โฆ Synopsis
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.

A subtle terminal deletion of the short arm of chromosome 8 with a breakpoint in p23.1 was detected in amniocytes. Parental chromosome studies revealed a similar deletion in the father. The fetus did not have any abnormalities in a level II ultrasound. The pregnancy was continued and resulted in the
We report the prenatal diagnosis at 30 weeks of gestation of a del(8)(p21.3-->pter) in a growth-retarded fetus with an unbalanced atrioventricular septal defect (AVSD) and a hypoplastic right ventricle. This observation further confirms the association of AVSD with terminal deletions of chromosome 8
