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).

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.11172161 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.5, offset of 17, new splice context is: caactccccccggggcttAGgtc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change affects an acceptor splice site in intron 9 of the AIRE gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in AIRE are known to be pathogenic (PMID: 11524731, 26141571). This variant is present in population databases (rs780906602, gnomAD 0.0009%). For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 551625). This variant is also known as IVS9-1G>A. Disruption of this splice site has been observed in individual(s) with autosomal recessive autoimmune polyendocrinopathy syndrome (PMID: 9888391, 26114819). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. -

Collection Method:clinical testing

Variant summary: AIRE c.1096-1G>A is located in a canonical splice-site and is predicted to affect mRNA splicing resulting in a significantly altered protein due to either exon skipping, shortening, or inclusion of intronic material. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing and loss of AIRE function. Several computational tools predict a significant impact on normal splicing: Four predict the variant abolishes a canonical 3' acceptor site. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 4e-06 in 247696 control chromosomes. c.1096-1G>A has been reported in the literature in individuals affected with Autoimmune Polyglandular Syndrome Type 1 (example: Meisel_2021). These data indicate that the variant is likely to be associated with disease. The following publication has been ascertained in the context of this evaluation (PMID: 34061776). ClinVar contains an entry for this variant (Variation ID: 551625). Based on the evidence outlined above, the variant was classified as pathogenic. -
