Genetic test for pyruvate kinase deficiency of Basenjis.
Pyruvate kinase (PK) deficiency is an autosomal, recessive, inherited disease of Basenjis that causes chronic, regenerative, hemolytic anemia. Diagnostic methods currently used to identify carrier animals rely on measurement of erythrocyte PK activity and frequently give equivocal results. A genetic test incorporating polymerase chain reaction amplification of genomic DNA and restriction fragment length polymorphism has been developed to determine the PK genotype of Basenjis. To determine whether results of this genetic test compared with results of standard tests for PK deficiency, erythrocyte PK activity, hematocrit, and reticulocyte counts were determined in, and the genetic test was performed on, 24 dogs. The genetic test accurately identified the 11 dogs whose PK genotype was known prior to this study, and results were consistent with results of measuring erythrocyte PK activity in the remaining 13 dogs. The genetic test may be of value in determining PK genotype of Basenjis.
