When S100B levels were compared between the studied groups higher (p < 0.01, for all) protein levels were observed in GDM than controls at T1, T2 (24–32 GA), and T4 (>37 GA), whilst no differences (p > 0.05) at T3 (33–37 GA) were found (Figure 2). The gene discussed is S100B; the disease is gestational diabetes.
