Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 1P and 16B. PP3 BP6_Very_Strong BS1 BS2

The NM_000383.4(AIRE):c.1404G>A(p.Thr468=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00179 in 1,569,294 control chromosomes in the GnomAD database, including 24 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. T468T) has been classified as Likely benign.

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 Benign. Variant got -15 ACMG points.

• PP3: Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
• BP6: Variant 21-44294404-G-A is Benign according to our data. Variant chr21-44294404-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 35661.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr21-44294404-G-A is described in Lovd as [Benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00566 (857/151398) while in subpopulation AFR AF= 0.0165 (679/41190). AF 95% confidence interval is 0.0155. There are 11 homozygotes in gnomad4. There are 405 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 11 AD,AR gene
