This listing covers four different tests , however, we will perform one test only depending on the breed.

Rhodesian Ridgeback

Early Onset Adult Deafness (EOAD)

Rottweiler

Early-onset Canine Nonsyndromic Hearing Loss

Bauceron

Nons-Syndromic deafness

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.

We also offer Deafness with Vestibular Dysfunction (DVD), aka DINGS 1 & 2 in Doberman

Please note that Exon 2 can be found in all dog breeds, there is another DM mutation in Exon 1 which can only be found in Bernese Mountain Dog, click here for more information.

For bernese Mountain Dog we have a special offer for both Exon 1 and Exon 2 at reduced price, click here for more details.

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)

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
• Yorkshire Terrier

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.

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.

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).

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.
