WebThe α chain binds IL-2 with low affinity, the combination of β and γ together form a complex that binds IL-2 with intermediate affinity, primarily on memory T cells and NK cells; and all three receptor chains form a complex that binds IL-2 with high affinity (Kd ~ 10 −11 M) on activated T cells and regulatory T cells. WebFlow cytometry may reveal the lack of common gamma chain (CD132) expression on the surface of lymphocytes. However, certain missense mutations can lead to expression of non-functional protein on lymphocytes. As a result, the presence of CD132 expression does not rule out X-linked SCID. 5. Sequencing of the IL2RG gene can confirm the diagnosis. 6.

The most common treatment for SCID is bone marrow transplantation, which has been very successful using either a matched related or unrelated donor, or a half-matched donor, who would be either parent. The half-matched type of transplant is called haploidentical.
