However, fasting glycemia was significantly higher in women with GDM than in either insulin-treated T2D pregnant women (1.23 ± 0.05 g/L vs.0.89 ± 0.02 g/L, p = 0.001) or pregnant controls (1.23 ± 0.05 g/L vs.0.80 ± 0.03 g/L, p = 0.001) (Table 1). This evidence concerns the gene INS and type 2 diabetes mellitus.
