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).

Uncertain significance, no assertion criteria providedclinical testingNatera, Inc.Nov 11, 2019- -
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 16, 2022This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 265 of the AIRE protein (p.Ala265Val). This variant is present in population databases (rs775896896, gnomAD 0.003%). 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: 583233). 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 not expected to disrupt 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. -
