    Severe combined immunodeficiency (ADA-SCID) caused by adenosine deaminase (ADA) deficiency is a rare and life-threatening primary immunodeficiency.


    Immune infection recently researchers examined the therapeutic effect of autologous in vitro lentiviral gene therapy for ADA-SCID is.


    Fifty ADA-SCID patients (30 from the United States and 20 from the United Kingdom) participated in the study, using autologous CD34+ hematopoietic stem and progenitor cells (HSPCs) to transduce a self-inactivating lentiviral vector encoding human ADA in vitro , The study was followed up for 24-36 months.
