Abstract

Congenital renal cystic dysplasia is a rare disease that occurs in approximately 1 in 4000 children and is often discovered in the antenatal period by ultrasound. It is commonly associated with oligohydramnios in utero and/or renal insufficiency or failure in the postnatal period. Aquaporins are membrane proteins that serve as transport channels in the transfer of water or small solutes across cell membranes. They play a role in the development of renal cysts. Aquaporin 11 (AQP11) deficient mice develop polycystic kidney disease in utero due to disruption of polycystin-1. Here we describe a case of bilateral cystic kidney disease in a patient with novel compound heterozygous variants in AQP11: c.780G>T (p. Trp260Cys) and c.472C>T (p.Pro158Ser) (NM_173039.2) identified by whole genome sequencing. These findings suggest, for the first time, the potential role of AQP11 in congenital renal cystic dysplasia.
