Gene Therapy for X-linked Severe Combined Immunodeficiency (SCID-X1)

Summary

X-linked severe combined immunodeficiency (SCID-X1) is an inherited disorder that results in failure of development of the immune system in boys. This trial aims to treat SCID-X1 patients using gene therapy to replace the defective gene.
