1 ) Acute Respiratory Distress Syndrome ( ARDS )
|
| |
|
The Disease |
 |
Acute Respiratory Distress Syndrome (ARDS) is an inherited fatal respiratory disease affecting the Dalmatian breed characterised by impaired pulmonary gas exchange, which leads to inflammation and carries substantial risk of death.
The main clinical signs include progressive abnormally rapid breathing (tachypnea) and breathing difficulty (dyspnea) leading to a severe respiratory distress and euthanasia.
Prevalence: it is estimated that 1.7 % of Dalmatians are carriers) |

The Disease |
 |
We are pleased to announce that in cooperation with professor Leeb of the University of Bern in Switzerland, Laboklin is now able to offer a DNA test for the detection of the mutation which causes Inflammatory Pulmonary Disease ( IPD ) in Collies and the test is now available for ordering.
Inflammatory Pulmonary Disease ( IPD ) is an inherited lung disease affecting the Collie breed and characterised by recurrent pneumonia, clinical symptoms were seen when affected puppies were only few days old and include foamy vomiting, shallow breathing, cough, increased breathing sounds and fever. Affected dogs responded to therapy with antibiotics and secretolytics, but tended to relapse quickly without antibiotic treatment. |

3 ) Lethal Lung Disease (LLD / LAMP3)
|
| |
|
The Disease |
 |
|
Lethal lung disease in new born Airedale Terrier dogs is a genetic disease caused by a recessive variant in the lysosome associated membrane LAMP3 gene. This genetic defect causes a defect in the maturation of the Surfactant producing organelle of the lung epithelium. Surfactants are mixture of lipids and proteins essential for life that form a thin surface lining film in the gas exchange compartment of the lungs, the alveolus. Surfactants reduces surface tension on the surface of these cells, essential to breathing. Surfactants are produced by the vacuoles which are closed sacs, made of membranes with inorganic or organic molecules inside, such as enzymes. In affected puppies the vacuoles don’t mature and therefore are unable to produce the surfactant causing lethal hypoxic respiratory distress and failure within the first days or weeks of life in affected puppies.

4 ) Upper Airway Syndrome ( UAS )
|
| |
|
The Disease |
 |
Upper airway Syndrome is an inherited disease caused by a mutation in the ADAMTS3 gene and characterised by airway oedema which leads to fluid retention in the tissue that lines the airways and makes it more likely that dogs with the mutation will develop breathing obstructions.
Dogs homozygous for the mutation (UAS/ UAS ) are at significantly higher risk of developing the disease than dogs which are heterozygous (N / UAS) |
|
|
|
|
Description |
|
The Norwich Terrier is considered to be a “mesocephalic” breed. While brachycephalic dogs are predisposed to the Brachycephalic Obstructive Airway Syndrome (BOAS), the Upper Airway Syndrome (UAS) could often be observed at dogs of the breed Norwich Terrier. Respiratory effort, resulting in laboured breathing, intolerance to heat or exercise, cyanosis and collapse are typical symptoms of both syndromes (UAS and BOAS).
In the breed Norwich Terrier, a variant in the ADAMTS3 gene could be found to be associated with the UAS. Homozygous affected dogs often show an elongated soft palate protruding caudally into the epiglottis, the laryngeal cartilage is inverted into the lumen of the airway and the laryngeal saccules are everted.

|
Trait of Inheritance |
|
Upper Airway Syndrome ( UAS ) has an autosomal recessive trait of inheritance.

Clear
Genotype: N / N [ Homozygous normal ]
The dog is noncarrier of the mutant gene.
It is very unlikely that the dog will develop Upper Airway Syndrome ( UAS ). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.
Carrier
Genotype: N / ADAMTS3 [ 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 Upper Airway Syndrome ( UAS ) 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: ADAMTS3 / ADAMTS3 [ 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 Upper Airway Syndrome ( UAS ) and will pass the mutant gene to its entire offspring

This test is part of the Official UK Kennel Club DNA Testing Scheme in Old English Sheepdog (Bobtail).
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 |
 |
Primary ciliary dyskinesia (PCD) is an autosomal-recessive genetic disease characterized by recurrent infections of the respiratory tract as well as reduced male fertility. Around 50% of the affected dogs develop situs inversus (Kartagener syndrome). The underlying cause is a motility defect in the respiratory cilia responsible for airway clearance and in the flagella responsible for propelling sperm cells.
In Old English Sheepdod the disease is caused by a mutation in the CCDC39 gene, while in Alaskan Malamute it is caused by mutation in NME5 gene |
|
|
|
|
Clinical Signs |
|
Symptoms include chronic inflammation of upper and lower airways, coughing, nasal discharge, wheezing, bronchopneumonia and inflamation of the ear.
