Phosphoglycerate kinase disease (systemic); Anemia, Hemolytic with PGK Deficiency;synonyms: Erythrocyte Phosphoglycerate Kinase Deficiency, PGK, andPhosphoglycerokinase; Phosphoglycerate kinase deficiency is an extremely rare inherited metabolic disorder characterized by deficiency of the enzyme phosphoglycerate kinase; This enzyme is essential for the breakdown of glycogen, resulting in the release of energy; Symptoms and findings associated with the disorder may include low levels of circulating red blood cells (hemolytic anemia); varying degrees of mental retardation; rapidly changing emotions (emotional lability); an impaired ability to communicate through and/or to comprehend speech or writing (aphasia); exercise-induced pain, stiffness, or cramps; enlargement of the spleen (splenomegaly); and/or paralysis of one side of the body (hemiplegia); In most cases, phosphoglycerate kinase deficiency is inherited as an X-linked genetic trait; In such cases, the disorder is fully expressed in males only; however, some females who carry one copy of the disease gene (heterozygotes) may have hemolytic anemia--------------[NORD 2005]--------------

homozygous male includes systemic problems: mentally retarded with neurological syndromes; heterozygous female usually just rbc problems wuith hemolytic anemia
