Resumen

Severe combined immunodeficiency (SCID) comprises a heterogeneous group of genetic disorders, with numerical and functional defects of both T and B lymphocytes. The most common form of SCID in humans, accounting for about 40% to 50% of all cases, is characterized by lack of circulating T (and usually also NK) cells, with a normal or increased number of B lymphocytes (T⁻B⁺ SCID).^{5 Buckley R.H., Schiff R.I., Schiff S.E. , y al.

Functional activation of Jak1 and Jak3 by selective association with IL-2 receptor subunits Science 1994 ; 266 : 1045

Mutations of the IL2RG gene that affect interaction between the γ_c and JAK3 also cause SCID.^{42 Russell S.M., Johnston J.A., Noguchi M. , y al.

Based on these data, it was hypothesized and then demonstrated in three unrelated patients, that mutations of the JAK3 gene are responsible for autosomal recessive T⁻B⁺ SCID in humans.^{27 Macchi P., Villa A., Giliani S. , y al.

During recent years, additional patients with SCID caused by JAK3 deficiency have been identified^{3 Bozzi F., Lefrano G., Villa A. , y al.

Finally, the potential for gene therapy to correct this disorder has been successfully investigated in the murine knock-out model^{7 Bunting K.D., Flynn K.J., Riberdy J.M. , y al.
