Autosomal recessive polycystic kidney disease.

Autosomal recessive polycystic kidney disease is a rare inherited disorder which usually becomes clinically manifest in early childhood, whereas autosomal dominant polycystic kidney disease usually is a disorder of adult onset. With increasing knowledge and improving diagnostic techniques, it becomes evident that the spectrum of both entities is much more variable than generally known. The presentation of autosomal recessive polycystic kidney disease at later ages and survival into adulthood have been reported. The diagnostic criteria, clinical course, genetics and differential diagnosis of autosomal recessive polycystic kidney disease will be presented.
