Autoimmune polyglandular syndrome type 1 (APS-1), also called autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), is a genetic immune disorder. This disorder has a diverse range of symptoms, including autoimmunity against different organs and an increased susceptibility to candidiasis, a fungal infection caused by Candida yeast.

The syndrome is caused by mutations in the autoimmune regulator (AIRE) gene. NIAID researchers are exploring how AIRE mutations impact the function of cells by studying people with APS-1 (APECED), as well as using mouse models of AIRE deficiency. With a better understanding of how these mutations affect the immune system and other cells in the body, researchers hope to uncover promising therapeutic targets to prevent and treat persistent candidiasis and autoimmune disorders.

By evaluating a large group of people from North and South America with this rare immune disorder, NIH scientists in 2016 re-defined the clinical features and diagnostic criteria for APS-1 (APECED). The FUNGI Study, a natural history study following adults and children with APS-1 (APECED), began in 2011 and is currently enrolling eligible participants.
