240300 | OMIM | Autoimmune polyendocrine syndrome 1, with or without reversible metaphyseal dysplasia (APS1) | A rare disease characterized by the combination of chronic mucocutaneous candidiasis, hypoparathyroidism and Addison disease. Symptoms of mucocutaneous candidiasis manifest first, followed by hypotension or fatigue occurring as a result of Addison disease. APS1 is associated with other autoimmune disorders including diabetes mellitus, vitiligo, alopecia, hepatitis, pernicious anemia and primary hypothyroidism. The disease is caused by variants affecting the gene represented in this entry. Most of the mutations alter the nucleus-cytoplasm distribution of AIRE and disturb its association with nuclear dots and cytoplasmic filaments. Most of the mutations also decrease transactivation of the protein. The HSR domain is responsible for the homomultimerization activity of AIRE. All the missense mutations of the HSR and the SAND domains decrease this activity, but those in other domains do not. The AIRE protein is present in soluble high-molecular-weight complexes. Mutations in the HSR domain and deletion of PHD zinc fingers disturb the formation of these complexes (PubMed:14974083). Heterozygous mutations within the PHD1 domain have dominant-negatif effects and cause organ-specific autoimmune diseases (PubMed:26084028). Patients harbor extremely high-affinity, neutralizing autoantibodies, particularly against specific cytokines such as type I interferons which could protect them from some types of autoimmune diseases, like type I diabetes (PubMed:27426947). |
