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).

Significance:Likely pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is also known as X546C. 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. This variant results in an extension of the AIRE protein. Other variant(s) that result in a similarly extended protein product (p.*546Leuext*60) have been observed in individuals with AIRE-related disease (PMID: 28446514). This suggests that these extensions may be clinically significant. ClinVar contains an entry for this variant (Variation ID: 56222). This protein extension has been observed in individuals with APECED (PMID: 9717837, 18728167). This variant is present in population databases (rs386833673, gnomAD 0.009%). This sequence change disrupts the translational stop signal of the AIRE mRNA. It is expected to extend the length of the AIRE protein by 60 additional amino acid residues. -
