Genetic Basis of Immunodeficiency

Severe Combined Immunodeficiency Clinical Trial

Official title: The Determination of Genetic Basis Of Immunodeficiency

Status Recruiting

Clinical Trial Summary

This study will examine the role of hereditary factors in different forms of severe combined immunodeficiency (SCID).

Patients with immunodeficiencies may be eligible for this study. Candidates include:

• Patients with diminished numbers of T cells or NK cells or both, or

• Patients with normal T cell and NK cell numbers but diminished T cell, B cell, or NK cell function.

Relatives of patients will also be studied.

Participants will have blood samples collected for genetic analysis in studies related to SCID at the National Institutes of Health and other institutions.

Clinical Trial Description

The goal of this project is to identify the genetic basis of new forms of inherited immunodeficiency. The particular focus relates to cytokines such as IL-2, IL-4, IL-7, IL-9, IL-15, and IL-21 that share the common cytokine receptor (Gamma) chain, (Gamma c), and to molecules that are important for signaling or gene regulation in response to these cytokines, although other causes of inherited immunodeficiency are also encompassed. ;
