Autosomal recessive polycystic kidney disease (ARPKD)
is a genetic condition that is characterized by the growth of cysts in the kidneys (which lead to kidney failure) and liver and problems in other organs, such as the blood vessels in the brain and heart. The severity varies from person to person. The signs of ARPKD frequently begin before birth, so it is often called Òinfantile PKDÓ but some people do not develop symptoms until later in childhood or even adulthood. Children born with ARPKD often, but not always, develop kidney failure before reaching adulthood; babies with the worst cases die hours or days after birth due to respiratory difficulties or respiratory failure. Liver scarring occurs in all patients. The condition is caused by a mutation in the PKHD1 gene and is inherited in an autosomal recessive manner. Some symptoms of the condition may be controlled by medicines, antibiotics, healthy diet, and growth hormones.
