This site provides users with simple animations accompanied by explanatory text outlining the use of gene therapy in a particular immunodeficiency case study. It includes an animation of gene therapy for the genetic immune deficiency called SCID-X1. Children with this disease have a defective gene. The animation begins with an explanation of the genetic and phenotypic characteristics of severe combined immunodeficiency (SCID) including the region of mutation within the DNA and the resulting effect on the development of immune responsive cells. The animation provides a simplified portrayal of the theoretical mechanism of gene therapy and its implementation in the treatment of this particular disorder. The animation concludes with a sobering look at the results of the case study and the possible complications that gene therapy may pose. It provides a balanced portrayal of the positive possibilities of gene therapy with the negative risks involved in this relatively new treatment. This is a good site for classroom or individual use.
