Hereditary hemolytic anemia phosphoglycerate kinase deficiency

Hereditary deficiency of phosphoglycerate kinase (PGK) is associated with hereditary hemolytic anemia and often with central nervous system dysfunction and/or myopathy. The first case, reported by Kraus et al. (K24), is a heterozygous female, and the results are not so clear. The second family, reported by Valentine et al. (V3), is a large Chinese family, whose pedigree study indicates that PGK deficiency is compatible with X-linked inheritance. To date, 22 families have been reported (04, T25, Y3). Nine of these have manifested both symptoms five have shown only hemolysis seven have shown the central nervous system dysfunction and/or myopathy but without hemolysis and one case, PGK Munchen, is without clinical symptoms (F5). PGK II is an electrophoretic variant found in New Guinea populations (Y2). Red blood cell enzyme activity, specific activity, and the kinetic properties of this polymorphic variant are normal.

A different problem results from deficiency of enzymes of glycolysis such as phosphofructokinase (see Box 20-D), phosphoglycerate rnutase, and pyruvate kinase. Lack of one isoenzyme of phosphoglycerate rnutase in muscle leads to intolerance to strenuous exercise/ A deficiency in pyruvate kinase is one of the most common defects of glycolysis in erythrocytes and leads to a shortened erythrocyte lifetime and hereditary hemolytic anemia.s...
