KLF14 and polycystic ovary syndrome: The genotype distribution of KLF14, miR-27a, and miR-196a-2 between PCOS patients and healthy controls were strongly associated with the risk and susceptibility to PCOS, as indicated by statistical significance (p < 0.05), except for miR-423 genotypes, which were not found to be associated with PCOS (p > 0.05).
