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).

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Aug 29, 2018	Variant summary: AIRE c.1566+8C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 5/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0022 in 276242 control chromosomes (3 homozygotes), predominantly within the Non-Finnish European subpopulation in the gnomAD database at a frequency of 0.0032, including 1 homozygote. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is higher than the estimated maximal expected allele frequency for a pathogenic variant in AIRE causing Autoimmune Polyglandular Syndrome Type 1 phenotype (0.0028), suggesting the variant is a benign polymorphism found primarily in populations of Non-Finnish European origin. To our knowledge, no occurrence of c.1566+8C>T in individuals affected with Autoimmune Polyglandular Syndrome Type 1 and no experimental evidence demonstrating its impact on protein function have been reported. Three ClinVar submissions from other clinical diagnostic laboratories (evaluation after 2014) cite the variant as likely benign, benign, or uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -
