Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM1 PM2 PM5 PP3_Strong PP5

The NM_000383.4(AIRE):​c.239T>G​(p.Val80Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V80L) has been classified as Likely pathogenic.

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 11 ACMG points.

• 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
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.979
• PP5: Variant 21-44286663-T-G is Pathogenic according to our data. Variant chr21-44286663-T-G is described in ClinVar as [Pathogenic]. Clinvar id is 3317.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr21-44286663-T-G is described in Lovd as [Pathogenic].
