MMP1 and preeclampsia: Interestingly, our univariate analysis comparing the male and female children of the study and control groups found almost a five times greater likelihood of preeclampsia in the mother of female fetuses whose MMP1 genotype is 1G/1G (OR = 4.58, 95% CI 1.43–14.67; p < 0.02): these female children may have a higher tendency to develop preeclampsia if they later become pregnant.
