TSPAN14 and gestational diabetes: Interestingly, SAT TSPAN14 expression was also negatively associated with GDM (23.2% decreased expression in O-GDM compared to O-BP), and at the same time positively associated with maternal pre-pregnancy BMI (p ≤ 0.01), with the offspring presenting 2.6% higher expression per kg/m2 increase in BMI (Table 2), corresponding to 20.6% higher levels in expression if the mother had a BMI above 25 kg/m2.
