Abstract Background: Fructose-1,6-bisphosphatase (FBPase) deficiency is a rare disorder of glucose metabolism, mainly revealed by hypoglycemia and lactic acidosis. The disease is caused by a mutation of FBP1 gene, which is clustered in a 31-kb region on chromosome 9q22. Case presentation: We described a two-and-half-year-old boy diagnosed as FBPase deficiency. The result of gene analysis showed that the patient had a compound heterozygote for the G164S and P308R, respectively inherited from his father and mother. To some degree, mutations are associated with activity of enzyme, which is corresponding to the level of glucose and extent of brain damage. Patients are advised to reduce intake of fructose and sucrose and avoid long-term fasting in order to reduce the risk of metabolic decompensation. Conclusions: This report would like to provide profound insights of FBPase deficiency.

Prolonged exercise increased the concentrations of the hexose phosphates and phosphoenolpyruvate and depressed those of fructose 1,6-bisphosphate, triose phosphates and pyruvate in the liver of the rat. Since exercise increases gluconeogenic flux, these changes in metabolite concentrations suggest that metabolic control is exerted, at least, at the fructose 6-phosphate/fructose 1,6-bisphosphate and phosphoenolpyruvate/pyruvate substrate cycles. Exercise increased the maximal activities of glucose 6-phosphatase, fructose 1,6-bisphosphatase, pyruvate kinase and pyruvate carboxylase in the liver, but there were no changes in those of glucokinase, 6-phosphofructokinase and phosphoenolpyruvate carboxykinase. Exercise changed the concentrations of several allosteric effectors of the glycolytic or gluconeogenic enzymes in liver; the concentrations of acetyl-CoA, ADP and AMP were increased, whereas those of ATP, fructose 1,6-bisphosphate and fructose 2,6-bisphosphate were decreased. The effect of exercise on the phosphorylation-dephosphorylation state of pyruvate kinase was investigated by measuring the activities under conditions of saturating and subsaturating concentrations of substrate. The submaximal activity of pyruvate kinase (0.5 mM-phosphoenolpyruvate), expressed as percentage of Vmax., decreased in the exercised animals to less than half that found in the controls. These changes suggest that hepatic pyruvate kinase is less active during exercise, possibly owing to phosphorylation of the enzyme, and this may play a role in increasing the rate of gluconeogenesis.
