In this study, neither these VDR genetic polymorphisms nor VDR haplotypes predisposed to preeclampsia or gestational hypertension [59].The authors concluded that other VDR polymorphisms might affect the risk of getting preeclampsia or gestational hypertension, as the VDR gene is very large (over 100,000 base pairs) [56,61]. Here, VDR is linked to preeclampsia.
