Autoimmune features were documented in 163 patients (19.8%), including 26 (3.2%) with concurrent autoinflammatory findings, whereas isolated autoinflammatory conditions were observed in 54 patients (6.5%). A broad spectrum was observed, with autoimmune cytopenias predominating (11.4%), followed by gastrointestinal (7.8%), rheumatologic (5.3%), and endocrine (3.4%) disorders. Immune dysregulation was a recurrent theme across all IEI categories, with a distinct, disease-specific, clustering of autoimmunity and autoinflammation. Autoimmune cytopenias predominated in T-cell defects, including hypomorphic RAG and CD3\u03b3 deficiencies; Inflammatory bowel disease (IBD) was enriched in ARPC1B, DOCK8, and CD55 deficiencies, as well as in chronic granulomatous disease (CGD); endocrine autoimmunity, while a cardinal feature of APECED and IPEX, also characterized STAT1 gain-of-function; inflammatory granulomatous lung disease was a consistent feature in LRBA deficiency; and granulomatous inflammation, whether confined to the lungs or extending to other organs, was prominent in common variable immunodeficiency.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Recognition of clustering patterns, particularly autoimmune cytopenias, IBD, and endocrine autoimmunity, has direct clinical implications. These manifestations should be regarded as red flags, guiding targeted evaluation and genetic testing.
