Severe combined immunodeficiency SCID due dfficiencia 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.

Both males and females are affected. The most common form presents in infancy with severe and recurrent opportunistic infections including respiratory tract infections and candidiasisfailure to thrive, and usually results in early death.

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.

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

Diagnosis deamknasa 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.

Diagnosis can be confirmed by raised levels of dATP and reduced S-adenosyl homocysteine hydrolase SAHH adenosuna in red cells and elevated amounts of deoxyadenosine in urine. 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.

Prognosis depends on the severity of the disease. Survival rates after allogenic hematopoietic stem cell transplantation or gene therapy are high.
