NCIt definition : T cells harvested from a patient with adenosine deaminase (ADA) deficiency and transduced
with a vector containing the gene for ADA. ADA catalyzes the hydrolysis of adenosine
to inosine; ADA deficiency causes a form of severe combined immunodeficiency (SCID).
Following genetic modification, the T cells are returned to the patient, where they
produce functional ADA. ADA-transduced T cells have been shown to improve immune function
in individuals with ADA deficiency. (NCI04);
