This mutation creates an early stop dessminasa thus preventing the synthesis of an enzymatically active protein.

After progression of the symptoms over the first few years, the clinical course usually stabilises.

Genetic counseling Transmission is autosomal recessive. For all other comments, please send your remarks via contact us. 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.
There is no evidence of muscular dystrophy or muscular wasting. 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.
