Presentation
We present a family with muscle phosphoglycerate mutase (PGaM) deficiency, mild glycogen storage and some exertional myalgia. Investigations of muscle biopsy tissue showed a residual PGaM activity in muscle due to a small amount of brain isoenzyme. [ncbi.nlm.nih.gov]
However, the focus of the book remains clinical, describing symptoms and signs at presentation, how to come to a diagnosis and methods for treatment. As with the previous edition, the book can be used in two main ways. [books.google.com]

Myalgia

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]

Muscle Cramp
Conclusion: Although the clinical manifestations of PGAMD mimic McArdle disease with respect to the presence of exertional muscle cramps, rhabdomyolysis, and myoglobinuria, this study shows that cycle exercise responses are strikingly different. [utsouthwestern.influuent.utsystem.edu]
Clinical features may include hepatomegaly, hypoglycemia, muscle cramps, exercise intolerance, and progressive fatigue and weakness. Preliminary biochemical testing may be helpful in making a diagnosis. [sjhbangorlab.testcatalog.org]

Muscle Contracture
Phosphoglycerate mutase enzyme deficiency in muscle causes a metabolic myopathy (glycogen storage disease X) characterized by exertional muscle contractures, weakness, hyperCKemia, and myoglobinuria. [ncbi.nlm.nih.gov]
Muscle contractures do not occur after ischemic exercise. Numerous episodes of supraventricular tachycardia occurred in an infant with Thomson's disease. [euroformhealthcare.biz]
Prolonged muscle spasm (muscle contracture) is not uncommon and can lead to RM. [ojrd.biomedcentral.com]

Suggestibility
Muscle biopsy revealed subsarcolemmal collections suggestive of tubular aggregates. Phosphoglycerate mutase activity was 8% of the reference value. [ncbi.nlm.nih.gov]
Gomori-trichome and NADH showed subsarcolemmal depositions (0.01% of the fibres) suggesting tubular aggregates (Fig. 1 ). PGAM activity in muscle homogenate [ 4 ] was moderately reduced (141 U/g wet weight, normal 332 88). [link.springer.com]
