Distinguishing between clear, carrier and affected dogs
Clear dogs have no copies of the mutant gene responsible for the condition and will neither develop the condition nor pass the gene on to their offspring.
Carrier dogs have one copy of the normal gene and one copy of the mutant gene; they will not develop the condition, but will pass a mutant gene on to approximately half of their offspring.
Affected dogs have two copies of the mutant gene that causes the condition and will develop the disease.
Acceptance of results for this test by the Kennel Club is conditional upon the following test protocols:
- That dogs to be tested are microchipped and registered before the test sample is taken;
- That the test sample (whether buccal swab or blood sample or other) is taken by a veterinary surgeon or veterinary nurse who first confirms the microchip identity of the test subject and records both the microchip number and registration name on the sample container/package;
- That the sample is sent directly by the veterinary surgery to the testing laboratory; and
- That the testing laboratory is one which is approved by, or acceptable to, the Kennel Club.
