Severe Combined Immunodeficiency: Group of rare congenital disorders characterized by impairment of both humoral and cell-mediated immunity, leukopenia, and low or absent antibody levels. It is inherited as an X-linked or autosomal recessive defect. Mutations occurring in many different genes cause human Severe Combined Immunodeficiency (SCID).

Severe infections were defined as those that required hospitalization or those that prolonged hospitalization. The rate of infection was estimated as number of severe infections over person-years of observation (free from severe infections) before and after treatment administration. The first 3 months after gene therapy were not considered in the post-gene therapy analysis, because all subjects were hospitalized during this period. (NCT00598481)
Timeframe: Before Treatment and 3-months post-treatment up to 3 years
