Median concentration of STC1 protein in plasma in the GDM (median 690 pg/ml, range 263–1183; ANCOVA, P = 0.026) and the PE group (median 773 pg/ml, range 332–1715; ANCOVA, P = 0.035) was significantly elevated compared to control samples (median 418 pg/ml, range 124–1125) (Figure 5A). The gene discussed is STC1; the disease is gestational diabetes.
