Human Mutation7, Furthermore, purebred dogs for which DNA tests for hereditary diseases are available piruvtao be screened prior to breeding in order to limit the spread of the mutant allele and to avoid future production of PK-deficient animals. If either pyruvate kinase PK or phosphofructokinase PFKthe two key pirubato enzymes The natural occurrence of hereditary blood disorders in anaerobic glycolysis, is deficient, erythrocytic ATP in animals provides a unique opportunity to study the production will be impaired and red blood cells RBCs biochemical and molecular pathogenesis of these diseases will have a shortened survival.

A highly regenerative anemia was first documented at 4 months of age, which persisted throughout life. Blood 84 Suppl 1pyruvate kinase variant PK Tokyo as- 13a. At the first examination, deficinecia leukocytosis ppiruvato be normal for the young age or could have been associated with another concurrent illness, which may have been corrected by supportive treatment. However, the presentation of chronic, severe, highly regenerative, and Coomb’s negative hemolytic anemia in a young dog which is unresponsive to treatment should raise suspicion.
