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:2Uncertain:1

Likely pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Oct 26, 2023	This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 8 of the AIRE protein (p.Arg8Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individuals with autosomal recessive autoimmune polyendocrinopathy syndrome (PMID: 17118990, 27253668). ClinVar contains an entry for this variant (Variation ID: 552873). 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) performed at Invitae indicates that this missense variant is expected to disrupt AIRE protein function with a positive predictive value of 95%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

PreventionGenetics, part of Exact Sciences

May 22, 2024

The AIRE c.22C>T variant is predicted to result in the amino acid substitution p.Arg8Cys. This variant has been reported in multiple individuals with autosomal recessive autoimmune polyendocrine syndrome (Table 3, Wolff et al. 2007. PubMed ID: 17118990; Bruserud et al. 2016. PubMed ID: 27253668). This variant is reported in 0.0020% of alleles in individuals of European (non-Finnish) descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
