PKD1 and autosomal dominant polycystic kidney disease: Reportedly, approximately 80% of patients with ADPKD harbor PKD1 mutations, 15% harbor PKD2 mutations, and the remaining 5–10% are genetically unresolved or rare mutations in other genes, such as hepatocyte nuclear factor 1β (HNF1B) and neutral α-glucosidase AB (GANAB) [5].
