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).

Collection Method:clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 76 of the AIRE protein (p.Asp76Asn). This variant is present in population databases (rs146810389, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with AIRE-related conditions. ClinVar contains an entry for this variant (Variation ID: 458617). 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.226G>A (p.Asp76Asn) results in a conservative amino acid change located in the HSR domain of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.9e-05 in 276948 control chromosomes. This frequency is not significantly higher than expected for a pathogenic variant in AIRE causing Autoimmune Polyglandular Syndrome Type 1 (7.9e-05 vs 0.0028), allowing no conclusion about variant significance. To our knowledge, no occurrence of c.226G>A in individuals affected with Autoimmune Polyglandular Syndrome Type 1 and no experimental evidence demonstrating its impact on protein function have been reported. A ClinVar submission from another clinical diagnostic laboratory (evaluation after 2014) cites the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.226G>A (p.D76N) alteration is located in exon 2 (coding exon 2) of the AIRE gene. This alteration results from a G to A substitution at nucleotide position 226, causing the aspartic acid (D) at amino acid position 76 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
