VDJ-Insights: simplifying the annotation of genomic IG and TCR regions

Key Points

VDJ-Insights demonstrates over 99% concordance with curated annotations from multiple species, enhancing accuracy in immune region studies.
The tool identified 652 novel immunoglobulin alleles and 275 TCR alleles from 95 haplotypes, expanding our understanding of adaptive immunity.
Assessment using bioinformatic tools like VDJ-Insights improves gene segment functionality and annotates complex regions, enabling large-scale analysis.
This innovative software supports immunogenetic research but further studies are needed to evaluate its applicability across diverse populations.

Abstract

Accurate annotation of germline immunoglobulin (IG) and T cell receptor (TCR) loci is critical for understanding adaptive immunity. VDJ-Insights provides a user-friendly software package for characterizing these complex immune regions. In addition, it assesses gene segment functionality, identifies recombination signal sequences (RSS), and annotates complementary-determining regions 1 and 2 (CDR1, CDR2). VDJ-Insights achieved over 99% concordance with curated annotations from multiple species, outperforming existing annotation tools. When applied to 95 haplotypes from the Human Pangenome Reference Consortium, VDJ-Insights identified 652 and 275 novel IG and TCR alleles, respectively, highlighting its scalability for large immunogenetic studies.
