On the other hand, the leptin concentration in cord plasma was slightly higher in both obese cohorts regardless of GDM occurrence (with GDM: 6.8 ng/mL and without GDM: 7.6 ng/mL, respectively) in comparison to the cord plasma level of the control cohort (5.9 ng/mL) [118]. The gene discussed is LEP; the disease is gestational diabetes.
