TLDR APS-1 in Italy shows diverse AIRE mutations and various autoimmune issues.

Autoimmune Polyglandular Syndrome type 1 (APS-1) is a rare inherited disease caused by AIRE gene mutations, characterized by chronic mucocutaneous candidiasis, chronic hypoparathyroidism, and Addison’s disease. In a survey of 158 Italian patients (103 females, 55 males) over an average follow-up of 23.7 years, 93% initially presented with one or more components of the classical triad. By the end of the follow-up, the prevalence of various autoimmune conditions was documented, including 24% with alopecia. The study found a high prevalence of IFNωAbs (91.1%) and identified several AIRE mutations, with R139X being the most common (21.3%). The overall mortality rate was 14.6%. APS-1 in Italy is marked by diverse AIRE mutations and a range of autoimmune manifestations.
