KEGG   DISEASE: Pyruvate kinase (PK) deficiencyHelp
Entry
H01096                      Disease                                

Name
Pyruvate kinase (PK) deficiency
  Subgroup
Red cell pyruvate kinase (PK) deficiency
Pyruvate kinase hyperactivity
Description
Pyruvate kinase (PK) deficiency is inherited metabolic disorder caused by mutations in PKLR that encodes both L-PK (expressed in liver, renal cortex, and small intestine) and R-PK (restricted to erythrocytes). The symptoms include jaundice, enlargement of the spleen, and hemolysis, leading to anemia. One hundred fifty-eight mutations associated with non-spherocytic haemolytic anaemia and eight polymorphic sites have been so far reported in the PKLR gene. It has also been found that a specific mutation in the PKLR gene causes hereditary increase of red blood cell ATP.
