Umbilical glucose and umbilical sclerostin concentrations did not differ between pregnant women with and without GDM (for glucose: 75.00 ± 29.33 mg/dL vs 59.71 ± 9.32, respectively, P = .092; for umbilical sclerostin: 9.02 ± 14.03 pmol/L and 11.90 ± 15.87 pmol/L, respectively, P = .611). Here, SOST is linked to gestational diabetes.
