However, many patients develop non-triad manifestations years earlier, delaying recognition and care. In 2016, we proposed expanded diagnostic criteria incorporating 3 early clinical manifestations \u2014 APECED rash, autoimmune enteritis, and enamel hypoplasia \u2014 based on observations in 35 North American patients. Here, we provide further support for the clinical utility of these expanded diagnostic criteria in independent cohorts of 57 American and 12 European patients enrolled in a prospective natural history study at the NIH. Across all cohorts, the expanded diagnostic criteria decreased the time to diagnosis by half relative to the classic diagnostic criteria. Patients exhibited an enrichment of early non-endocrine autoimmune manifestations, underscoring disease heterogeneity and the potential for developing organ-specific autoimmunity before endocrine failure. These findings demonstrate the clinical utility of the expanded APECED diagnostic criteria and support the notion that their adoption might enable earlier disease recognition and timely immunomodulatory therapy to improve long-term outcomes.<\/jats:p>","DOI":"10.1172\/jci.insight.203021","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T18:01:12Z","timestamp":1784656872000},"source":"Crossref","is-referenced-by-count":3,"title":["Performance
