bloodAGENT: a versatile tool for blood group typing and genomic variation analysis

Area of Science:

• Genomics
• Bioinformatics

Background:

• Accurate blood group allele determination is crucial for research and clinical settings.
• Next-generation and third-generation sequencing generate extensive genomic data, but analysis faces challenges with paralogous regions and haplotype integrity.
• Current blood group allele determination tools are often proprietary and lack flexibility.

Purpose of the Study:

• To develop a versatile, open-source tool for analyzing genomic variation and resolving blood group alleles.
• To address the limitations of existing proprietary tools in handling complex genomic data.

Main Methods:

• Development of bloodAGENT, an open-source bioinformatics tool.
• Utilizing genomic variation data for blood group allele analysis.
• Simulations to assess tool performance under varying data completeness scenarios.

Main Results:

• bloodAGENT demonstrates high concordance in blood group allele determination under typical conditions.
• Performance is strongly dependent on data completeness, with dropout rates being the primary factor affecting accuracy.
• Phasing breaks have a minor impact, but are significant in specific analytical situations.

Conclusions:

• bloodAGENT is a robust and flexible tool for blood group allele determination.
• The tool's performance highlights the importance of data completeness in genomic analyses.
• bloodAGENT offers a valuable open-source solution for complex genomic analyses in blood group research.
