Abstract

Purpose: Autoimmune polyendocrine type 1 (APS-1) is a complex inherited autosomal recessive disorder. Classically, it appears within the first decade of life followed by adrenocortical insufficiency, mucocutaneous candidiasis, Addison's disease, and hypoparathyroidism. The clinical phenotype of APS-1 varies depending upon mutations in the autoimmune regulator gene (AIRE) on chromosome 21q22.3. Methods: In this study, we performed Sanger sequencing ofAIRE in Iranian patients to identify different variants and probable new mutations corresponding to a clinical diagnosis of APS-1. Results: After analyzing 14AIRE exons, we detected a novel insertion mutation in exon 2 in a patient who presented with severe APS-1, Lys50AsnfsX168. Furthermore, the known mutations in AIRE, including Arg139X, Arg257X, and Leu323SerfsX51, were detected in enrolled patients. Discussion: According to our results, sequencing analysis ofAIRE provides a useful screening method to diagnose patients with incomplete or unusual clinical presentations of APS-1.
