ABSTRACT
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 2 years [Clin Kidney J. 2012 Feb 1;5(1):56-8]. 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 utilizing 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 counseling during pregnancy.
