Pricing Comments
Testing run on PG-select capture probes includes CNV analysis for the gene(s) on the panel but does not permit the optional add on of exome-wide CNV analysis. Any of the NGS platforms allow reflex to other clinically relevant genes, up to whole exome or whole genome sequencing depending upon the base platform selected for the initial test.
An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.
This test is also offered via a custom panel (click here) on our exome or genome backbone which permits the optional add on of exome-wide CNV or genome-wide SV analysis.
Turnaround Time
3 weeks on average for standard orders or 2 weeks on average for STAT orders.
Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics
Clinical Features
Autoimmune polyendocrinopathy syndrome type 1 (OMIM# 240300) is an autoimmune disease characterized by Addison disease (a malfunction of adrenal glands), hypoparathyroidism (a malfunction of parathyroid glands), chronic mucocutaneous candidiasis (a fungal infection that affects the skin and mucous membranes) (Nagamine et al. 1997; Finnish-German APECED Consortium 1997). Some patients may only have two of these three features while others have all of them. This multi-system disease can also affect skin, nails, gonads, eyes, the thyroid, and the digestive system. In most cases, the age of disease onset is during childhood or adolescence. The disease is also commonly termed autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED). Although it occurs worldwide, a much higher prevalence has been found in three populations: Finns (~1/25,000), Iranian Jews (~1/9,000) and Sardinians (1/14,500) (Björses et al. 2000).
Genetics
Autoimmune polyendocrinopathy syndrome type 1 is an autosomal recessive disorder caused by defects in the AIRE gene (Nagamine et al. 1997; Finnish-German APECED Consortium 1997). AIRE has 14 coding exons that encode an autoimmune regulator. Genetic defects of AIRE include missense, nonsense, splicing site mutations, small deletion/insertions (Human Gene Mutation Database). Large deletions involving AIRE have also been reported, but are relatively uncommon. Although AIRE defects are spread throughout the whole coding region, mutational hotspots have been observed in exons 2, 6, 8 and 10 (Björses et al. 2000). R257X and R139X account for 85% of the Finnish APECED chromosomes and 92% of the Sardinian disease alleles, respectively. The 13bp deletion (c.967_979del13) in exon 8 is also common among patients from different populations (Pearce et al. 1998; Wolff et al. 2007; Heino et al. 1999).
Clinical Sensitivity - Sequencing with CNV PG-Select
In a cohort of 112 APECED patients of diverse ethnic backgrounds worldwide (including 63 Finns), 91% of pathogenic AIRE alleles were found via DNA sequencing (Björses et al. 2000).
Testing Strategy
This test provides full coverage of all coding exons of the AIRE gene, plus ~10 bases of flanking noncoding DNA. We define full coverage as >20X NGS reads or Sanger sequencing.
Indications for Test
Candidates for this test are patients with autoimmune polyendocrinopathy syndrome type 1. Testing is also indicated for family members of patients who have known AIRE mutations. This test may also be considered for the reproductive partners of individuals who carry pathogenic variants in AIRE.
