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.

InfancyNeonatal ICD 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.

Approximately equal proportions of the patients first develop symptoms during childhood, deticiencia, or as young or older adults. Unfortunately, there is no medical cure for this disorder. The vast majority of patients suffer from post-exercise symptoms: 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. The disorder exclusively affects skeletal muscle.

The extraimmune manifestations are caused by toxic levels of purine metabolites that result from the deficiency of ADA.

Survival rates after allogenic hematopoietic stem cell transplantation or gene therapy are high. This mutation creates an early stop codon thus preventing the synthesis of an enzymatically active protein.

Diagnostic methods 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.

The most common form presents in deeaminasa with severe and recurrent opportunistic infections including respiratory tract infections and candidiasisfailure to thrive, and usually results in early death.

Symptoms improve with administration of D-ribose. Smooth muscle or other organs are not affected as the disorder is associated with a specific lack of skeletal muscle adenylate adehosina activity. However, the effects of this sugar are only short-tem and it has no beneficial effect during subsequent days.

Clinical description The vast majority of patients suffer from post-exercise symptoms: The vast majority of patients with this disease are homozygous for the nonsense CT mutation in the AMPD1 adenosine monophosphate deaminase 1 gene.

Disease definition Adenosine monophosphate AMP deaminase deficiency is a metabolic disorder for which two forms have been described. The deficiency disrupts the purine nucleotide deficuencia, and thus muscle energy production. Diagnostic methods The diagnosis is based on histochemical staining or biochemical analysis of a muscle biopsy showing a lack of muscle deficisncia deaminase activity, or on molecular identification of the disease-causing mutation.
