Severe combined immunodeficiency conditions are devastating disorders of adaptive immunity. Although these diseases were initially treated by transplantation of allogeneic hematopoietic stem cells, the past 20 years has shown that these conditions are correctable by gene therapy. 
Gene therapy finds its niche
Gene therapy is finally poised to make a contribution to the treatment of debilitating, highly penetrant genetic diseases that have proved intractable to other regimens.
A single‐center study of hematopoietic stem cell transplantation for primary immune deficiencies (PIDD)
TLDR
A single‐center study of hematopoietic stem cell transplantation for primary immune deficiencies (PIDD) and its effects on survival and quality of life is presented. Expand
Gene therapy for Wiskott-Aldrich Syndrome—Long-term reconstitution and clinical benefits, but increased risk for leukemogenesis
TLDR
Wiskott-Aldrich-Syndrome is a rare X-linked recessive disease caused by mutations of the WAS gene that is characterized by immunodeficiency, autoimmunity, low numbers of small platelets and a high risk of cancer, especially B cell lymphoma and leukemia. Expand
Strategies for retrovirus-based correction of severe, combined immunodeficiency (SCID).
TLDR
Design of vectors in which the enhancer element of retroviral LTR has been deleted and an internal promoter added (self-inactivated vectors) could provide both safe and efficient gene transfer as being presently tested. Expand
Haematopoietic stem cell transplantation for SCID patients: where do we stand?
TLDR
The complete absence of the T cell compartment in SCID prompted the development of haploidentical, parental HSCT for the many patients who do not have a human leucocyte antigen (HLA)‐identical sibling. Expand
Gene Therapy for Primary Immunodeficiencies
TLDR
Clinical trials for SCID-X1, Wiskott-Aldrich syndrome, and recently ADA-SCID showed sustained engraftment of gene-corrected cells, restored immune function, and general improvement of clinical condition, with a positive safety profile, so continuous monitoring will be important to confirm long-term safety and efficacy. Expand
Gene therapy for primary immunodeficiencies
TLDR
Results of recent trials performed for several forms of PID suggest that their use is both safe and efficacious, and it is anticipated that their application to the treatment of many more life threatening PID will be developed over the coming years. Expand
Homologous recombination‐based gene therapy for the primary immunodeficiencies
  • M. Porteus
  • Biology, Medicine
  • Annals of the New York Academy of Sciences
  • 2011
TLDR
The development of nuclease‐stimulated, homologous recombination‐based approaches as a novel gene therapy strategy for the primary immunodeficiencies is discussed. Expand
Hematopoietic stem cell expansion and gene therapy.
TLDR
Some of the current limitations of HSC gene therapy could be overcome by combining novel HSC expansion strategies with gene therapy, as well as the opportunities presented by implementing ex vivo expansion of gene-modified HSC. Expand
Update on gene therapy for adenosine deaminase-deficient severe combined immunodeficiency
TLDR
In comparison with SCID-X1, ADA-SCID gene therapy presents a better safety profile and engraftment of multilineage transduced stem/progenitor cells, thanks to the use of nonmyeloablative preconditioning. Expand

How I treat ADA deficiency.
TLDR
The choice between ERT, MUD transplant, or GT is difficult and dependent on several factors, including accessibility to the different modalities, response of patients to long-term ERTs, and the attitudes of physicians and parents to the short- and potential long- term risks associated with different treatments.
