Pyruvate kinase deficiency in cats is an inherited hemolytic anemia that is passed down from parents to offspring. Erythrocytic pyruvate kinase deficiency and AB blood types in Australian Abyssinian and Somali cats. Pyruvate Kinase Deficiency is an hereditary disorder that affects red blood cells, which carry oxygen to the body’s tissues. What is pyruvate kinase deficiency? Pyruvate Kinase Deficiency In this disorder, the red blood cells of Abyssinians fail to metabolize which further leads to anemia or other blood related disorders. To compensate for this deficiency, there is persistence of the M2-type PK isoenzyme, which is less stable than the R … Erythrocyte pyruvate kinase (PK) deficiency is an inherited glycolytic erythroenzymopathy caused by mutations of the PKLR gene. Pyruvate kinase deficiency is a genetic blood disorder characterized by low levels of an enzyme called pyruvate kinase, which is used by red blood cells.Without pyruvate kinase, red blood cells break down too easily, resulting in low levels of these cells (hemolytic anemia). The objective of this study was to examine clinical signs, laboratory parameters, and course of disease in Abyssinian and Somali cats with pyruvate kinase (PK) deficiency. Bone marrow transplantation is the only available treatment for PK deficient cats. Pyruvate Kinase (PK) deficiency is an autosomal recessive genetic disease (a glycolytic erythroenzymopathy) in Abyssinian, Bengal, Domestic shorthair and Somali cats worldwide. Cats which inherit one copy of the defective gene, from one parent only, will not be clinically affected but will carry the gene and may pass it onto offspring. A report including these markers is available upon request. Pyruvate kinase (PK) deficiency is an inherited erythrocyte enzyme deficiency that was first documented in Abyssinian, Somali, and domestic shorthair cats in the early 1990s. A deficiency of pyruvate kinase prevents this energy production. The main consequence of PK deficiency is the development of anaemia. If you are considering buying an Abyssinian or Somali cat, always ask the breeder if they have had their cats tested for PK deficiency and ask to see the results. The cat will not have pyruvate kinase deficiency, but may pass the mutation to their offspring. The identity markers are not listed on the results page, but are stored in Neogen's database for future reference. The cat carries two copies of the mutant gene and therefore it will pass the mutant gene to its entire offspring. He or she will then perform a complete physical examination, as well a biochemistry profile, urinalysis, and complete blood count (CBC). Pyruvate kinase deficiency is a rare disorder that affects both men and women. Clinical signs closely mimic other types of hemolytic anemia, including auto-immune hemolytic anemia. Pyruvate kinase deficiency (PKDef) is an inherited hemolytic anemia caused by a defect in the enzyme pyruvate kinase. Breeds more prone to PK deficiency include the Abyssinian, Somali, and domestic shorthair cats. Some cats die or require euthanization while others maintaine an adequate quality of life.

PK deficiency is inherited as an autosomal recessive condition. Quick Summary Erythrocyte pyruvate kinase deficiency (PK deficiency) is an inherited hemolytic anemia caused by insufficient activity of its namesake regulatory enzyme. Feline pyruvate kinase deficiency testing is recommended for several breeds including Bengals, Egyptian Maus, La Perms, Maine Coon cats, Norwegian Forest cats, Savannahs, Siberians, and Singapuras, in addition to Abyssinians and Somalis. The biochemistry profile, meanwhile, may show an excess of iron in the blood (hyperferremia), mild increase in bilirubin, and slight increase in liver enzymes. Erythrocyte Pyruvate Kinase Deficiency (PK Deficiency) is an inherited hemolytic anemia caused by insufficient activity of this regulatory enzyme which results in instability and loss of red blood cells. A causative mutation of the feline PKLR gene was originally identified in Abyssinian and Somali cats in the U.S.A. The clinical course of 25 PK-deficient cats was followed over a time period of 0.8-11.3 years (median 4.3). Specialist veterinary laboratories are able to offer this test which, if performed properly, will be highly reliable and able to show if a cat is completely healthy, a carrier, or contains two copies of the abnormal gene and is therefore affected with PK deficiency. A single pair of genes is responsible for development of PK deficiency. Cats that undergo a bone marrow transplant may have a normal lifespan. A 2-year-old female neutered Somali cat was presented with vomiting and acute onset jaundice 1 year after diagnosis of pyruvate kinase (PK) deficiency. The cat is likely to develop PK Deficiency (Pyruvate Kinase Deficiency) and will pass the mutant gene to its entire offspring The anemia can be intermittent, with the cat showing no symptoms at all except in shorter periods.
