The Kennel Club has approved a new official DNA testing scheme for von Willebrand’s disease type 1 (vWD1) in the Papillon, in order to combat the inherited disease. Variants at several genes have been shown to be associated with von Willebrand’s disease, with vWD1 being the most common.

In order to be affected, the dog must have two copies of the defective gene; if only one copy of the defective gene is inherited from either parents, the dog may be healthy but still a carrier.

“Von Willebrand’s disease is characterised by a reduced level of an important protein involved in blood clotting,” the Kennel Club says. “The severity of clinical signs is variable, but commonly includes bleeding from the nose or gums, bruising and prolonged clotting time, with implications for surgical procedures.”

Each tested Papillon will be recorded on the Kennel Club systems either as clear, with no copies of the defective gene; carrier, with the ability to pass on the gene; or affected, with clinical signs of the disorder as well as the ability to pass on the defective gene.

You can find which laboratories the Kennel Club is able to record results from here. Test results will be added to the dog’s registration details, and the results will be published in the next available Breed Records Supplement.

The Kennel Club adds, “The result will appear on any new registration certificate issued for the dog and on the registration certificates of any future progeny of the dog, and also on the Health Test Results Finder on the Kennel Club website.”
