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

Verdict is Pathogenic. Variant got 16 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 21-44289792-GC-G is Pathogenic according to our data. Variant chr21-44289792-GC-G is described in ClinVar as [Pathogenic]. Clinvar id is 3315.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr21-44289792-GC-G is described in Lovd as [Pathogenic].

Submissions by phenotype

Polyglandular autoimmune syndrome, type 1 Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 09, 2023	This sequence change creates a premature translational stop signal (p.Ala264Leufs*114) in the AIRE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AIRE are known to be pathogenic (PMID: 11524731, 26141571). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with autoimmune polyendocrinopathy syndrome (PMID: 14557425). ClinVar contains an entry for this variant (Variation ID: 3315). For these reasons, this variant has been classified as Pathogenic. -
