An alternative gene therapy for ADA-SCID may utilize recombinant adeno-associated virus vectors in vivo, with numerous target tissues, to foster ectopic expression and secretion of adenosine deaminase. These groundbreaking gene therapies represent a revolution in clinical medicine, but come with several challenges, including the risk of insertional mutagenesis. Gene therapies for ADA-SCID over nearly two decades have exclusively involved retroviral vectors targeted to lymphocytes and hematopoetic progenitors. The standard of care for adenosine deaminase deficient severe combined immune deficiency (ADA-SCID) includes enzyme replacement therapy or bone marrow transplantation. Adenosine deaminase deficiency fosters a rare, devastating pediatric immune deficiency with concomitant opportunistic infections, metabolic anomalies and multiple organ system pathology.
