On the other hand, the placental mRNA vaspin levels were similar for the GDM and non-GDM cohorts (0.6 ± 0.3 and 0.7 ± 0.3, respectively), whereas for GDM mothers, mRNA vaspin expression negatively correlated with the newborns’ birth weight (r = –0.5). The gene discussed is SERPINA12; the disease is gestational diabetes.
