Embryology of neural tube defects: information provided by associated malformations.

abstract：OBJECTIVE:To determine the underlying molecular aetiology in a non-consanguineous Irish family who have had three fetal losses because of a primary myopathy characterised by fetal akinesia, arthrogryposis multiplex, bilateral pulmonary hypoplasia and reduced muscle bulk. METHODS:Fetal DNA extracted from amniotic cells...
