This test is part of the Official UK Kennel Club DNA Testing Scheme in Irish Setter (Red Setter).
for UK registered dogs, Laboklin can send results of the tests which are part of the Official UK Kennel Club DNA testing scheme to the Kennel Club (KC) to be recorded and published
as part of the Kennel Club scheme. Results will only be recorded and published by the KC if the result report includes the dog’s
microchip or tattoo number along with either the dog’s registered name or registered number. Any test results that do not carry these identifying
features will not be recorded by the Kennel Club.
In order to ensure that test results are sent to the Kennel Club, customers must also sign the declaration section on the order form to give Laboklin permission to do so.
important:
When you sign the declaration, Laboklin will send the results to the KC on your behalf, and you do not need to send them to the KC yourself again to avoid unnecessary duplications.

The Disease |
|
Canine Leukocyte Adhesion Deficiency (CLAD) is a fatal immunodeficiency disease found in Irish Setters. The condition is caused by mutation in a gene encoding a leucocyte surface molecule, leading to a dysfunction of the granulocytes. Therefore, the cell-cell adhesion events are disturbed.
Because their healing capacities are impaired, the affected dogs show severe infections of omphalophlebitis, skin infections, osteomyelitis and gingivitis. They die early in life from multiple severe infections, even if treated with massive doses of antibiotics.

Description |
|
This is a mutation-based gene test, which offers many advantages over other methods
The genetic defect leading to this disease has been identified. By DNA testing, the responsible mutation can be identified directly. This method ensures that the test result is highly accuracy and can be applied at any age. It offers the possibility to distinguish not only between affected and clear dogs, but also to identify clinically healthy carriers. This information is essential for controlling the disease within the breed, as carriers are capable of spreading the disease to next generations, while it can not be identified by means of common laboratory diagnostic.
If a particularly valuable dog turns out to be a carrier, it can be bred to a clear animal, and then the non-carrier puppies can be saved for the next round of breeding. But given the lethal nature of this disease, it is the best to select against carriers who are not superlative dogs in order to entirely eliminate the gene from the line within two or three generations

Trait of Inheritance |
|
CLAD is an inherited autosomal recessive trait. This means that a dog can be clear (homozygous normal), affected, or a carrier (heterozygous). The carriers can spread the diseased gene in the population. Therefore, reliable information on non-affected dogs is the key to controlling this disease.

Clear
Genotype: N / N [ Homozygous normal ]
The dog is noncarrier of the mutant gene.
It is very unlikely that the dog will develop CLAD (Canine Leukocyte Adhesion Deficiency). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.
Carrier
Genotype: N / CLAD [ Heterozygous ]
The dog carries one copy of the mutant gene and one
copy of the normal gene.
It is very unlikely that the dog will develop CLAD (Canine Leukocyte Adhesion Deficiency) but since it carries the mutant gene, it can pass it on to its offspring with the probability of 50%. Carriers should only be bred to clear dogs. Avoid breeding carrier to carrier because 25% of their offspring is expected to be affected (see table above)
Affected
Genotype: CLAD / CLAD [ Homozygous mutant ]
The dog carries two copies of the mutant gene and
therefore it will pass the mutant gene to its entire offspring.
The dog is likely to develop CLAD (Canine Leukocyte Adhesion Deficiency) and will pass the mutant gene to its entire offspring
