Autosomal recessive polycystic kidney disease (ARPKD) is a rare genetic disorder occurring in approximately 1 in 20,000 children. It affects boys and girls equally and can cause death in the first month of life. If a child with ARPKD survives the newborn period, the chances of survival are good. For these children, approximately one-third will need dialysis or transplantation by the age of 10. Learn basic facts about what ARPKD is, how it impacts people and how the PKD Foundation helps.
