© 1983 American Academy of Neurology Exercising muscle does not produce hypoxanthine in adenylate deaminase deficiencyDepartment of Neurology, Washington University School of Medicine, St. Louis, MO. The failure of forearm exercise to increase plasma hypoxanthine in subjects with adenylate deaminase deficiency confirms this enzyme's role in hypoxanthine production by normal forearm exercise. The conversion of adenosine monophosphate (AMP) to hypoxanthine may reflect an alternative method of adenosine triphosphate (ATP) regeneration in working muscle.
