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

Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. The vast majority of patients with this disease are homozygous for the nonsense CT mutation in the AMPD1 adenosine monophosphate deaminase 1 gene. 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.
There is no evidence of muscular dystrophy or muscular wasting. Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. The vast majority of patients suffer from post-exercise symptoms: 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.
Adenosine monophosphate AMP deaminase deficiency is a metabolic disorder for which two forms have been described. Only comments written in English can be processed. Health care resources for this disease Expert centres Diagnostic tests 46 Patient organisations 36 Orphan drug s 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 1 Clinical signs adenosinna symptoms Publications in PubMed Other website s 8. The prevalence is unknown but several hundred patients with the disorder have been reported in case reports and patient series. Symptoms improve with administration of D-ribose.
The extraimmune manifestations are caused by toxic levels of purine metabolites that result from the deficiency of ADA. Prognosis Prognosis depends on the severity of the disease. For all other comments, please send your remarks via contact us.
The deficiency disrupts the purine nucleotide cycle, and thus muscle energy production.
Men and women are equally affected. Severe combined immunodeficiency SCID due to adenosine deaminase ADA deficiency is a form of SCID characterized by profound lymphopenia and very low immunoglobulin levels of all isotypes resulting in severe and recurrent opportunistic infections.
Prognosis depends on the severity of the disease.
After progression of the symptoms over the first few years, the clinical course usually stabilises. Etiology The vast majority of patients with this disease are homozygous for the nonsense CT mutation in the AMPD1 adenosine monophosphate deaminase 1 gene.

The documents contained in this web site are presented for information purposes only. Diagnostic methods The diagnosis is based on histochemical staining or biochemical analysis of a muscle adenozina showing a lack of muscle adenylate deaminase activity, or zdenosina molecular identification of the disease-causing mutation.
Prenatal diagnosis can be carried out through mutation analysis or measurement of enzyme activity in trophoblasts cultured from chorionic villus sampling or in cultured amniocytes.
Diagnosis is based on evidence of low or undetectable ADA activity in erythrocytes in combination with evidence of a marked reduction of T, B and NK cell counts when compared to age-matched healthy controls. Check this box if you wish to receive a copy of your message.
