Disease

KPYR_HUMAN Defects in PKLR are the cause of pyruvate kinase hyperactivity (PKHYP) [MIM:102900; also known as high red cell ATP syndrome. This autosomal dominant phenotype is characterized by increase of red blood cell ATP.[1] Defects in PKLR are the cause of pyruvate kinase deficiency of red cells (PKRD) [MIM:266200. A frequent cause of hereditary non-spherocytic hemolytic anemia. Clinically, pyruvate kinase-deficient patients suffer from a highly variable degree of chronic hemolysis, ranging from severe neonatal jaundice and fatal anemia at birth, severe transfusion-dependent chronic hemolysis, moderate hemolysis with exacerbation during infection, to a fully compensated hemolysis without apparent anemia.

Function

KPYR_HUMAN Plays a key role in glycolysis (By similarity).
