[Type 1 polyglandular autoimmune syndrome associated with C322fsx372 mutation]

Area of Science:

• Endocrinology
• Immunology
• Genetics

Background:

• Polyglandular autoimmune syndromes (PAS) are rare autoimmune disorders characterized by the coexistence of endocrine and non-endocrine conditions.
• Type 1 PAS typically presents with chronic mucocutaneous candidiasis, hypoparathyroidism, and adrenal insufficiency.

Observation:

• A case study detailing a patient with the characteristic clinical sequence of Type 1 PAS and additional manifestations.
• Molecular analysis revealed a homozygous mutation (C322fsX372) in the autoimmunity regulator gene (AIRE).

Findings:

• The study highlights the autosomal recessive inheritance pattern of PAS, linked to mutations in the AIRE gene.
• The AIRE gene encodes a protein critical for regulating autoimmunity and immune function.

Implications:

• Diagnostic criteria for PAS require at least two major clinical manifestations, with one sufficient for relatives.
• Timely diagnosis and comprehensive management of each manifestation are essential to mitigate high morbidity and mortality rates and improve quality of life.
