Is there a difference between autosomal dominant and autosomal recessive polycystic kidney disease?

Yes: The dominant form occurs mostly in adults. It is inherited but it takes time to show up as a diagnosable disease in middle to later age. Depending on your luck you either have it from your parent or not( 50% chance).The recessive form could be carried by seemingly healthy persons and when manifests as a disease in the offspring, it shows up at a much earlier age.
