SOAPTyping

SOAPTyping performs high-resolution HLA genotyping from Sanger sequencing data to identify HLA class I and II alleles for biomedical and clinical applications.

Key Features:

• High-resolution HLA genotyping: Uses Sanger sequencing traces to generate precise HLA allele predictions.
• HLA class I and II support: Targets both HLA class I and class II loci for comprehensive typing.
• IMGT/HLA database comparison: Compares sequence data against the IMGT/HLA reference database for allele assignment.
• Group-specific sequencing primers (GSSP) module: Implements GSSP-based analysis to resolve ambiguous typing results.
• Validation and performance: Reported concordant results with established methods on 36 UCLA International HLA DNA Exchange samples and 100 clinical samples and a reported processing speed up to five times faster than uTYPE.

Scientific Applications:

• Immune response profiling: Provides allele-level HLA data useful for studies of immune response and immunogenetics.
• Clinical HLA typing: Applicable to clinical diagnostics requiring high-resolution HLA allele identification.
• Method validation and benchmarking: Enables validation and comparison of HLA typing approaches using reference and clinical sample sets.

Methodology:

Compares Sanger sequencing data to the IMGT/HLA database and employs a GSSP module to address ambiguous typings.
