Breeds

Relevance Rating: The test is unknown, there is no evidence (i.e. research) available, or it has not been evaluated yet. These tests may or may not be meaningful for these breeds

General

Disease Name
Pyruvate Dehydrogenase Deficiency
Mutation
c.754C > T
Test Type
Genetic Disease/Disorder
Details
Deficiency in pyruvate dehydrogenase phosphatase 1 is characterized by exercise intolerance, lactic acidosis, and collapse after exercise. Management includes exercise restriction and a high-fat diet with thiamine and carnitine supplementation. Breeders are recommended to use DNA tests to identify clear and carrier dogs to slowly breed away from this specific condition, as it seems to be present currently only in fairly rare breeds - Clumber and Sussex Spaniel.
Details 2
Deficiency in pyruvate dehydrogenase phosphatase 1 in Clumber and Sussex Spaniels is characterized by exercise intolerance, lactic acidosis, and collapse after exercise. The causative mutation is the same in these breeds. Affected dogs show exercise intolerance, lactic acidosis, and post-exercise collapse. Management includes exercise restriction and a high-fat diet with thiamine and carnitine supplementation (Cameron et al., 2007).
