Although the impact of GDM on various GLUTs has been investigated (Stanirowski et al., 2017), the involvement of GLUT3 in GDM is underestimated because GLUT3 transports extracellular glucose at an approximately sevenfold faster rate than that observed with GLUT1 (Simpson et al., 2008). The gene discussed is SLC2A3; the disease is gestational diabetes.
