No statistically relevant difference was found in the comparison of GDM placentas with normal placentas of male fetuses (median IRS 7.0 vs. 4.0; p = 0.461, Figure 1), the comparison of placentas from female fetuses showed a significant higher expression of IL-7 in the GDM group (median IRS 8.0 vs. 6.0; p = 0.028, Figure 1). This evidence concerns the gene IARS1 and gestational diabetes.
