Polycystic kidney disease (BTPKD) is a hereditary disease which can be tested with a DNA test. Polycystic Kidney Disease (PKD) in Bull Terrier is an inherited autosomal dominant disease. The mutation in PKD1 gene causes dogs to develop kidney cysts filled with fluid. These cysts grow in size and number as the diseases progresses, gradually replacing healthy kidney tissue with non-functional cysts and thus impairing renal function. Chronic renal failure appears in middle to old age and leads to death. Although renal cysts can be detected by ultrasound screening, it is difficult to establish a definite diagnosis, especially early in the disease course.

Mutation: PKD1 gene

Genetic test: The method used for genetic testing is extremely accurate and allows complete differentiation between affected animals, carriers and healthy dogs. DNA testing can be done at any age.

DNA test sample: EDTA whole blood (1.0 ml) or buccal swabs. Detailed information about sampling can be found here.
