They found that 161 patients (68.5%) had possible pathogenic variants in the PKD1 or PKD2, and 2 patients (0.9%) presented with truncation variants of IFT140. In contrast, our study only performed a comprehensive genetic analysis for adult patients with polycystic kidneys whose parents did not have evident polycystic kidneys. The gene discussed is PKD1; the disease is polycystic kidney disease.
