Autosomal Dominant Polycystic Kidney: Epidemiology

Epidemiology: Autosomal dominant polycystic kidney disease (ADPKD) is a common cystic kidney disease and the most common hereditary kidney disease. It occurs in 1 to 2 per 1000 live births. It is one of the leading causes of renal failure and accounts for 5% to 10% of patients on dialysis or renal transplantation list. Most patients are between 40-50 yrs. of age at presentation. It is inherited as an autosomal dominant disorder with complete penetrance (by age 80 years). About 25% of patients have no family history and represent new mutations. There is no sex or racial predilection. This specimen photograph shows external and cut surface of a kidney that is completely replaced by numerous cysts.
