Description
Severe combined immunodeficiency (SCID) comprises a heterogeneous group of monogenic disorders that result in early-onset severe infections by a range of pathogens (such as bacteria, viruses and fungi). Typically, patients with SCID have a severe defect in T-cell differentiation, along with direct or indirect impairment of B-cell development and function. Adenosine deaminase (ADA) deficiency accounts for about half of the autosomal recessive forms of SCIDs. It is one of the most severe immunodeficiencies and is associated with severe depletion of B cells, T cells, and NK cells. V(D)J- recombination deficiency caused by defects in recombinase-activating gene 1 (RAG1), RAG2 and Artemis (DCLRE1C) leads to a T-B-SCID phenotype that is characterized by an arrest of B- and T-cell maturation at the stage of pro-B and pre-T cells, respectively, whereas natural killer (NK)-cell maturation is not affected. V(D)J recombination generates the diversity of B- and T-cell primary immune repertoires.
