In our previous study (9), which examined the level of fatty acid-binding protein 4 (FABP4) and the level of intestinal fatty acid-binding protein (I-FABP) in pregnant women with GDM and in pregnant women belonging to the GDM risk group as controls, we showed that FABP4 and I-FABP levels were not dependent on the diagnosis of GDM, but rather on body mass index (BMI). The gene discussed is FABP2; the disease is gestational diabetes.
