| Description |
Overall, this work describes the largest cohort of patients with RAG mutations and an associated phenotype consisting of combined immunodeficiency and granulomatous lesions and/or autoimmunity (CID-G/AI). By using multiple methods (microarray, ELISA and multiplex bead technology), we have consistently identified a distinctive signature of anti-cytokine antibodies in patients with RAG-dependent immunodeficiencies, especially in those with CID-G/AI and a history of severe viral infections. These autoantibodies were not detected in a large panel of patients with other forms of primary immunodeficiency, and may therefore represent a novel biomarker panel of this condition. |
