While DNAJB11 is a known disease-causing gene of ADPKD [25], and kidney cysts can develop in patients who are heterozygous for a pathogenic variant in PKHD1, more evidence is required to determine whether heterozygous NEK8 and WDR19 pathogenic variants can mimic the ADPKD phenotype. The gene discussed is WDR19; the disease is autosomal dominant polycystic kidney disease.
