IMGT Allele-Align

IMGT Allele-Align compares two alleles to highlight nucleotide and amino acid differences for comparative analysis of immunoglobulins (IG), T cell receptors (TR), major histocompatibility complex (MHC) and related immune system proteins.

Key Features:

• Allele Comparison: Precise pairwise comparison of two alleles with identification of nucleotide and amino acid variations.
• Standardization: Uses IMGT-ONTOLOGY for standardized nomenclature, labels, and numbering systems to ensure consistent data representation.
• Integration with IMGT Suite: Interoperates with IMGT resources such as IMGT/LIGM-DB and IMGT/MHC-DB and leverages IMGT reference data for immunogenetics analyses.
• Interoperability: Supports Web services and XML Schema (IMGT-ML) for data exchange with other bioinformatics systems.

Scientific Applications:

• Medical Research: Analysis of immune repertoires and mutation patterns in contexts including autoimmune diseases, AIDS, leukemias, lymphomas, and myelomas.
• Veterinary Research: Comparative analysis of IG and TR repertoires across vertebrate species to study genome diversity and evolution.
• Biotechnology: Support for antibody engineering workflows including single chain Fragment variable (scFv) development, phage display, combinatorial libraries, and humanized antibody design.
• Clinical Applications: Use in diagnostic and monitoring applications such as detection of residual disease and support for immunotherapy and vaccinology studies.

Methodology:

Operates within a framework that bridges genes, sequences, and 3D structures using IMGT-ONTOLOGY axioms, enabling standardized analysis of genomic and expressed repertoires including next-generation sequencing (NGS) high-throughput data.
