BACKGROUND: Pulmonary hypoplasia resulting from oligohydramnios or anhydramnios can cause severe respiratory compromise in newborn patients. We report a case of recurrent oligohydramnios in a mother with an ErbB4 mutation and speculate that the effects on the placenta through decreased vascularization contributed to oligohdyramnios and subsequent pulmonary hypoplasia in the newborn.
CASE: The pregnant mother in this case had two subsequent term pregnancies complicated by severe oligohydramnios. Both pregnancies resulted in live born female neonates with pulmonary hypoplasia, pneumothoraces, and pulmonary hypertension. The mother and second newborn, who died, were found to have the ErbB4 mutation. Examination of the placenta with that pregnancy showed decreased vascularity.
CONCLUSION: ErbB4 may have important effects on placental development and hydramnios that also may affect neonatal pulmonary hypoplasia.
