Autoimmune cytopenias predominated in T-cell defects, including hypomorphic RAG and CD3γ 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. This evidence concerns the gene LRBA and hyperinsulinemic hypoglycemia, familial, 4.
