Pyruvate kinase (PK) deficiency, including:
Red cell pyruvate kinase (PK) deficiency;
Pyruvate kinase hyperactivity

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 PK-LR gene. It has also been found that a specific mutation in the PKLR gene causes hereditary increase of red blood cell ATP.
