Genetic Variant AIRE:p.Arg139Gly (chr21-44287085-CGA-GGC) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is The variant received 2 classification points (ACMG Germline Pathogenicity v2019). PM2

The NM_000383.4(AIRE):c.415_417delCGAinsGGC (p.Arg139Gly) variant causes a missense change. Note: allele frequency estimates from gnomAD may be inaccurate for this variant type (MNP or indel longer than 3 bp) due to technology limitations. The variant is absent from the gnomAD population database at sites with sufficient sequencing coverage. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.R139G: Likely_benign (ClinVar VariationId 2066266, 1 star); p.R139P: Uncertain_significance (ClinVar VariationId 1449867, 1 star)

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).
