Description |
|
This listing covers four different tests , however, we will perform one test only depending on the breed.
Rhodesian Ridgeback
Early Onset Adult Deafness (EOAD)
EOAD is an inherited disease affecting the Rhodesian Ridgeback breed, it is characterised by progressive loss of hearing which starts around 4 months of age and it is usually present around the age of 1-2 years.
Rottweiler
Early-onset Canine Nonsyndromic Hearing Loss
Sensorineural hearing loss has been observed in Rottweilers. The disease is clinically and genetically similar to human LOXHD1-related hearing disorder, a DNA test is now available to help breeders in controlling this type of hearing disorder in the population.
Bauceron
Nons-Syndromic deafness
Another non-syndromic deafness affecting the Beauceron dog breed. The disease is characterised by a bilateral hearing loss in puppies and it is not linked to coat colour.
Please note that the test performed will be different depending on the breed:
if the breed is:
- in Doberman : we will perform DINGS1 (mutation in the PTPRQ gene),
- in Rhodesian Ridgfebacks, we test for the EOAD variant
- In Beauceron, we test for Nons-Syndromic Deafness in Bauceron (CDH23), and
- in Rottweilers, we test for arly-onset Canine Nonsyndromic Hearing Loss in Rottweilers.

The Disease |
|
Canine degenerative myelopathy (also known as chronic degenerative radiculomyelopathy) is a progressive disease of the spinal cord in older dogs. The disease has an insidious onset typically between 7 and 14 years of age. It begins with a loss of coordination (ataxia) in the hind limbs. As of July 15, 2008 the mutated gene responsible for DM has been found present in 43 breeds including German Shepherds, Boxers, Chesapeake Bay Retrievers, Rhodesian Ridgebacks, and both breeds of Welsh Corgis. The disease is chronic and progressive, and resulting in paralysis.
|
|
|
|
|
Clinical Signs |
|
Degenerative myelopathy initially affects the back legs and causes muscle weakness and loss, and lack of coordination. These cause a staggering effect that may appear to be arthritis. The dog may drag one or both rear paws when it walks. This dragging can cause the nails of one foot to be worn down. The condition may lead to extensive paralysis of the back legs. As the disease progresses, the animal may display symptoms such as incontinence and has considerable difficulties with both balance and walking. If allowed to progress, the animal will show front limb involvement and extensive muscle atrophy. Eventually cranial nerve or respiratory muscle involvement necessitates euthanasia.
Progression of the disease is generally slow but highly variable. The animal could be crippled within a few months, or may survive up to three years
|
|
|
| |
|
Trait of Inheritance |
|
Tow alleles are invloved in Degenerative Myelopathy, A and G, therefore a test result can be A/A, A/G, or G/G.
Mode of inheritance is autosomal recessive with variable penetrance;

Description |
|
The D locus is the primary locus associated with diluted pigment, which results in coats that would otherwise be black or brown instead showing up as gray, or blue in the case of black, and pale brown or Isabella / Lilac / Lavender in the case of brown. The melanophilin gene has recently been shown to be responsible, but not all of the dilute causing mutations have been identified yet.
A recessive mutation in the melanophilin gene was identified as the cause of colour dilution phenotypes in the dog. Two alleles (variants) are described: the dominant full colour (D) and the recessive dilute (d). Two copies of dilute are needed to lighten black pigment to blue / grey and brown (liver / chocolate / cocoa / red in border collie) pigment to lilac / isabella / lavender (in Pomeranian). A diagnostic DNA test identifies the specific variants of the MLPH gene.
Please note that in the Chow Chow, Thai Ridgeback and Sloughi breeds, there is another mutation that can cause coat colour dilution, it is the D2 Locus mutation and in those breeds both D1 Locus and D2 Locus mutations must be tested for complete analysis.
Please note that in the Chihuahua, Italian Greyhound, Mudi (Hungarian Mudi) and Hungarian Pumi breeds, there is another mutation that can cause coat colour dilution, it is the D3 Locus mutation and in those breeds both D 1Locus and D3 Locus mutations must be tested for complete analysis.
Please note that dilution (blue, lilac, isabella, etc) is just a colour and that it is not known to be associated with any health conditions
KC
Please note that this test is part of the KC DNA testing scheme in Labrador Retriever. If you would like Laboklin to send the result to the KC, please sign the declaration at the bottom of the form to give us a permission . Please note that the KC will oly publish clear results but would make a note of any result received.
Colour Dilution Alopecia (CDA)
There is no test for CDA and there is no evidence that CDA is caused by dilution
CDA is a genetic recessive inherited condition that causes patches of hair thinning or loss and may also include flaky and/or itchy skin. CDA occurs in dilute dogs (homozygous for the dilute gene d/d) in some breeds, however there is no direct link between CDA and the dilute gene, and there is no evidence that the dilute gene is responsible for CDA. It is though that there are other, not yet identified, genetic factors causing CDA in dilute dogs of some breeds. Any colour can carry CDA but symptoms are only expressed in blue and isabella dogs affected by CDA.
breeding
Since CDA is a recessive gene, it can, in theory, be bred out of most lines by breeding dilute dogs with healthy coats. Breeding healthy dilute dogs with healthy dilute dogs is one way to reduce the occurrence of CDA until testing becomes available.
Breeds known to be affected by CDA:
- Bernese Mountain Dog
- Boston Terrier
- Chihuahua
- Chow Chow
- Dachshund
- Doberman Pinscher
- Great Dane
- Irish Setter
- Italian Greyhound
- Mudi (Hungarian Mudi)
- Newfoundland
- Saluki
- Schipperke
- Shetland Sheepdog
- Standard Poodle
- Whippet

The Disease |
 |
Juvenile Myoclonic Epilepsy (JME) in Rhodesian Ridgebacks
JME is an inherited disease in the Rhodesian Ridgeback breed. Affected dogs start showing symptoms between the age of 6 weeks and 18 months. Symptoms include frequest myoclonic jerks or twiches especially when the dogs are sleeping or resting. Photo sensitivity has also been noticed in affected dogs. Most affected dogs will also develop more severe generalized and tonic clonic seizures.
Due to the recessive mode of inheritance, affected dogs must inherit two copies of the mutation, one from each parents.
The test will tell you if your dog has 0, 1 or 2 copies of the mutation. Clear (N/N) and carriers (N/ JME) are healthy dogs and will not develop the specific symptoms associated with the JME mutation, however carriers should only be bred to clear dogs to avoid having affected puppies.
Please note that there are other forms of epilepsy that cannot be eliminated by this test. |

Clear
Genotype: N / N [ Homozygous normal ]
The dog is noncarrier of the mutant gene.
It is very unlikely that the dog will develop Juvenile Myoclonic Epilepsy ( JME ). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.
Carrier
Genotype: N / JME [ 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 Juvenile Myoclonic Epilepsy ( JME ) 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: JME / JME [ Homozygous mutant ]

Description |
|
This test is for the 'bd', 'bc' and 'bs'variants, which are described in all dog breeds and are responsible for the brown coat colour, which is also known in some breeds as liver, chocolate, chestnut, sedge, and less frequently, red. Two copies of the b-allele are needed to dilute black pigment to brown. For red or yellow dogs, the brown allele does not dilute the hair colour, but will change the colour of nose and foot pads from black to brown if two brown alleles are present.
When one of the variants is found homozygous (bd/bd, bc/bc or bs/bs), dark pigment (eumelanin) is diluted to brown in the pigmented areas. However, when several variants of the B-locus are found in heterozygous state (example N/bd and N/bc), it is not always possible to directly determine the influence on the eumelanin because this depends on whether the variants are located on the same or different chromosmes, however, the dog will definitely pass the variants to its offspring.
Australian Shepherd and Lancashire Heeler Please note there are two additional rare variants, which are not analysed in this test. The 'b4' variant which is only found in few Australian Shephered lines, and the 'be' variant which is only found in Lancashire Heeler, and therefore for a complete analysis in Australian Shepherd and Lancashire Heeler, you need to order this test in addition to the rare variant test . You can take advantage of our special offer 'second coat colour test at half price (excluding bundles)'.
French Bulldog
In French Bulldog, in addition to the B-locus, the Cocoa gene is also responsible for the brown coat colour, and therefore, in addition to this test you also need to order the Cocoa coat colour test . You can of course take advantage of our special offer 'second coat colour test at half price (excluding bundles)'.

The Disease |
 |
In cooperation with Prof. Dr. Mischke (Tierärztliche Hochschule Hannover) LABOKLIN was able to identify a missense-mutation in exon 7 of the factor IX gene that is responsible for the lack of active factor IX protein in Rhodesian Ridgeback Dogs.
Haemophilia B is a sex-linked disorder (x-chromosomal recessive). Male dogs express the disease when they have one mutated x-chromosome. The mutated x-chromosome comes from the bitch. In most cases female dogs are carrier of one mutated x-chromosome without being diseased (conductor). According to Mendel's Law of Inheritance, 50% of the male puppies of a carrier bitch will have the mutated x-chromosome and express the disease and 50% of the female puppies will be healthy carriers (conductors). Female dogs will be diseased when they have two mutated x-chromosomes (one from the mother, one from the father). In that case both, father and mother must have the mutated x-chromosome (e.g. diseased male dog bred to conductor bitch). |
|
|
|
|
Description |
|
DNA test
The mutation responsible for haemophilia B can now be identified using our DNA-test. The test can be performed on dogs of any age and even puppies can be tested. The DNA test does not only differentiate healthy and diseased dogs, but furthermore identifies healthy carrier (female) dogs. This is of crucial importance for dog breeders.
To achieve a maximum reliability of the test result, we perform the DNA-test of each submitted sample in two independent test runs.

|
Trait of Inheritance |
1. Homozygous healthy:
Genotype female: N(X)/N(X),
Genotype male: N(X)/Y (homozygous healthy)
A dog like this is healthy and does not carry the mutated x-chromosome. Offspring of this dog will
not get the mutated x-chromosome.
2. Heterozygous carrier (only female):
Genotype female: N(X)/FIX(X) (heterozygous carrier)
A bitch like this carries one copy of the mutated gene. It is unlikely that the bitch will suffer from
haemophilia B, however there is a 50% chance that she will pass on the mutation to her offspring.
3. Homozygous affected:
Genotype female FIX(X)/FIX(X) (homozygous affected)
Genotype male FIX(X)/Y (hemizygous affected)
Because of the x-chromosomal mode of inheritance, a homozygous affected female dog carries
two mutated x-chromosomes and a homozygous affected male dog carries one mutated
x-chromosome. Female and male homozygous affected dogs have a high risk to express
haemophilia B. The bitch will pass on the mutation to a 100% of her offspring and 50% of
the offspring of the male dog will get the mutated x-chromosome. |
