A 52-year-old African-American woman presented with exertional muscle contractures, myalgias, and weakness since childhood including an episode of rhabdomyolysis. Neurologic examination and EMG were normal.[pubfacts.com]
Clinically, patients with PGAM deficiency are asymptomatic, except when they engage in brief, strenuous efforts, which may trigger myalgias, cramps, muscle necrosis, and myoglobinuria.[experts.umich.edu]
Conclusion: Although the clinical manifestations of PGAMD mimic McArdle disease with respect to the presence of exertional musclecramps, rhabdomyolysis, and myoglobinuria, this study shows that cycle exercise responses are strikingly different.[utsouthwestern.influuent.utsystem.edu]
