Breeds Affected: Bull Terrier, Miniature Bull Terrier
Samples Accepted: Blood, Buccal Swabs
Disease Information: Polycystic Kidney Disease (PKD) is characterized by the development of cysts in the kidney, eventually leading to chronic renal failure in middle-age to old animals.
Inheritance Information: PKD is autosomal dominant, meaning that animals with just one copy of this allele will be affected. 50% of their offspring will also be affected.
The possible genotypes are:
n/n The dog is normal, and cannot produce affected offspring.
n/PKD The dog is affected, and 50% of the offspring will be affected.
PKD/PKD The dog is affected, and 100% of the offspring will also be affected.
– Affected animals (n/PKD, PKD/PKD) should not be used for breeding.
Test Information: This mutation test identifies a single base pair change in exon 29 of the PKD1 gene.
