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. Here, WDR19 is linked to Complex Cyst of Kidney.
