Cavalier King Charles Spaniel
This test is part of the Official UK Kennel Club DNA Testing Scheme in Cavalier King Charles Spaniel.
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.
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.
Episodic Falling is a genetic neurological disorder found in Cavalier King Charles Spaniels. Episodes are usually triggered by exercise, stress or excitement and are characterised by increased muscle tone and stiffness throughout the thoracic and pelvic limbs resulting in a characteristic 'deer-stalking' position and or collapse. The onset of symptoms is usually between fourteen weeks and four years of age but may appear at any age. Clinical symptoms vary in severity ranging from mild, occasional falling to freezing or seizure-like episodes lasting hours. Severity of the episodes can increase or decrease as the dog gets older. There is no standard pattern to the attacks.
The disease is also known as Exercise-Induced Paroxysmal Hypertonicity, Falling Cavaliers and Collapsing Cavalier Syndrome.
Prof. Dr. Robert Harvey of the London School of Pharmacy has recently identified the underlying genetic defect causing Episodic Falling in Cavalier King Charles Spaniels. LABOKLIN have recently implemented the genetic test for this disease under licence from the London School of Pharmacy. This test is currently patented within Europe, with Laboklin as the testing laboratory.
Trait of Inheritance
Episodic Falling is inherited as a autosomal recessive trait
It is very unlikely that the dog will develop Episodic Falling in Cavalier King Charles Spaniel (EF). The dog will never pass the mutation to its offspring, and therefore it can be bred to any other dog.
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 Episodic Falling in Cavalier King Charles Spaniel (EF) 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)
