Polycystic Kidney Disease
What is Polycystic Kidney Disease?
Polycystic kidney diseases (PKD) are a group of disorders characterized by dilated segments of renal tubules that pinch off to form fluid-filled structures or cysts. As cysts gradually enlarge, they compress normal kidney tissue and prevent it from functioning normally.
This can result in high blood pressure and kidney failure, which may require dialysis or transplantation. As kidney cysts enlarge, they also can cause a number of other problems including pain, infection and hemorrhage. Kidney stones are also more common in individuals with cystic kidney disease.
One form of PKD, called autosomal dominant polycystic kidney disease (ADPKD), is the most common single-gene disorder that causes kidney failure. It is estimated that approximately 600,000 individuals in the United States alone have ADPKD. ADPKD is the fourth-most common cause of kidney failure in the U.S. and occurs in people of all races and ethnicities.
Genetics of Kidney Diseases
A number of acquired and genetic diseases can result in polycystic kidneys. The various forms differ with respect to the way in which they are inherited (autosomal dominant, autosomal recessive or X-linked); the range of renal and extra-renal manifestations that accompany the cystic disease; the age at which renal failure most commonly presents (childhood vs. adult); and the mutant gene responsible for causing the disorder.
Some of the disorders associated with kidney cysts and/or liver cysts:
Autosomal Dominant Polycystic Kidney Disease (ADPKD)
Individuals with one mutant copy of the gene (PKD1 or PKD2) develop the disease. A parent with the disease has a 50 percent chance of passing the mutant gene to his/her children. ADPKD is associated with slowly progressive cystic kidney disease that results in kidney failure in about 50 percent of affected individuals. The age at onset of kidney failure is variable and 50 percent of individuals with ADPKD develop kidney failure by age 60. Hypertension, cerebral aneurysms, cardiac valvular abnormalities, liver cysts, kidney stones, and aortic aneurysms are important complications.
Autosomal Dominant Polycystic Liver Disease (PLD)
This is an autosomal dominant disorder that is biologically related to ADPKD. Several genes are known to cause PLD (for example, Sec 63, PRKCSH, ALG8, ALG9 and Ganab), but there are others that have not yet been identified. Individuals with PLD develop liver cysts and may have a small number of kidney cysts, but typically don’t develop kidney failure.
Autosomal Recessive Polycystic Kidney Disease (ARPKD; also called PKHD1)
This is a relatively rare disorder occurring in 1 in 20,000 individuals. The disease results when both copies of the fibrocystin gene on chromosome 6 are mutated. Parents are carriers and unaffected. Affected offspring inherit a mutant copy from each parent. A couple in which both partners are carriers for the disease have a 25 percent chance of having a child with the disease. The disease usually presents during infancy or in childhood, with up to 50 percent of affected children dying in the first year of life. Older children and adults may have severe liver disease requiring transplantation.
This is a collection of recessive diseases in which parents are unaffected carriers and offspring develop kidney disease between infancy and adolescence. Some forms of the disease are associated with eye abnormalities.
This is a group of recessive disorders that present with eye disease (retinopathy), obesity, hypogonadism, a variety of kidney abnormalities, extra digits on the hand or feet, and mental retardation.
Medullary Cystic Disease
This is an autosomal dominant disease caused by mutations in the gene for uromodulin on chromosome 16. Mutations in the mucin gene on chromosome 1 were also shown to be associated with medullary cystic disease. Although individuals do have some kidney cysts, interstitial scarring of the kidneys is prominent and kidneys tend to be small. Recently, another gene, DNAJB11, was also shown to cause kidney cysts with interstitial scarring. Renal failure typically develops in adulthood; other complications include high uric acid levels and gout.
Tuberous sclerosis (TSC) is an autosomal dominant disease that is caused by mutations in genes called TSC1 or TSC2. Tuberous sclerosis is associated with benign tumors in multiple organs. Kidney cancer is a rare complication of TSC. Individuals with TSC may have a few renal cysts but a subset can present with polycystic kidney disease resembling ADPKD. This may be caused by mutations that affect both genes.
Von Hippel Lindau Syndrome
This is an autosomal dominant disorder that presents with tumors in the nervous system, adrenal gland tissue, kidney cancer and kidney cysts.
Is There a Treatment for PKD?
In April 2018, the FDA approved a new drug called Tolvaptan, or Jynarque, for the treatment of ADPKD. Tolvaptan is a V2R antagonist that blocks vasopressin signaling, a key driver of cyst growth in ADPKD due to the resulting intracellular increase in cyclic adenosine monophosphate.
There are other experimental drugs being tested in mouse models of PKD and some in clinical trials. In addition, healthcare providers continue to manage complications of the various forms of the disease, such as treating hypertension or infections.
Drs. Terry Watnick, Stephen Seliger, Valeriu Cebotaru and Songul Onder staff the University of Maryland Inherited Renal Disease Clinic. The clinic forms the translational arm of the PKD group at the University of Maryland and receives national and international referrals of patients who require diagnosis and/or management of complicated cystic kidney disease. Dr. Stephen Seliger directs the Clinical Research Program, which is involved in numerous clinical trials.
The team at the University of Maryland provides multidisciplinary expertise in many subspecialty fields involved in treating ADPKD complications, including Gastroenterology and Hepatology, Neurosurgery, and Interventional Radiology
The University of Maryland Comprehensive Transplant Program performs around 250 kidney transplants per year and is the largest program in Maryland.

PKD poses special challenges for investigators seeking therapies.
Polycystic kidney disease is frequently a progressive disease that evolves over decades. The risk of a therapy must be less than the potential benefit. The University of Maryland team and collaborators are tackling the problem on two parallel tracks. In the first, the investigators seek to define the pathophysiology of the disease as a means of identifying steps for possible intervention. The second approach is aimed at determining the normal functions of the PKD proteins, seeking to identify ways that their activity may be replaced in disease tissue.
Although we have made significant progress since the first human PKD gene was discovered, significant questions remain. We still do not know why some patients develop severe disease or aneurysms while family members with the same mutation do not. Are there other underlying genetic factors that determine the severity of disease or its rate of progression? Why do some mutations result in severe disease more frequently? How does loss of PKD proteins cause the vascular manifestations that are observed? How do dietary or lifestyle factors affect progression of disease? Do any of the experimental therapies used in other forms of mouse PKD work in the form that most commonly affects humans? Future NIH clinical studies propose to use changes in the amount of kidney tissue as a means of assessing response to therapy. Is this really a suitable surrogate marker for functional response?
- Maryland Polycystic Kidney Disease Research and Translation Core Center (MPKD-RTCC): The University of Maryland is home to one of three NIH-sponsored PKD Research and Translation Core Centers. The Center is comprised of four biomedical Cores that are charged with developing and distributing state-of-the-art research reagents to a national and international group of PKD researchers. The goal of the Center is to foster a greater understanding of the fundamental aspects of PKD biology.
- Identify PKD signaling pathways: Most PKD genes encode proteins that sit on the surface of cells and transmit information across the cell boundary into the cell interior. The cell uses this information to respond to its environment. In PKD, the cell is either unable to acquire this information because the sensor is defective or is unable to respond properly to the signal. University of Maryland researchers are seeking to define the types of information that PKD proteins sense and the pathways inside the cell that PKD proteins regulate.
- Characterize the cellular biology of PKD proteins: Many PKD proteins are found in primary cilia, a small hair-like structure on the surface of the cell that is required for proper cell function. Polycystic kidney disease results when cilia aren’t properly formed or when signaling proteins don’t make it to the primary cilia. University of Maryland Investigators are using a variety of tools to study how PKD proteins reach the cilia in kidney cells. One of our investigators has found that a biochemical reaction that cuts the PKD1 protein is required for PKD1 and PKD2 to reach the cilia.
- Determine how PKD proteins help to preserve normal blood vessel structure and function: The cardiovascular complications of PKD are an important cause of premature death and morbidity, especially brain aneurysms that can occur in a sub-group of patients with ADPKD. Studies of patients with ADPKD and of mouse models of human ADPKD show that PKD proteins are essential for normal blood vessels. University of Maryland nephrology investigators are seeking to understand the genetic factors that predispose certain patients to develop aneurysms and to define the signaling pathway that may be altered in ADPKD blood vessels. The proposed studies aim to understand this process in the hope that future screening strategies and treatments may be directed at preventing these complications.
- Engineer and manipulate mouse models of human PKD: The University of Maryland team has used transgenic technologies to produce mice with cystic kidney disease very similar to the disorder that affects humans (both ADPKD and ARPKD). These powerful models can be used to test various therapies for PKD in a cost-effective manner before they are tested in humans.
- Determine the function of the ARPKD protein (called fibrocystin or polyductin): The University of Maryland team has recently developed animal and cell culture systems that can be used to model the human disease and the ARPKD protein’s function. Preliminary studies at University of Maryland suggest that fibrocystin and the polycystins may work together as a complex to ensure proper formation of the kidney tubule.
- Use simple systems to study PKD proteins: We have developed a fruit fly with mutations in the PKD2 gene. University of Maryland investigators are using this simple system to examine how PKD proteins reach the tip of the cilium.
- Longitudinal cohort study: Progression of autosomal dominant polycystic kidney disease to kidney failure is highly variable. A number of factors including age, genotype and incidence of cardiovascular disease determine how quickly the disorder progresses. Dr. Stephen Seliger, who directs the Clinical and Translation Core for the MPKD-RTCC, is collecting baseline data on a large cohort of individuals with ADPKD. The goal of the cohort study is to better understand the factors that influence PKD progression. In addition, this study will establish a high-quality biorepository with specimens collected under standardized conditions. This biorepository has been a valuable resource for PKD investigators.
