Prenatal diagnosis of an 8p23.1 deletion in a fetus with a diaphragmatic hernia and review of the literature.

Abstract

The prenatal diagnosis of an 8p23.1 deletion is reported. The diagnosis was ascertained at 22 weeks of gestation because of the discovery of a diaphragmatic hernia at ultrasound. Following cytogenetic studies and counselling, the pregnancy was terminated. An autopsy confirmed the presence of a diaphragmatic hernia and revealed also the existence of an atrio-ventricular canal (AVC) and an atrial septal defect (ASD). The clinical features of this antenatally diagnosed case are compared with those observed in 16 previously reported cases with an identical deletion of the short arm of chromosome 8. This suggests that a deletion 8p23.1 should be considered whenever a diaphragmatic hernia and/or an AVC is detected on ultrasound.
