Abstract

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common hereditary forms of chronic kidney disease. Mutations within PKD1 or PKD2 lead to innumerable fluid-filled cysts in the kidneys and in some instances, end-stage renal disease (ESRD). Affected individuals have a 50% chance of passing the mutation to each of their offspring. Assisted reproductive technology using preimplantation genetic diagnosis (PGD) allows these individuals to reduce this risk to 1% to 2%. We assess the disease burden of 8 individuals with ADPKD who have undergone genetic testing in preparation for PGD. Clinical features that predict high risk for progression to ESRD in patients with ADPKD include genotype, early onset of hypertension, a urologic event before age 35 years, and a large height-adjusted total kidney volume. Patients may have a family history of intracranial aneurysms or complications involving hepatic cysts, which may further influence the decision to pursue PGD. We also explore the cost, risks, and benefits of using PGD. All patients with ADPKD of childbearing potential, regardless of risk for progression to ESRD or risk for a significant disease burden, will likely benefit from genetic counseling.
