Autoimmune polyendocrinopathy syndrome type 1

Autoimmune polyendocrine syndrome type 1 (APS1) is a multiorgan autoimmune disorder caused by mutations in AIRE, the autoimmune regulator gene. It is characterized by multiple autoimmune endocrinopathies, chronic mucocutaneous candidiasis, and ectodermal dystrophies. APS1 has been reported to be inherited in an autosomal recessive manner. However, a novel mutation was recently described to be inherited in a dominant fashion.
