Hemolytic anemia due to pyruvate kinase deficiency

Hemolytic anemia due to pyruvate kinase deficiency is an inherited, autosomal recessive metabolic disorder affecting red blood cells, caused by mutations in the *PKLR* gene Clinically recognized as a leading cause of hereditary nonspherocytic hemolytic anemia, it exhibits broad phenotypic severity that spans from mild, fully compensated hemolysis to life-threatening neonatal anemia requiring frequent transfusions

Hemolytic anemia due to pyruvate kinase deficiency is an inherited, autosomal recessive metabolic disorder affecting red blood cells, caused by mutations in the *PKLR* gene Deficient activity of the glycolytic enzyme pyruvate kinase impairs adenosine triphosphate (ATP) production in mature erythrocytes, compromising cellular membrane integrity and resulting in premature extravascular hemolysis, predominantly within the spleen

Deficient activity of the glycolytic enzyme pyruvate kinase impairs adenosine triphosphate (ATP) production in mature erythrocytes, compromising cellular membrane integrity and resulting in premature extravascular hemolysis, predominantly within the spleen Defining clinical features and complications include chronic pallor, fatigue, scleral icterus, jaundice, splenomegaly, cholelithiasis, and systemic iron overload
