Muscle pain, exercise intolerance, hemolytic anemia Phosphofructokinase deficiency is a rare muscular metabolic disorder , with an autosomal recessive inheritance pattern. It is characterized as a deficiency in the Phosphofructokinase (PFK) enzyme throughout the body, including the skeletal muscles and red blood cells.
The symptoms of exercise intolerance, abnormal muscle fatigue, myalgia (muscle pain), arrhythmia, possible fixed proximal muscle weakness, lipid deposits, possible episodes of rhabdomyolysis, with symptoms becoming evident or worsening while fasting, during a fever, during low-intensity aerobic activity or after prolonged activity–all these ...
Muscle atrophy is the loss of skeletal muscle mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability.
Muscle weakness can also be classified as either "proximal" or "distal" based on the location of the muscles that it affects. Proximal muscle weakness affects muscles closest to the body's midline, while distal muscle weakness affects muscles further out on the limbs. Proximal muscle weakness can be seen in Cushing's syndrome [18] and ...

As skeletal muscle relies predominantly on glycogenolysis for the first few minutes as it transitions from rest to activity, as well as throughout high-intensity aerobic activity and all anaerobic activity, individuals with GSD-V experience during exercise: sinus tachycardia, tachypnea, muscle fatigue and pain, during the aforementioned ...
