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 12 ACMG points.

• PS1: Transcript NM_000383.4 (AIRE) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM1: In a domain HSR (size 104) in uniprot entity AIRE_HUMAN there are 27 pathogenic changes around while only 1 benign (96%) in NM_000383.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.991
• PP5: Variant 21-44286092-T-C is Pathogenic according to our data. Variant chr21-44286092-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 68230.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr21-44286092-T-C is described in Lovd as [Pathogenic].
