Also, the level of vasoinhibins in amniotic fluid from patients with preeclampsia is inversely correlated with birth weight, that is, higher vasoinhibin level in the amniotic fluid associates with lower birth weight (47), and vasoinhibins antagonize the proangiogenic actions of VEGF in amniotic fluid from patients with preeclampsia (47). The gene discussed is VEGFA; the disease is preeclampsia.
