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
Cobalamin malabsorption (merslunf-Gräsbeck Syndrome (IGS)) refers to a genetic disorder by which the vitamin B12, also known as cobalamin, fails to be absorbed from the intestine. Lack of cobalamin leads to changes in the hematopoietic system and to neurological symptoms due to irreversible damage of the brain and nervous system. Symptoms include anorexia, lethargy and failure to gain weight. Cobalamin malabsorption can be managed by supplementation with regular doses of cobalamin.

Clear

Genotype: N / N [ Homozygous normal ]

The dog is noncarrier of the mutant gene.

It is very unlikely that the dog will develop Cobalamin Malabsorption (Imerslund-Gräsbeck syndrome (IGS)). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.

 

Carrier

Genotype: N / IGS [ 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 Cobalamin Malabsorption (Imerslund-Gräsbeck syndrome (IGS)) 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: IGS / IGS [ Homozygous mutant ]

 

The dog carries two copies of the mutant gene and therefore it will pass the mutant gene to its entire offspring.

The Disease
Musladin-Lueke Syndrome (MLS) manifests with extensive fibrosis of the skin and joints. As puppies, affected dogs fail to thrive. By one year of age the disease stabilizes whereby arthrosis, stiffness, short outer digits as well as a typical flat head shape with higher ear set and slanted eyes are characteristic for this disease. Affected dogs walk upright on their front feeT in what resembles a ballerina stance. Additionally, they show a “happy” temperament.

  4 ) Brittle Bone Disease (Osteogenesis Imperfecta)

Breeds
Beagle , Golden Retriever , Miniature Wire haired Dachshund , Miniature Smooth Haired Dachshund , Standard Smooth Haired Dachshund , Standard Wirehaired Dachshund .
The Disease
Osteogenesis Imperfecta is a generalized, inherited bone defect characterized by extreme fragility of bones and loose joints. The bones can break easily, sometimes they break for no known reason. The long bones are slender and have thin cortices. Calluses and recent fractures may be present. The disease can also cause weak muscles, brittle teeth, curved spine and hearing loss. The cause of the disease is a gene defect that affects how the body makes collagen, a protein that helps make bones strong
Clinical Signs
Clinical signs include pain, spontaneous bone and teeth fractures, loose joints, and reduced bone density on radiography. Primary teeth are extremely thin-walled and brittle Osteogenesis imperfecta can range from mild to severe and symptoms vary from one dog to another.
Trait of Inheritance
In Dachshunds, Osteogenesis imperfecta Is inherited as a autosomal recessive trait, however, in Beagle and Golden Retriever it is inherited as autosomal dominant trait.

  5 ) PK Deficiency (Pyruvate Kinase Deficiency)

Breeds
Basenji , Beagle , Cairn Terrier , Labrador Retriever , Pug , West Highland White Terrier .
The Disease
Pyruvate kinase (PK) is an enzyme critical to the anaerobic glycolytic pathway of energy production in the erythrocyte. If erythrocytes are deficient in PK they are unable to sustain normal cell metabolism and hence are destroyed prematurely. This deficiency manifests as an hemolytic anemia of variable severity with a strong regenerative response. In dogs, the anemia is always severe (PCV 10-20%) whereas in cats the anemia shows a regenerative response. Also associated with the disease in dogs but not cats is a progressive myelofibrosis and osteosclerosis of unknown etiology and this feature, along with liver failure, is the major cause of death in affected dogs. The life expectancy of affected dogs is shortened and most die before 4 years of age. PK deficiency has been recognized in both dogs and cats. The dog breeds involved are the Basenji, Beagle, Dachshund, Eskimo, West Highland White Terriers and the Beagle. In cats, PK deficiency has been described in Abyssinian and Somali cats, as well as DSH cats. The feline disease differs from the canine disease in that affected cats can have a normal life span, only intermittently have anemia, and do not seem to develop either osteosclerosis or liver failure. In all breeds the disease is inherited as an autosomal recessive condition. Heterozygotes (carriers) do not have any clinical signs of disease and lead normal lives. They are able to propagate mutations throughout the population however and it is therefore important that carrier animals be detected prior to breeding. PK deficiency can be detected, using molecular genetic testing techniques, in the Basenji, Beagle, Pug, Labrador Retriever, West Highland White and Cairn Terriers and the Beagle. These tests identify both affected and carrier animals. It is also possible to identify animals deficient in PK activity through enzyme analysis in those breeds where a molecular genetic test is not available.
Clinical Signs
The clinical signs of disease reflect the anemic status of the animal and include exercise intolerance, weakness, heart murmur and splenomegaly. The anemia is macrocytic, hypochromic and highly regenerative in dogs. Radiographs reveal generalized abnormalities in bone density including intramedullary mineralisation of the long bones suggestive of progressive osteosclerosis in dogs.
Trait of Inheritance
PK Deficiency is inherited in an autosomal recessive trait.

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
A primary open angle glaucoma is a genetic dysfunction of the connective tissue in the eye. Thereby, the aqueous fluid is blocked and the pressure of the eyeball rises. Ultimately, the optic nerve and the retina are damaged leading from partial to complete blindness.

Symptoms include widened pupils, red eyeballs, cloudy cornea and increased eye pressure. Raising eye-pressure causes pain, which leads to the dog loses it's appetite, scratches the eyes, rubbing it's head on walls and exhibit aggressive behaviour.

Early diagnosis allows treatment in decreasing the eye-pressure constantly and thereby preventing damage on the optic nerve and retina.

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
Factor VII deficiency is a mild bleeding disorder caused by lack of factor VII (proconvertin) which plays a role in the blood clotting system. Affected dogs bruise easily and nosebleeds maybe seen. There is often prolonged bleeding after surgery or trauma and, in the cases of major surgical procedures or trauma, bleeding maybe severe.

The condition may go unnoticed for long time and discovered only when a surgery is performed or if the dog had an accident, in both cases increased bleeding will be noticed which can be difficult to control. Your vet will suspect a bleeding disorder.

Disease can be managed with the infusion of Frozen Fresh Plasma (FFP). In case of surgery , blood transfusion should be considered.

Please note that Scottish Deerhound can also suffer aother bleeding disorder known as Delayed postoperative hemorrhage (DEPOH) and in fact it is possible for a Scottish Deerhound to be affected with both problems.

Trait of Inheritance
Factor VII Deficiency follows an autosomal recessive mode of inheritance.

Description

Recently, the mutation responsible for this condition has been identified by Dr Urs Giger and researchers at the University of Pennsylvania. The test is now available at LABOKLIN. Factor VII deficiency follows a recessive trait of inheritance, the test identify a dog as affected (2 copies of the abnormal gene), clear (0 copies of the abnormal gene) or carrier (1 copy of the abnormal gene). Only affected dogs with two copies of the affected gene will develop the disease. Since this is am autosomal recessive condition, carrier dogs will not develop the disease but will pass the mutation to their offspring.

  8 ) Catalase Deficiency ( CAT ) / Hypocatalasemia / Acatalasia

Breed
Beagle .
The Disease
Catalase Deficiency (hypocatalasemia or acatalasia) is a rare inherited disorder that is caused by recessive mutation in the CAT gene which is responsible for the production of the anti-oxidative enzyme catalase.

Catalase enzymes regulates the metabolism of hydrogen peroxide, one of many by-products generated during the respiration process. Affected dogs are particularly sensitive to hydrogen peroxide’s oxidative stress, causing painful

It is very unlikely that the dog will develop Catalase Deficiency ( CAT ) / Hypocatalasemia / Acatalasia 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: CAT / CAT [ 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 Catalase Deficiency ( CAT ) / Hypocatalasemia / Acatalasia and will pass the mutant gene to its entire offspring
