Polycystic kidney disease (PKD)


Feline polycystic kidney disease is an inherited disease in Persian and Persian related cats. Approximately 38 % of Persian cats world-wide are positive for PKD, which is 6% of cats in total, making it the most prominent inherited feline disease. PKD causes the formation of hepatic and renal cysts as well as of fluid-filled renal cysts, often leading to renal failure.
Cystic kidneys can sporadically occur in any population of cats, but early onset and bilateral presentation is a hallmark to the hereditary form. The kidney cysts for PKD are present early, generally before 12 months, but renal failure generally occurs at a later time, thus it is considered a late onset renal disease. The presence of cystic kidneys can be determined by 6 to 8 months of age by ultrasonic techniques and affection diagnosis is generally certain by one to two years. Average age for renal dysfunction, not failure, is 7 years for cats with PKD. Thus, with out imaging techniques, cats would go undiagnosed for PKD for many years. Clinical signs are non specific but common to cats experiencing renal dysfunction, including depression, anorexia, reduced appetite, polyuria, polydypsia, and weight loss.

Trait of inheritance


Test duration

3-5 days after arrival of the sample in the lab


The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. (Buccal swab order-form). If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer.
Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
