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:2

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	May 21, 2021	For these reasons, this variant has been classified as Pathogenic. Disruption of the initiator codon has been observed in individual(s) with autosomal recessive autoimmune polyendocrinopathy syndrome (PMID: 19758376, 28446514, 28911151,16965330). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 551136). While this variant is present in population databases (rs121434258), the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. This sequence change affects the initiator methionine of the AIRE mRNA. The next in-frame methionine is located at codon 184. -
