Overview
Autoimmune polyendocrine syndrome type 1 (APS-1), also known as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED), Whitaker syndrome,[1] or candidiasis-hypoparathyroidism-Addison's disease-syndrome,[2] is a subtype of autoimmune polyendocrine syndrome, in which multiple endocrine glands dysfunction as a result of autoimmunity. It is a genetic disorder inherited in autosomal recessive fashion due to a defect in the AIRE (Auto immune regulator) gene which is located on chromosome 21 and normally confers immune tolerance.

Its main features include:[citation needed]
- A mild immune deficiency, leading to persistent mucosal and cutaneous infections with candida yeasts. There is also decreased function of the spleen (hyposplenism).
- Autoimmune dysfunction of the parathyroid gland (leading to hypocalcaemia) and the adrenal gland (Addison's disease: hypoglycemia, hypotension and severe reactions in disease).
- Other disease associations are:
- hypothyroidism
- hypogonadism and infertility
- vitiligo (depigmentation of the skin)
- alopecia (baldness)
- malabsorption
- pernicious anemia
- chronic active (autoimmune) hepatitis
