Phosphofructokinase deficiency, also known as Glycogen storage disease type VII or Tarui's disease, is a muscular metabolic disorder, with an autosomal recessive inheritance pattern.
It may affect humans as well as other mammals (especially dogs). In humans it is the least common type of glycogen storage disease. It was named after the Japanese Physician, Seiichiro Tarui (1927- ) who first observed the condition in 1965.
