In the ceRNA network, no genes were regulated by circRNA–miRNA pairs in the FL vs. FH group; 105 genes were regulated by circ_0009933–miR-15a-5p pairs in the LL vs. LH group; 811 genes were regulated by six circRNA–miRNA pairs (circ_0001504–miR-145-5p, circ_0000342–miR-181b-5p, circ_0009933–miR-15a-5p, circ_0014427–miR-23b-5p, circ_0022452–miR-363-5p, circ_0021923–miR-204-3p) in the LH vs. FH group; and 296 genes were potentially regulated by circ_0022452–miR-363-5p and circ_0001504–miR-145-5p pairs in the LL vs. FL group.
