Genes affected

AIRE (HGNC:360): (autoimmune regulator) This gene encodes a transcriptional regulator that forms nuclear bodies and interacts with the transcriptional coactivator CREB binding protein. The encoded protein plays an important role in immunity by regulating the expression of autoantigens and negative selection of autoreactive T-cells in the thymus. Mutations in this gene cause the rare autosomal-recessive systemic autoimmune disease termed autoimmune polyendocrinopathy with candidiasis and ectodermal dystrophy (APECED).

Polyglandular autoimmune syndrome, type 1 Pathogenic:6

Pathogenic, criteria provided, single submitter	clinical testing	Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego	Oct 31, 2017	The c.1265delC; p.Pro422LeufsTer58 variant has been reported previously in a patient with autoimmune polyendocrinopathy syndrome type 1 (AIRE); however, no additional variant was identified in that patient (Heino et al., 1999). The deletion causes a frameshift starting with codon Proline 422, changes this amino acid to a Leucine residue and creates a premature Stop codon at position 58 of the new reading frame, denoted p.Pro422LeufsX58. This pathogenic variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. Therefore, we consider this variant to be pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Oct 24, 2019	Variant summary: AIRE c.1265delC (p.Pro422LeufsX58) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant allele was found at a frequency of 2.2e-05 in 184258 control chromosomes (gnomAD). c.1265delC has been reported in the literature in individuals affected with Autoimmune Polyglandular Syndrome Type 1 (Heino_1999, Pearce_1998, Sanford_2018). These data indicate that the variant may be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submissions (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 23, 2023	This sequence change creates a premature translational stop signal (p.Pro422Leufs*58) in the AIRE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AIRE are known to be pathogenic (PMID: 11524731, 26141571). This variant is present in population databases (rs764878471, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with autosomal recessive autoimmune polyendocrinopathy syndrome (PMID: 9888391, 29437776). ClinVar contains an entry for this variant (Variation ID: 265456). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
