Bubble boy disease gets a gene fix: new trial offers hope
Disease control ENROLLING_BY_INVITATIONThis study tests a new gene therapy for X-linked severe combined immunodeficiency (X-SCID), a rare immune disorder. Doctors take a person's own stem cells, fix a faulty gene using a technique called base editing, and return the cells to the body. The goal is to rebuild the immune…

Gene therapy trial aims to fix 'Bubble Boy' disease in newborns
Disease control TerminatedThis study tests a gene therapy for infants with X-linked severe combined immunodeficiency (SCID-X1), a life-threatening condition where babies lack a working immune system. Researchers take the baby's own bone marrow stem cells, add a normal copy of the faulty gene using a lenti…
