Distinct interferon signatures and cytokine patterns define additional systemic autoinflammatory diseases

CONCLUSIONS In patients with elevated IRG-S, we identified characteristic clinical features and 3 additional autoinflammatory diseases: IL-18–mediated PAP and recurrent MAS (IL-18PAP-MAS), NEMO deleted exon 5–autoinflammatory syndrome (NEMO-NDAS), and SAMD9L-associated autoinflammatory disease (SAMD9L-SAAD). The IRG-S expands the diagnostic armamentarium in evaluating USAIDs and points to different pathways regulating IRG expression.TRIAL REGISTRATION ClinicalTrials.gov NCT02974595.FUNDING The Intramural Research Program of the NIH, NIAID, NIAMS, and the Clinical Center.
