Inherited ITK deficiency shows incomplete penetrance for severe EBV disease and can underlie severe tuberculosis due to insufficient IFN-γ production by innate-like adaptive (Vδ2+ γδ T and MAIT) and purely adaptive αβ T lymphocytes. Inborn errors of IFN-γ immunity can underlie tuberculosis (TB). We report three patients from two kindreds without EBV viremia or disease but with severe TB and inherited complete ITK deficiency, a condition associated with severe EBV disease that renders immunological studies challenging. They have CD4+ αβ T lymphocytopenia with a concomitant expansion of CD4−CD8− double-negative (DN) αβ and Vδ2− γδ T lymphocytes, both displaying a unique CD38+CD45RA+T-bet+EOMES− phenotype. Itk-deficient mice recapitulated an expansion of the γδ T and DN αβ T lymphocyte populations in the thymus and spleen, respectively. Moreover, the patients’ T lymphocytes secrete small amounts of IFN-γ in response to TCR crosslinking, mitogens, or forced synapse formation with autologous B lymphocytes. Finally, the patients’ total lymphocytes secrete small amounts of IFN-γ, and CD4+, CD8+, DN αβ T, Vδ2+ γδ T, and MAIT cells display impaired IFN-γ production in response to BCG. Inherited ITK deficiency undermines the development and function of various IFN-γ–producing T cell subsets, thereby underlying TB.
