Management and treatment Unfortunately, there is no medical cure for this disorder. Check this box if you wish to receive a copy of your message. Lack of activity of the erythrocyte isoform of AMP deaminase has been described in subjects with low plasma uric acid levels without obvious clinical relevance and will not be described further.

Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. Diagnostic methods The diagnosis is based on histochemical staining or biochemical analysis of a muscle biopsy showing a lack of muscle adenylate deaminase activity, or on molecular identification of the disease-causing mutation. Patients may also present with extraimmune manifestations including neurodevelopmental deficits, behavioral disorders, sensorineural deafness, and skeletal and hepatic abnormalities as a result of the systemic nature of ADA expression.

Etiology The vast majority of patients with this disease are homozygous for the nonsense CT mutation in the AMPD1 adenosine monophosphate deaminase 1 gene. Smooth muscle or other organs are not affected as the disorder is associated with a specific lack of skeletal muscle adenylate deaminase activity. The diagnosis is based on histochemical staining or biochemical analysis of a muscle biopsy showing a lack of muscle adenylate deaminase activity, or on molecular identification of the disease-causing mutation.

Myoadenylate deaminase deficiency is an inherited disorder of muscular energy metabolism with a lack of AMP deaminase activity in skeletal muscle. Surprisingly, however, asymptomatic AMP deaminase-deficient subjects have been reported, indicating that additional factors are likely to be involved in the development of myopathic symptoms. This mutation creates an early stop codon thus preventing the synthesis of an enzymatically active protein.
