A case of liver glycogen storage disease with amylo 1,6-glucosidase deficiency is reported. Enlarged liver was found at birth, and it is now accompanied by splenomegaly, low fasting blood glucose with ketonuria, elevation of transaminase values and glycogen accumulation with connective periportal tissue in liver histological study. In this glucogenosis results of functional tests on carbohidrate metabolism and glycogen enzymatic assay showed a direct relationship between functional and biochemical behaviour of liver cells. Amylo 1,6-glucosidase deficiency is accompanied by absence of glucogenolysis when glucagon is administrated after a long fast, and an increase of blood glucose when glucagon is administrated after food ingestion. Glycolisis tests show blood lactate elevation when some hexose or alanine are administrated; glyconeogenesis tests show blood glucose elevation when hexose, alanine or glycerol are administrated.

Two cases of red cell aldolase deficiency associated with congenital nonspherocytic hemolytic anemia are reported. The proband is a fourteen-month-old Japanese boy. Consanguineous marriage was not proven but probable in this family, as the parents were born in the same small island. The proband had moderate to mild anemia aggravated by upper respiratory infections, 1 cm hepatomegaly and 2.5 cm splenomegaly, but was unremarkable in other respects and has thus far not shown mental or growth retardation. He did not have dysmorphic features. The red cell aldolase activity was 6% of the normal mean. The enzyme was unstable with respect to heat, and Km for fructose 1,6-diphosphate (F-1,6-DP) was high. The parents and other heterozygotes showed intermediate activity between that of the proband and that of normal subjects. Red cell F-1,6-DP concentration in this case was remarkably increased. Red cell glucose consumption, and lactate formation, as well as hexose monophosphate shunt activity, were decreased as compared with a comparable reticulocyte-rich hereditary spherocytosis patient. Hexose monophosphate dehydrogenase by a high concentration of F-1,6-DP in his red cells. As a result of family study, another homozygous aldolase deficiency case associated with hemolytic anemia was found. He is 13 years old and a nephew of the proband's paternal grandmother. His hemolytic anemia also is moderate to mild and aggravated by upper respiratory infections. He does not seem to have mental or growth retardation, nor does he possess dysmorphic features.
