Abstract
Two kindreds of phosphofructokinase (PFK) deficiency associated with congenital nonspherocytic hemolytic anemia and mild myopathy were found in Japan. Both probands had jaundice, gallstones, and slight to moderate degree of exercise intolerance. They showed decreased level of red cell PFK activity and no increase of blood lactate in forearm ischemic exercise test. We studied these probands' red cell PFKs by partial purification and condensation. Muscle type isozyme of PFK in both cases was not demonstrable in starch gel electrophoresis and DEAEโSephadex chromatography. The clinical symptoms are considered to be due to a defect of muscle type isozyme.

Clinical and metabolic studies were performed in four members of a Spanish family with partial (50%) 6 phosphogluconate dehydrogenase (6PGD) deficiency. In all cases the activities of 6 phosphogluconolactone (6PGL) and glutathione reductase (GR) were normal, and the molecular characterization perfor
## Communicated by Francesco Giannelli DNA sequencing revealed seven different glucose-6-phosphate dehydrogenase (G6PD) mutations in G6PD deficient subjects from 10 Polish families. Among them we found two novel mutations: 679CยฎT (G6PD Radlowo, class 2) and a 1006AยฎG (G6PD Torun, class 1). Variant
