Submitting Novel Full-Length HLA, MIC, and KIR Alleles with TypeLoader2

Area of Science:

• Immunogenetics
• Bioinformatics
• Genomic Databases

Background:

• The Immuno Polymorphism Database (IPD) is crucial for immunogenetics, but current genotyping often relies on limited gene regions.
• Advancements in next-generation sequencing (NGS) enable full-gene genotyping, necessitating updated, comprehensive reference sequences in databases.
• Manual annotation and submission of novel full-length allele sequences to IPD are laborious and prone to errors, hindering data contribution.

Purpose of the Study:

• To present TypeLoader2, a software tool designed to streamline the preparation and submission of novel HLA, MIC, and KIR allele sequences.
• To facilitate the update of immunogenetics databases with complete genetic reference sequences for current and future applications.
• To reduce the time and potential for errors associated with manual submission processes.

Main Methods:

• Development and application of TypeLoader2 software for processing novel allele sequences.
• Automation of sequence annotation, file generation, and parts of the submission workflow to ENA and IPD.
• Utilizing TypeLoader2 for preparing and submitting Human Leukocyte Antigen (HLA), MIC, and Killer-cell Immunoglobulin-like Receptor (KIR) alleles.

Main Results:

• TypeLoader2 successfully automates key steps in preparing and submitting novel allele sequences.
• The software simplifies the process, making it more efficient and less error-prone for researchers and laboratories.
• Facilitates the enrichment of immunogenetics databases with complete, high-quality genetic data.

Conclusions:

• TypeLoader2 is a valuable tool for the immunogenetics community, enhancing data submission efficiency.
• The software supports the crucial task of updating IPD with full-length allele sequences, vital for advancing immunogenetic research.
• Freely available software encourages broader participation in database enrichment.
