Genes affected

FBP1 (HGNC:3606): (fructose-bisphosphatase 1) Fructose-1,6-bisphosphatase 1, a gluconeogenesis regulatory enzyme, catalyzes the hydrolysis of fructose 1,6-bisphosphate to fructose 6-phosphate and inorganic phosphate. Fructose-1,6-diphosphatase deficiency is associated with hypoglycemia and metabolic acidosis. [provided by RefSeq, Jul 2008]

FBP1 Gene-Disease associations (from GenCC):

• fructose-1,6-bisphosphatase deficiency
