Defective ADA disrupts (deoxy)adenosine deamination
Click the image above or here to open this pathway in the Pathway Browser
Normally in humans, adenosine and deoxyadenosine can be deaminated to inosine and deoxyinosine, catalyzed by ADA (adenosine deaminase). In the absence of ADA activity, however, accumulated nucleosides disrupt lymphoid cell function, leading to severe combined immunodeficiency (Hirschhorn et al. 1989, 1990).
