Whether the therapeutic gene delivered to Ashanti replaced the defective copy of the ADA gene at the time of the first successful trial of gene therapy. Introduction: The FDA approved the first human gene therapy trial in 1990. This therapy started with the treatment of a young girl named Ashanti De Silva. She has a heritable disorder called adenosine deaminase severe combined immunodeficiency (ADA-SCID). SCID is a hereditary disease that is a result of many genetic mutations, such as the abnormal development of B and T cells.
