Screening Scheme Description

DNA test - JLPP
Juvenile Laryngeal Paralysis & Polyneuropathy

Details about the disease

JLPP is a disease that causes deterioration of the nervous system. The longest nerve which controls the muscles of the larynx (voice box) is affected first. This leads to muscle weakness and obstruction of air flow into the lungs after exercise or when the dog is hot.

Clinical signs

Clinical signs include noisy breathing, choking and regurgitation of food and water. Signs also include a wobbly gait due to affected nerves that control the hind leg muscles. Other signs include eye development abnormalities. Clinical signs usually start at a few weeks of age.

How it is 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.
