Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. ADPKD is a progressive disease and symptoms tend to get worse over time. The most common symptoms are kidney cysts, pain in the back and the sides and headaches. Other symptoms include liver and pancreatic cysts, urinary tract infections, abnormal heart valves, high blood pressure, kidney stones, and brain aneurysms. ADPKD is most often caused by changes in the PKD1 and PKD2 genes, and less often by changes in the GANAB and DNAJB11 genes. It is inherited in a dominant pattern. ADPKD is the most common inherited disorder of the kidneys.
