A rare genetic disease that manifests in childhood or early adolescence with a combination of chronic mucocutaneous candidiasis, hypoparathyroidism and autoimmune adrenal failure. The first manifestation of the disease (usually candidiasis) occurs in childhood with other manifestations appearing progressively. The most common autoimmune endocrine involvement is hypoparathyroidism (79-96% of cases). Adrenal failure most often manifests with concurrent mineralocorticoid and glucocorticoid deficiency (78% of cases). The disease is caused by mutations of the AIRE gene (21q22.3) coding for the AIRE transcription factor, which is involved in immune tolerance mechanisms and contributes to the negative selection of autoreactive T lymphocytes in the thymus, lymph nodes and spleen. Transmission is autosomal recessive. componente obsoleto (metadato fundacional)
