DNA test - ENM (Hereditary necrotising myelopathy)

Details about the disease

ENM is a recessive spinal degenerative disease whereby the white matter of the spinal cord degrades in the neck region, affecting the motor function of the muscles of the hind limbs.

Clinical signs

Hereditary necrotising myelopathy causes progressive spinal degeneration in affected dogs. Clinical signs begin with paralysis of the hind limbs, an inability to place their feet, scuffed toes, excessively worn nails, shuffling and loss of coordination before progressing to an inability to walk within a few weeks. Early signs can usually be seen between 3 to 12 months of age and unfortunately there is no cure, resulting in the death of the dog.

How is it inherited?

The disease is described as an autosomal-recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.

How to submit DNA test results to The Kennel Club

The laboratories listed above do not send your dog's DNA test results to The Kennel Club. To have these results placed on your dog's record please submit them yourself by scanning and emailing them to our health results team.

What we require on the results certificate

Please note that we require at least two forms of identification on the result certificate. These must include the dog's microchip or tattoo number along with either the dog's registered name or registered number. Results without these details cannot be accepted by us.

Where will your dog's results be published once you have submitted them?

DNA test results received by The Kennel Club are recorded on to the dog's record in the registration database, and are published:

Breeding advice and what your dog's results mean
