This test is part of the Official UK Kennel Club DNA Testing Scheme in Great Dane, and Labrador Retriever.
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 |
|
Clinical features of hereditary myopathy in Labrador Retrievers include hypotonia, generalized muscle weakness, abnormal postures, stiff hopping gait, exercise intolerance and increased collapse when exposed to cold.

Description |
|
This is a mutation-based gene test, which offers many advantages over other methods
The genetic defect leading to the disease has been identified. By DNA testing, the responsible mutation can be shown directly. This method provides a very high accuracy test and can be done at any age. It offers the possibility to distinguish not only between affected and clear dogs, but also to identify clinically healthy carriers. This is an essential information for controlling the disease in the breed, as carriers are able to spread the disease in the population, but can not be identified by means of common laboratory diagnostic.
IN Great Dane, the disease is caused by a different mutation and is known as Inherited Myopathy of Great Danes (IMGD)

Trait of Inheritance |
|
Hereditary myopathy in Labrador Retrievers 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 Hereditary Myopathy / Centronuclear Myopathy (HMLR, CNM / IMGD). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.
Carrier
Genotype: N / CNM [ 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 Hereditary Myopathy / Centronuclear Myopathy (HMLR, CNM / IMGD) 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: CNM / CNM [ 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 Hereditary Myopathy / Centronuclear Myopathy (HMLR, CNM / IMGD) and will pass the mutant gene to its entire offspring
