Autoimmune Polyendocrinopathy Candidiasis-Ectodermal Dystrophy (APECED) is a rare disease that starts in childhood. It happens when a gene called AIRE does not work properly. AIRE’s normal job is to “teach” the immune system, inside the thymus, to ignore the body’s own tissues. When AIRE fails, the immune system can attack many organs (autoimmunity). The most common problems are a long-lasting yeast infection of the skin, mouth, and nails (chronic mucocutaneous candidiasis), low blood calcium from hypoparathyroidism, and primary adrenal insufficiency (Addison’s disease). Many people also have skin, dental, liver, stomach, and reproductive gland problems. APS-1 is usually inherited in an autosomal recessive way (two faulty AIRE copies), though milder “non-classic” disease from certain dominant AIRE variants also exists. RUPress+3NCBI+3PMC+3

APS-1 (also called APECED) is a rare, inherited immune system disease that usually starts in childhood. It most often includes a “classic triad”: chronic mucocutaneous candidiasis (recurrent yeast infections of the mouth/skin), hypoparathyroidism (low parathyroid hormone causing low calcium), and primary adrenal insufficiency/Addison’s disease (the adrenal glands cannot make enough cortisol ± aldosterone). People may also develop other autoimmune problems (like hepatitis, intestinal problems, dental enamel defects, alopecia, keratitis, and asplenia). Diagnosis is clinical plus genetic testing for AIRE gene variants. Treatment focuses on replacing missing hormones, preventing adrenal crisis, and controlling candidiasis and other autoimmune issues.

Other names

• APECED (Autoimmune Polyendocrinopathy–Candidiasis–Ectodermal Dystrophy)

• Autoimmune polyglandular syndrome type 1 (APS-1)

• Polyglandular autoimmune syndrome type 1 (PGA-I)
  These terms describe the same condition caused by AIRE gene defects. Immune Deficiency Foundation+1

Types

1. Classic APS-1 (autosomal recessive AIRE deficiency). Childhood onset. “Triad” of chronic mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency; many have ectodermal changes (dental enamel defects, nail changes). NCBI+1

2. Non-classic / dominant AIRE disease. Some people with a single (heterozygous) dominant-negative AIRE variant develop a later-onset, milder, or different set of autoimmune features; CMC may be absent. These cases broaden the spectrum beyond pure recessive disease. RUPress+2JCI+2

3. Phenotype-focused subsets (used in practice).

   • CMC-predominant early childhood form. Recurrent oral/skin Candida infections often appear first. Frontiers

   • Endocrine-predominant form. Hypoparathyroidism and/or Addison disease lead the picture. NCBI

   • Cytokine-autoantibody–predominant form. High-titer autoantibodies to type I interferons (and to IL-17/IL-22) are characteristic and now used diagnostically. PLOS+1

Causes

Truth in a nutshell: the root cause is pathogenic variants in the AIRE gene. The rest of this list shows the detailed mechanisms and modifiers that explain how a single gene defect produces many problems and why people look different from each other.

1. Biallelic AIRE loss-of-function (autosomal recessive). The defining cause of classic APS-1; hundreds of variants reported. ScienceDirect+1

2. Failure of central T-cell tolerance in the thymus. Without working AIRE, tissue-restricted antigens are not displayed; self-reactive T cells escape. PMC

3. Defective medullary thymic epithelial cells (mTECs). AIRE orchestrates gene expression in mTECs; its loss alters antigen display and thymic architecture. PMC

4. High-affinity autoreactive T cells in the periphery. These cells survive selection and can attack organs. PMC

5. Autoantibodies to type I interferons (IFN-α/ω). Highly specific for APS-1 and contribute to infection susceptibility and immune dysregulation. PLOS

6. Autoantibodies to IL-17/IL-22 pathways. These impair mucosal antifungal immunity and help explain chronic Candida infections. Frontiers

7. Dominant-negative AIRE variants. Certain heterozygous mutations can poison the AIRE complex, causing non-classic APS-1. RUPress+1

8. Founder mutations in specific populations. High local frequencies lead to clusters (e.g., Finnish, Sardinian, Iranian Jewish cohorts). Oxford Academic

9. Modifier genes and HLA background. Genetic background can shape which organs are targeted and when. PMC

10. Environmental triggers (infections). Infections may unmask or amplify organ autoimmunity in genetically primed individuals. PMC

11. Epithelial/ectodermal vulnerability. Ectodermal structures (nails, enamel) are often involved; exact pathways relate to immune-epithelial interactions. NCBI

12. Mucosal immune defects. Th17 axis disruption weakens antifungal defense at skin and mucosa. Frontiers

13. Breakdown of B-cell tolerance. Autoreactive B cells produce diverse organ-specific autoantibodies (e.g., anti-21-hydroxylase, anti-parietal cell). NCBI

14. Immune endocrine crosstalk. Hormone-secreting cells are frequent immune targets (parathyroid, adrenal, gonads). NCBI

15. Age-dependent penetrance. Different components appear at different ages (CMC often first; endocrinopathies later). Oxford Academic

16. Sex-related influences. Some autoimmune components show female predominance (e.g., ovarian failure). NCBI

17. Chronic inflammation and tissue damage cycles. Ongoing autoreactivity sustains organ injury over time. PMC

18. Diagnostic delay. Missed early signs allow disease to evolve unchecked; this “cause” of severity is clinical, not genetic. Nature

19. Nutritional sequelae of endocrine failure. Hypoparathyroidism and adrenal insufficiency alter calcium and electrolyte balance, worsening symptoms. NCBI

20. Autoimmune liver and gut involvement. Secondary organ autoimmunity (autoimmune hepatitis, pernicious anemia) broadens disease impact. NCBI

6. Eye irritation or dryness. Keratoconjunctivitis can cause red, painful, or gritty eyes. NCBI

7. Stomach problems. Nausea, anemia, or B12 deficiency from autoimmune gastritis/pernicious anemia. NCBI

8. Liver issues. Elevated liver enzymes or autoimmune hepatitis causing fatigue and jaundice in some. NCBI

9. Early ovarian failure. Irregular periods, infertility, or menopausal symptoms in young women. NCBI

10. Testicular dysfunction (less common). Low testosterone symptoms in males. NCBI

11. Thyroid disease. Some develop hypothyroidism with weight gain, cold intolerance, and tiredness. NCBI

12. Type 1 diabetes (in a minority). Thirst, frequent urination, and weight loss can occur. NCBI

13. Asplenia/splenomegaly or recurrent infections. Immune dysregulation raises infection risks. NCBI

14. Joint and muscle pains. Non-specific autoimmune inflammation may cause aches. PMC

15. Psychological stress and quality-of-life impact. Chronic symptoms, hospital visits, and dietary restrictions affect daily life. Nature

Immunity-booster / regenerative / stem-cell” drugs

There are no proven stem-cell or “regenerative” cures for APS-1 at this time. Care is mainly hormone replacement and targeted immunomodulation. Experimental JAK-inhibition is being studied for interferon-driven inflammation. The following entries explain the landscape so you can discuss options safely with your specialist. New England Journal of Medicine

1. JAK inhibitors (e.g., baricitinib) — Mechanism: block JAK-STAT signaling downstream of interferons to reduce tissue inflammation. Dosing is specialist-led; monitor CBC, LFTs, lipids, and infection risk. Not standard of care; reserved for select, refractory cases in centers with expertise. New England Journal of Medicine

2. Targeted biologics for organ autoimmunity (case-by-case) — Agents like rituximab (B-cell depletion) or anti-TNF may be used for specific organ disease under subspecialist guidance when conventional therapy fails. Risks: serious infection, infusion reactions; benefits limited to select scenarios. Evidence in APS-1 is limited. PMC
