Complexes of adenosine deaminase with two potent inhibitors: The longer the disorder goes unrecognized, the more immune function deteriorates and desaminaea more likely are chronic sequelae of recurrent infection.

Deifciencia diarrhea, extensive dermatitis, recurrent pneumonia, and other life-threatening illnesses caused by opportunistic infections occur frequently. Most known Dedaminasa pathogenic variants have been discovered through research into the relationship of genotype to phenotype [ Hirschhorn et alSantisteban et alArredondo-Vega et alOzsahin et al ]. Prognosis Prognosis depends on the severity of the disease.

Pulmonary alveolar proteinosis in patients with adenosine deaminase deficiency. Diagnosis, treatment and long-term follow up of patients with ADA deficiency: All racial and ethnic groups are affected.

See Molecular Genetics for information on allelic variants detected in this gene.

Management Evaluations Following Initial Diagnosis To establish the extent of disease and needs in an individual diagnosed with adenosine deaminase ADA deficiency, the following evaluations are recommended, some of which may be performed as part of the diagnostic evaluation: Contribution of genotype to phenotype.


No further modifications are allowed. A panel that includes ADA and other genes of interest see Differential Diagnosis may also be considered. Most deaths occurred during the first six months of treatment, with the majority in the first month due to life-threatening infections present at diagnosis.

This section is not meant to address all personal, cultural, or ethical issues that individuals may face or to substitute for consultation with a genetics professional.

In individuals with biochemically documented ADA deficiency. Assessment of humoral immune function by measuring serum immunoglobulins and the titer of specific antibodies related to infections and immunizations.

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. Review Beta-Thalassemia Origa R. Adenosine deaminase ADA deficiency should be suspected in individuals with the following newborn screening results, clinical findings by ageand supportive laboratory findings.

The different extent of B and T cell immune reconstitution after hematopoietic stem cell transplantation and enzyme replacement therapies in SCID patients with adenosine deaminase deficiency. Hematopoietic stem-cell transplantation for the treatment of severe combined immunodeficiency. Defiiencia recording back on. It is appropriate to offer genetic counseling including discussion of potential risks to offspring and reproductive options to young adults who are affectedare carriers, or are at risk of being carriers.

October 3, ; Last Update: Lentiviral vectors for the treatment of primary immunodeficiencies. For other genetic causes of these phenotypes see Differential Diagnosis.


Non-infectious lung disease appears to occur more frequently in individuals with ADA deficiency than with other genetic forms of SCID [ Booth et al ]. Gene therapy for severe combined immunodeficiency. Annual or more frequent evaluation of lymphocyte counts, serum immunoglobulin levels, and various in vitro tests of cellular and humoral immune function i. Gene therapy for adenosine deaminase-deficient severe combined immune deficiency: Curr Opin Mol Ther.

Methods that may be used include: Allergies and elevated serum concentration of IgE are common. Spontaneous in vivo reversion of an inherited mutation in the Wiskott-Aldrich syndrome.

Adenosina desaminasa

A system for ranking the severity of genotypes has been proposed based on these data and the potential of other alleles to provide ADA activity. For these individuals, alternative therapies can be considered: Mode of Inheritance Adenosine deaminase ADA deficiency is inherited in deficiencoa autosomal recessive manner.

Molecular genetic testing if the pathogenic variants in the family are known. Overall, approximately half of these secondary transplants have been successful [ HershfieldGaspar et al ].

Experimental gene therapy for ADA-deficient SCID employing gamma retroviral vectors has been desamminasa clinical investigation for more than 20 years [ Engel et alCavazzana-Calvo et al ]. A rare malignant skin tumor, dermatofibrosarcoma protuberans DFSP has been identified in several individuals with ADA dwsaminasa [ Kesserwan et al ].
