    Area of Science:

    • Genomics
    • Cancer Research
    • Bioinformatics

    Background:

    • Cancers exhibit somatic mutations, categorized as small (1-50 base pairs) or large (>50 base pairs).
    • Large mutational events include copy-number and structural variants, crucial for understanding cancer biology and clinical outcomes.
    • Existing tools primarily focus on small somatic mutations, leaving a gap in analyzing large-scale genomic alterations.

    Approach:

    • Introduced a new version of SigProfilerMatrixGenerator with integrated analysis for large mutational events.
    • Supports analysis of copy-number variants and structural variants using established classification schemas.
    • Accommodates data from diverse algorithms and modalities, with Python implementation and an R wrapper.

    Key Points:

    • Provides the first standardized bioinformatics tool for exploring large-scale mutational events.
    • Enables visualization and exploration of copy-number and structural variants.
    • Facilitates deeper biological and clinical insights from cancer genome analysis.

    Conclusions:

    • SigProfilerMatrixGenerator offers a standardized solution for analyzing large mutational events in cancer.
    • The tool supports two classification schemas for copy-number and structural variants.
    • Freely available with comprehensive documentation for user accessibility.
