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).

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 484 of the AIRE protein (p.Val484Met). This variant is present in population databases (rs367966318, gnomAD 0.02%). This missense change has been observed in individual(s) with AIRE-related conditions (PMID: 12843157, 26084028, 34573280). ClinVar contains an entry for this variant (Variation ID: 550499). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on AIRE protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: AIRE c.1450G>A (p.Val484Met) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00011 in 215656 control chromosomes (gnomAD). This frequency is not significantly higher than expected for a pathogenic variant in AIRE causing Autoimmune Polyglandular Syndrome Type 1 (0.00011 vs 0.0028), allowing no conclusion about variant significance. c.1450G>A has been reported in the literature in individuals affected with Autoimmune Disorders/Immunodeficiencies (Buzi_2003, Grossi_2021). These reports do not provide unequivocal conclusions about association of the variant with Autoimmune Polyglandular Syndrome Type 1. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Three ClinVar submitters have assessed the variant since 2014: all classified the variant as of uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -
