De novo heterozygous ADNP variants have been associated with a complex neurological phenotype characterized primarily by neurodevelopmental delay. Cardiac and renal anomalies have additionally been observed in a few patients. All reported cases to date have been ascertained postnatally. Congenital diaphragmatic hernia (CDH) has been previously observed in one child diagnosed with a de novo ADNP-related neurodevelopmental disorder. We report a fetus who presented with syndromic CDH associated with a de novo heterozygous ADNP variant.
Keywords: ADNP gene; congenital diaphragmatic hernia; de novo.
