Autoimmune Polyglandular Syndrome Type 1: a case report.


ABSTRACT: BACKGROUND:Mutations of the autoimmune regulator gene (AIRE), located on chromosome 21q22.3, are recognized as the cause of a rare monogenic organ-specific autoimmune disorder called autoimmune polyglandular syndrome type 1 (APS-1). Three major components of this syndrome include chronic mucocutaneous candidiasis (CMC), hypoparathyroidism, and adrenocortical failure. CASE PRESENTATION:We report a 19-year-old girl, who was born in an Iranian Muslim family with a clinical diagnosis of APS-1. To identify the causative mutation, a direct sequencing of the entire AIRE gene sequence was performed by Sanger sequencing method. Three distinct variants were discovered, including c.1095?+?2?T?>?A, c.1197?T?>?C (rs1800521) and c.1578?T?>?C (rs1133779), in intron 9, exons 10 and 14 of the AIRE gene, respectively. CONCLUSIONS:To the best of our knowledge, this is the first report of an Iranian Muslim APS-1 patient with combination of these variations. In addition, the effect of c.1095?+?2?T?>?A mutation on AIRE mRNA expression was reported for the first time. This study expands the diversity of variants that could cause APS-1. More genetic studies are required to determine the exact frequency of these variants and their diagnostic significance.
