Clinical manifestations of functional state disturbance and cardiovascular system maladaptation after prenatal hypoxia directly correlated with signs of endothelial dysfunction (changes in endothelin-1, nitric oxide (NO), vascular endothelial growth factor (VEGF) production, circulating desquamated endotheliocytes) both in newborns and at older ages [6,7,8]. The gene discussed is VEGFA; the disease is endothelial dysfunction.
