Introduction: Autosomal recessive renal tubular dysgenesis (ARRTD) is a rare disorder of renal tubular development. ARRTD is a severe condition with high risk of fetal demise and early neonatal death with only limited case reports of survival over two years [1]. Prenatal diagnosis of ARRTD is challenging and diagnosis has only previously been confirmed after postnatal or post-mortem investigation. Case: To the best of our knowledge, we describe the first reported case of utilising targeted genetic testing on the chorionic villous sample (CVS) to identify a homozygous variant in the angiotensinogen (AGT) gene. Discussion: By substantiating the diagnosis of ARRTD prenatally we allow timely and appropriate counselling during pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
