SLC2A4 and gestational diabetes: However, we noticed significant positive associations of the IRS2 transcript with pregnancy weight (rho = 0.46; p = 0.013), FPG (rho = 0.42; p = 0.023), FI (rho = 0.44; p = 0.018), and HOMA-IR (rho = 0.48; p = 0.008) in the GDM group, and an inverse correlation of the SLC2A4 transcript with HOMA-IR (rho = −0.48; p = 0.007) in the pGDM group.
