Immunodeficiency can occur in CHARGE syndrome, with immunophenotypes including reduction in T-cell counts, combined T-B cell defects rarely requiring antibiotic prophylaxis or immunoglobulin replacement, and severe combined immunodeficiency, which is fatal without immune reconstitution. However, the prevalence of immunodeficiency in CHARGE syndrome remains unclear with few prospective studies. In this review, we examine the existing literature covering immunodeficiency associated with CHARGE syndrome, compare these with immunodeficiencies reported in 22q11.2 deletion syndrome (a condition that shares many phenotypic characteristics with CHARGE syndrome) and suggest future research priorities.
