However, a survey of erythrocyte pyruvate kinase deficiency (OMIA 000844-9685) revealed mutant allele frequencies of the PKLR:c.707-53G>A mutation to be 0.214 in Abyssinian cats, 0.229 in Somali cats, 0.016 in Bengal cats, and 0.008 in American Shorthair cats [30]. This evidence concerns the gene PKLR and Hemolytic anemia due to red cell pyruvate kinase deficiency.
