Abstract
Autosomal recessive polycystic kidney disease (ARPKD) is a rare genetic fibrocystic disorder of kidneys and liver, primarily caused by biallelic variants in the PKHD1 gene.1 Variants in multiple genes can result in ARPKD-mimicking phenocopies, including genes causing autosomal dominant polycystic kidney disease (ADPKD), HNF1B-nephropathy, or nephronophthisis.2 Clinical differentiation between ARPKD and ARPKD-mimicking phenocopies like severe very early-onset forms of ADPKD, HNF1B-related cystic kidney disease, or nephronophthisis may be difficult.
