Fast facts about ADPKD

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common genetic renal disorder. In the UK, it accounts for around 1 in 10 people on dialysis and 1 in 8 with a kidney transplant.

ADPKD affects between 1 in 400 and 1 in 1000 people worldwide. It occurs equally in both men and women, across all ethnic groups.

ADPKD is caused by mutations in one or more genes causing them to function abnormally. Because ADPKD has a 'dominant' inheritance pattern, there is 1 in 2 chance that an affected parent will pass on ADPKD to each child born.

What are polycystic kidneys

Polycystic vs Normal KindeyADPKD is characterised by numerous fluid-filled cysts in the kidneys and often the liver and pancreas. Over time, the cysts grow and multiply, replacing normal healthy tissue and causing the kidneys to lose their function. Kidneys can enlarge to 3 to 4 times their normal size.

Problems in ADPKD

In early stages, there may be no symptoms and sometimes the cysts may not be noticed until adulthood or through family screening. However, some children present early with symptoms which can be confused with another form of PKD called AR (or autosomal recessive) PKD.

Common symptoms will vary by individual and may include back or abdominal pain, recurrent urinary infections or blood in the urine, kidney stones and kidney failure.

Nearly two thirds of adults and one third of children with ADPKD will develop high blood pressure or hypertension. Early and effective treatment of hypertension is essential to minimise the risks of strokes or heart problems.

Around 1 in 12 people with ADPKD will develop small brain aneurysms. These tend to occur in individuals with a family history of strokes.

Many people with ADPKD will also get PLD or polycystic liver disease. Usually, the liver is not affected by the cysts but they can grow uncomfortably large and cause pain.

However, not everyone with ADPKD will develop kidney failure and some people may never have any problems or be unaware they have the condition.

The future for those affected by ADPKD

ADPKD is at present incurable. There is no treatment that will stop the cysts developing and growing. The primary focus is on managing the symptoms.

However, a number of drugs are currently being trialled around the world aimed at slowing the decline of kidney function, giving future hope of an improved quality of life for those affected and their children.
