GeneDx	RCV000378770	SCV000329055	pathogenic	not provided	2022-02-17	criteria provided, single submitter	clinical testing	Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss-of-function is a known mechanism of disease; Published functional studies demonstrate lack of expression of mRNA from AIRE-dependent genes (Oftedal et al., 2015); R257X variant is the most common Finnish pathogenic variant, present in 82% of Finnish APECED alleles, and is also common in the Northern Italian and Eastern European APECED patient populations (Finnish-German APECED Consortium 1997; Heino et al., 2001); This variant is associated with the following publications: (PMID: 22162465, 20718774, 24948345, 16965330, 11524733, 15886230, 11524731, 11298085, 22024611, 18616706, 9921903, 19807739, 12050215, 19863576, 25707324, 27065010, 27048654, 26891119, 14582926, 24158785, 18274776, 28458664, 30018023, 12951636, 11207636, 31588815, 30863741, 31956453, 33225392, 34078422, 34426522, 24493573, 32441320, 34235359, 26084028, 9398840)
Invitae	RCV000179294	SCV000832482	pathogenic	Polyglandular autoimmune syndrome, type 1	2024-01-31	criteria provided, single submitter	clinical testing	This sequence change creates a premature translational stop signal (p.Arg257*) in the AIRE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AIRE are known to be pathogenic (PMID: 11524731, 26141571). This variant is present in population databases (rs121434254, gnomAD 0.5%), including at least one homozygous and/or hemizygous individual. This premature translational stop signal has been observed in individual(s) with autoimmune polyendocrinopathy with candidiasis and ectodermal dysplasia (APECED) (PMID: 9398840, 20718774, 22024611). It is commonly reported in individuals of Finnish ancestry (PMID: 9398840). ClinVar contains an entry for this variant (Variation ID: 3307). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000179294	SCV001361217	pathogenic	Polyglandular autoimmune syndrome, type 1	2019-10-14	criteria provided, single submitter	clinical testing	Variant summary: AIRE c.769C>T (p.Arg257X), also known as the "Finnish major mutation", results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. Truncations downstream of this position have been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 0.00075 in 248166 control chromosomes in the gnomAD database, including 1 homozygote. c.769C>T has been reported in the literature in multiple individuals affected with Autoimmune Polyglandular Syndrome Type 1 (example, Aaltonen_1997, Giordano_2012, Cervato_2010). These data indicate that the variant is very likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in lack of transcriptional regulation by mutant AIRE of KRT14, an AIRE-dependant gene as observed by a lack of mRNA expression in-vitro (example, Oftedal_2015). Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

Johns Hopkins Genomics, Johns Hopkins University	RCV000179294	SCV001431521	pathogenic	Polyglandular autoimmune syndrome, type 1	2020-08-24	criteria provided, single submitter	clinical testing	This AIRE variant (rs121434254) is rare (<0.1%) in a large population dataset (gnomAD: 218/279538 total alleles; 0.08%; 1 homozygote) and has an entry in ClinVar. This variant has been reported previously in a homozygous or compound heterozygous state in multiple unrelated individuals affected with APS1. This nonsense variant results in a premature stop codon in exon 6 of 14 likely leading to nonsense mediated decay and lack of protein production. This variant alone is not expected to cause APS1. We consider c.769C>T to be pathogenic.
New York Genome Center	RCV000179294	SCV001480457	pathogenic	Polyglandular autoimmune syndrome, type 1	2020-06-05	criteria provided, single submitter	clinical testing	The c.769C>T, p.Arg257Ter nonsense variant identified in the AIRE gene has been reported previously in both the homozygous and compound heterozygous state in multiple unrelated individuals with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) [PMID: 9398840; PMID: 25707324; PMID: 30863741; PMID: 31588815]. This variant is the most common Finnish pathogenic variant, present in 82% of Finnish APECED alleles, and is also common in the Northern Italian and Eastern European APECED patient populations [PMID: 9398840]. Functional studies have demonstrated that cells transfected with the p.Arg257Ter allele lack expression of mRNA from AIRE-dependent genes [PMID: 26084028]. This variant has 0.06%frequency (84 heterozygous) in gnomAD database indicating this is a rare allele. The detected nonsense substitution truncates the protein at codon 257, which is 289 amino acids from the end of the protein and expected to result in an absent protein product through nonsense-mediated mRNA decay [PMID: 24681721.] Based on the available evidence, the c.769C>T, p.Arg257Ter variant in the AIRE gene is classified as pathogenic.

PreventionGenetics, part of Exact Sciences	RCV003421900	SCV004117021	pathogenic	AIRE-related condition	2023-06-15	criteria provided, single submitter	clinical testing	The AIRE c.769C>T variant is predicted to result in premature protein termination (p.Arg257*). This variant has been reported with a second AIRE variant in many unrelated individuals with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) (Nagamine et al. 1997. PubMed ID: 9398839; Finnish-German APECED Consortium. 1997. PubMed ID: 9398840; Björses et al. 2000. PubMed ID: 10677297; Stolarski et al. 2006. PubMed ID: 16965330; Podkrajsek et al. 2008. PubMed ID: 18682433; Orlova et al. 2010. PubMed ID: 20407228). In vitro experimental studies have demonstrated that this variant disrupts protein function (Björses et al. 2000. PubMed ID: 10677297; Halonen et al. 2004. PubMed ID: 14974083; Oftedal et al. 2015. PubMed ID: 26084028). This variant has also been observed in the heterozygous state without a second AIRE variant in some individuals with classic and atypical APECED with a proposed incomplete penetrance (Sedivá et al. 2002. PubMed ID: 12503856; Buzi et al. 2003. PubMed ID: 12843157; Orlova et al. 2010. PubMed ID: 20407228). However, there are many heterozygous individuals with no symptoms of APECED and an autosomal dominant mode of inheritance is not established. This variant is reported at a relatively high frequency (0.50% of alleles) in individuals of Finnish descent in gnomAD (http://gnomad.broadinstitute.org/variant/21-45709656-C-T) but has been shown to be a founder mutation in this population (Finnish-German APECED Consortium. 1997. PubMed ID: 9398840). This variant is also interpreted as pathogenic or likely pathogenic by many labs in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/3309). Nonsense variants in AIRE are expected to be pathogenic. This variant is interpreted as pathogenic for autosomal recessive AIRE-related disorders.
