Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a group of inherited conditions that affect the tubules of the kidneys, causing the kidneys to gradually lose their ability to work.
ADTKD; Medullary cystic kidney disease; Renin associated kidney disease; Familial juvenile hyperuricemic nephropathy; Uromodulin associated kidney disease
ADTKD is caused by mutations in certain genes. These gene problems are passed down through families (inherited) in an autosomal dominant pattern. This means the abnormal gene is needed from only one parent in order to inherit the disease. Often, many family members have the disease.
With all forms of ADTKD, as the disease progresses, the kidney tubules are damaged. These are the structures in the kidneys that allow most water in the blood to be filtered and returned to the blood.
Their abnormal genes that cause the different forms of ADTKD are:
When the cause of ADTKD is not known or a genetic test has not been done, it is called ADTKD-NOS.
Early in the disease, depending on the form of ADTKD, symptoms may include:
As the disease worsens, symptoms of kidney failure may develop, which include:
There is no cure for ADTKD. At first, treatment focuses on controlling symptoms, reducing complications, and slowing the progression of the disease. Because so much water and salt are lost, you will need to follow instructions on drinking plenty of fluids and taking salt supplements to avoid dehydration.
As the disease progresses, kidney failure develops. Treatment may involve taking medicines and diet changes, limiting foods containing phosphorus and potassium. You may need dialysis and a kidney transplant.
The age at which people with ADTKD reach end-stage kidney disease varies, depending on the form of the disease. It can be as young as in the teens or in older adulthood. Lifelong treatment may control the symptoms of chronic kidney disease.
ADTKD may lead to the following health problems:
Call for an appointment with your provider if you have any symptoms of urinary or kidney problems.
Medullary cystic kidney disease is an inherited disorder. It may not be preventable.
