Screening Scheme Description

DNA test - PDP-1
Pyruvate dehydrogenase phosphate 1 deficiency

Spaniel (Clumber)

Details about the disease

The enzyme Pyruvate Dehydrogenase Phosphatase 1 (PDP1) has a key role in cell metabolisation, which is essential for the conversion of food to ATP (the main energy source of cells).

Clinical signs

PDP1 is a metabolic disorder characterised by exercise intolerance and post-exercise collapse. There may also be neurological signs.

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.
