In GDM and NGT combined, IL6 transcript was significantly and positively correlated with blood glucose measures, both at fasting (r = 0.42, p = 0.0010) and at 2 h OGTT (r = 0.39, p = 0.0022), whereas RELA transcript negatively correlated with HbA1C (r = −0.43, p = 0.0007). This evidence concerns the gene RELA and gestational diabetes.
