ESC

ESC catalogs SARS-CoV-2 genetic variants associated with immune escape to support analysis of antibody neutralization, vaccine breakthrough, and spike protein functional impacts.

Key Features:

• Comprehensive variant collection: Contains 5,258 variant entries including 2,068 unique variants with documented associations to immune escape.
• Annotated neutralization evidence: Records experimental associations with neutralizing agents including monoclonal antibodies, oligoclonal antibody panels, convalescent plasma, and vaccine breakthrough infections.
• Spike protein focus: Emphasizes mutations within spike protein domains relevant to antibody binding and potential evasion of neutralization.
• Manual literature curation: Entries are derived from curated data extracted from published literature and preprints with linked evidence for immune escape.

Scientific Applications:

• Epidemiology and evolution: Enables interpretation of variant emergence and evolutionary trajectories in the context of immune selection pressure.
• Immune escape characterization: Supports analysis of how specific spike mutations affect antibody neutralization and immune evasion mechanisms.
• Vaccine and therapeutic evaluation: Informs assessment of vaccine breakthrough events and monoclonal/oligoclonal antibody susceptibility to viral variants.
• Research on disease pathogenesis and transmission: Provides variant-level data to investigate links between mutations, pathogenicity, and transmissibility.

Methodology:

Variants and associated evidence were manually curated from published literature and preprints, collating documented links between specific spike mutations and reduced neutralization by monoclonal antibodies, oligoclonal panels, convalescent plasma, or vaccine breakthrough cases.
