Polycystic Kidney Disease
Polycystic kidney disease (PKD) is an inherited disease that causes many cysts to form in the kidneys.
Cysts, which are sacs filled with fluid, grow in both kidneys causing them to become enlarged. The number of cysts can range from a few to a great number. The size of the cysts can vary from too small to detect, to cysts that are larger than the kidney itself.

PKD is caused by an inherited gene. Children have a 50% chance of developing PKD if one parent carries the gene. If a person has the PKD gene, he or she will have some form of the disease in his or her lifetime.
There is also a rare form of PKD, called autosomal recessive polycystic kidney disease, that affects newborns, infants, and children. This form of PKD can cause death in the first month of life.
