MMP1 and preeclampsia: Our findings do not confirm those of Jurajda et al. [33], who did not find any significant association between 1G/2G MMP1 gene polymorphisms and pregnancy hypertension in a Caucasian population; however, the study of Jurajda et al. included women with recognized preeclampsia, eclampsia, and chronic hypertension, while patients with chronic hypertension were excluded in the present study.
