Pyruvate kinase deficiency

What is Pyruvate kinase deficiency?

Known in the field of Canine Science, Pyruvate kinase deficiency is a genetic disorder affecting dogs. It involves an inherited lack of the enzyme Pyruvate kinase, critical in energy production for cells. The deficiency of this enzyme results in insufficient energy for the cells, leading to a range of health issues.

The Role of Pyruvate kinase

Pyruvate kinase plays a crucial part in the process of glycolysis, where the body converts glucose into energy. When the enzyme falls short, it results in the premature destruction of red blood cells. The body, then, can't replenish these cells rapidly enough, causing anemia and other related conditions.

Impact of Pyruvate kinase deficiency on Dogs

In dogs, Pyruvate kinase deficiency results in severe hemolytic anemia, meaning their body does not have enough red blood cells to fuel organs with oxygen. Dogs with this condition may display weakness, rapid heart rate, pale gums, and stunted growth. Without treatment, life expectancy of dogs affected with this disorder is significantly reduced.

Diagnosis and Treatment of Pyruvate kinase deficiency

To diagnose Pyruvate kinase deficiency, a veterinarian will likely execute DNA testing or detailed blood tests. There's currently no cure for this genetic disorder, and treatment typically focuses on managing symptoms and improving the quality of life for affected dogs. Regular blood transfusions, dietary adjustments, and medication are common approaches to managing this life-threatening condition.

Prevalence and Prevention

Pyruvate kinase deficiency is found most often in certain breeds such as Labrador Retrievers, Beagles, and West Highland White Terriers. Responsible breeding includes genetic testing of breeding pairs to prevent this disorder's inheritance.
