Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. These cysts can lead to kidney enlargement, reduced kidney function, and in some cases, kidney failure. PKD can be categorized into two main types: autosomal dominant polycystic kidney disease (ADPKD) and autosomal recessive polycystic kidney disease (ARPKD). ADPKD is the most common form of PKD and typically presents in adulthood, while ARPKD is a rarer form that is usually diagnosed in infancy or early childhood. Research in the field of PKD focuses on understanding the underlying genetic causes of the disease, as well as developing treatments to slow the progression of kidney damage and improve quality of life for affected individuals.
