VDR and polycystic ovary syndrome: The effects of VDR-ApaI, VDR-FokI and VDR-TaqI gene polymorphisms on hormonal, oxidative stress and clinical cutaneous manifestations parameters in cases of women with PCOS and control women were analyzed by codominant, dominant (AC + AA vs. CC for VDR-ApaI, CT+CC vs. TT for VDR-FokI, CT+TT vs. TT for VDR-TaqI), recessive (AA vs. CC+AC for VDR-ApaI, CC vs. CT+TT for VDR-FokI, TT vs. CT+CC for VDR-TaqI) and allelic genetic models.
