Phosphofructokinase deficiency
Specialty	Endocrinology

Phosphofructokinase deficiency, also known as Glycogen storage disease type VII or Tarui's disease, is metabolic disorder with autosomal recessive inheritance.

It may affect humans as well as other mammals (especially dogs). In humans it is the least common type of glycogen storage disease.

Pathophysiology

In this condition, a deficiency of the M subunit of the phosphofructokinase enzyme impairs the ability of cells such as erythrocytes and rhabdomyocytes to use carbohydrates (such as glucose) for energy.

Unlike most other glycogen storage diseases, it directly affects glycolysis.

Presentation

The disease presents with exercise-induced muscle cramps and weakness (sometimes rhabdomyolysis), as well as with haemolytic anaemia causing dark urine a few hours later.
