Test Code LAB3801 ImmuneSeq VEO-IBD/Early Onset Enteropathy DNA Sequencing

Clinical System Name

ImmuneSeq Very Early Onset Inflammatory Bowel Disease (VEO-IBD)/Early Onset Enteropathy DNA Sequencing

Description

Clinical Features

Very early onset inflammatory bowel disease (VEO-IBD) is defined by presentation before six years of age (Zheng et al., 2021). IBD represents a group of diseases including Crohn’s disease, ulcerative colitis, and IBD-unspecified that present with distinct clinical features (Ouahed et al., 2020). Individuals with VEO-IBD can exhibit variable symptoms such as bloody stools, frequent emesis, failure to thrive, intermittent fevers, arthralgias, and dermatologic manifestations (Ouahed et al., 2020). Monogenic variants of VEO-IBD can be classified as epithelial barrier defects, phagocytosis defects, T and B cell defects, T regulatory cells and signaling, and hyper- and auto-inflammatory conditions (Zheng et al., 2021). The therapeutic approaches for VEO-IBD can include various medications, surgical intervention, hematopoietic stem cell transplantation (HSCT), and nutritional approaches (Ouahed et al., 2020).

 

The Seattle Children’s Hospital Molecular Laboratory offers testing of 144 genes for the Very Early Onset Inflammatory Bowel Disease (VEO-IBD)/Early Onset Enteropathy panel. Reported genes are listed below.

 

Prevalence

VEO-IBD is estimated to represent approximately 6-15% of pediatric IBD cases (Krauthammer et al., 2023), and the incidence of childhood-onset IBD has been increasing in recent years (Ouahed et al., 2020).

 

Inheritance

VEO-IBD may occur de novo or may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner (Ouahed et al., 2020).

Methodology

Method: Next Generation Sequencing technology using an Illumina NextSeq instrument. Target region includes coding exons and a minimum of 10 bp of flanking intron boundaries of the genes tested. Target enrichment performed using a custom Integrated DNA Technologies (IDT) Exome Hyb Panel v2. 

 

Average coverage ~150x.

 

Limitations:

This testing is performed on an exome backbone with analysis restricted to the panel genes. This method can detect single nucleotide variants (SNVs), small deletions, small insertions, and copy number variants in the regions targeted. Some regions cannot be efficiently captured due to sequence homology or sequence properties. This method will not detect large insertions and deletions, complex indels, structural variants (e.g. inversions, translocations), short tandem repeats, or other complex variants. Variants located outside of targeted regions will not be detected.

 

Based on validation studies, the bioinformatics pipeline showed precision and detection >99% for SNVs in regions with coverage greater than 20x and high mapping quality. Sensitivity for CNVs involving multiple genes is >99% and sensitivity for intragenic CNVs is >90%. Mosaic sequence variants present at <25% allele frequency may not be reliably detected, and detection sensitivity is dependent on the nature of the variant. The sensitivity of detection of mosaic copy number variants has not been evaluated.

 

Reported Gene Lists

The Seattle Children's Hospital Molecular Laboratory offers different immune disorder panels based on clinical presentation with additional testing options. Reported gene lists are below and detailed descriptions are available. All panels include copy number analysis and may identify mosaicism.

**The UNC13D 253 kb inversion described in the literature (Meeths et al., 2011) is outside of the target region and will not be detected by this assay.

Reference Range

Interpretive report will be provided. Variants are classified using the ACMG/AMP guidelines (PMID: 25741868). Variants are that are considered neutral, risk alleles, or associated with carrier status for recessive disorders are not routinely reported.

Clinical Utility

While individually rare, immune disorders are a significant health burden. This is not a complete list, but genetic testing may be considered in individuals when the clinical differential diagnosis includes:

  • Dyskeratosis congenita
  • SCID
  • Bloom syndrome
  • CHARGE syndrome
  • Bone Marrow Failure
  • Roifman-Chitayat syndrome
  • SHORT syndrome
  • IMAGE-I syndrome
  • RIDDLE syndrome
  • Trichohepatoenteric syndrome
  • Wiskott-Aldrich syndrome
