Clinical context

Polycystic kidney disease includes autosomal dominant and autosomal recessive forms, with the dominant type being the most common inherited cause of end-stage kidney disease worldwide. 2

A diagnosis of autosomal dominant polycystic kidney disease is usually made by combining a positive family history with imaging and clinical findings like hypertension or renal failure. 2
