Houde et al. [24] analyzed the placental methylation levels of the lipoprotein lipase (LPL) enzyme, which contributes to the transfer of free fatty acids from maternal lipoproteins to the fetus, and observed that the women with GDM had lower levels of methylation in each of the 3 CpG sites evaluated in comparison to NTG women. Here, LPL is linked to gestational diabetes.
