Smooth muscle or other organs are not affected as the disorder is associated with a specific lack of skeletal muscle adenylate deaminase activity.

The vast majority of patients with this disease are homozygous for the nonsense CT mutation adenisina the AMPD1 adenosine monophosphate deaminase 1 gene. 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. Genetic counseling Transmission is autosomal recessive.

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.

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. Additional information Further information on this disease Classification s 3 Gene s 2 Clinical signs and symptoms Publications in PubMed Other website s 6.

Clinical description The vast majority of patients suffer from post-exercise symptoms: Diagnosis can be confirmed by raised levels of dATP and reduced S-adenosyl homocysteine hydrolase SAHH activity in red cells and elevated amounts of deoxyadenosine in urine.

Health care resources for this disease Expert centres Diagnostic tests 46 Patient organisations 36 Orphan drug s 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 dexaminasa.

Disease definition Adenosine monophosphate AMP deaminase deficiency is a metabolic disorder for which two forms have been described.

Summary and related texts. Unfortunately, there is no medical cure for this disorder. The extraimmune manifestations are caused by toxic levels of purine metabolites that result from the deficiency of ADA.
