Essential fructosuria is a genetic condition that is inherited in an autosomal recessive manner. [3] Mutations in the KHK gene, located on chromosome 2p23.3-23.2 are responsible. The incidence of essential fructosuria has been estimated at 1:130,000. [4] The actual incidence is likely higher, because those affected are asymptomatic. [citation ...
Classic form: Symptoms usually appear in early childhood. Myopathy. Exercise-induced muscle cramps, weakness and sometimes rhabdomyolysis. Nausea and vomiting following strenuous exercise. Myoglobinuria, haemolytic anaemia, Hyperuricemia is common. High levels of bilirubin and jaundiced appearance possible. Late-onset form: Presents later in life.
Treatment of HFI depends on the stage of the disease, and the severity of the symptoms. Stable patients without acute intoxication events are treated by careful dietary planning that avoids fructose and its metabolic precursors. Fructose is replaced in the diet by glucose, maltose or other sugars.

Fructosuria or hepatic fructokinase deficiency is a rare but benign inherited metabolic disorder. [8] This condition is caused by a deficiency of fructokinase in the liver. Affected individuals usually display a large blood fructose concentration after the ingestion of fructose, sucrose or sorbitol. [ 9 ]
Some of the symptoms that can occur with metabolic disorders are lethargy, weight loss, jaundice and seizures. The symptoms expressed would vary with the type of metabolic disorder. There are four categories of symptoms: acute symptoms, late-onset acute symptoms, progressive general symptoms and permanent symptoms. [5]
The lack of two important enzymes in fructose metabolism results in the development of two inborn errors in carbohydrate metabolism – essential fructosuria and hereditary fructose intolerance. In addition, reduced phosphorylation potential within hepatocytes can occur with intravenous infusion of fructose.
The first known description of a patient with this condition was published in 1970 in The Lancet journal. [1]Early research into the disorder was conducted by a team led by Anthony S. Pagliara and Barbara Illingworth Brown at Washington University Medical Center, based on the case of an infant girl from Oak Ridge, Missouri.
