CCAS

CCAS annotates cancer genomes by integrating multi-omics data to produce consensus annotations and multidimensional biological insights, including mutation signatures, gene set enrichment analysis, pathway annotation, and clinical-trial associations, across 10 cancer categories and 395 subtypes using information from 20 resources.

Key Features:

• Integration of Diverse Resources: Consolidates annotations from 20 recognized resources covering 10 cancer categories and 395 subtypes.
• Standardization and Curation: Curates and standardizes data using ontology frameworks to ensure consistency across sources.
• Multi-Omics Input Compatibility: Accepts single nucleotide variants/insertions or deletions, expression profiles, copy number variations, and methylation levels as input.
• Consensus Annotation Output: Generates consensus annotations that synthesize evidence across integrated resources.
• Multidimensional Annotation Information: Provides mutation signature patterns, gene set enrichment analysis, pathway annotation, and clinical trial–related information for functional interpretation.

Scientific Applications:

• Individual-level cancer genome interpretation: Delivers comprehensive annotations across multiple omic layers for single-patient analyses.
• Biomarker and therapeutic target discovery: Enables identification of candidate biomarkers and potential therapeutic targets via integrated annotation and enrichment/pathway analyses.
• Mechanistic and mutational-process characterization: Supports analysis of mutation signature patterns and pathway involvement to elucidate tumor biology.
• Clinical-trial annotation support: Associates genomic findings with clinical trial–related information to inform translational research.

Methodology:

Data from 20 resources are integrated and standardized using ontology frameworks; the system accepts SNV/indel, expression, copy number variation, and methylation inputs, produces consensus annotations, and provides mutation signature analysis, gene set enrichment analysis, pathway annotation, and clinical trial–related information.
