Ranjzad et al. (5) demonstrated thatVDR TaqI CC genotype has been associated with elevatedserum levels of LH in PCOS patients (p=0.011).In this study, the CC genotype of VDR TaqI in exon9 (rs731236) was significantly higher in cases versuscontrols (p value=0.04). Here, PLOD1 is linked to polycystic ovary syndrome.
