HiFIseek: Gene-specific enrichment of high-impact mutations in associated genomic regions.

HiFIseek reveals that gene-CRR associations and FI scoring methods show little consensus, significantly affecting the detection of high-impact regulatory variants in cancer genes.

• Why it matters: Understanding non-coding variants that disrupt gene regulation is crucial for identifying cancer drivers and risk factors, yet current methods lack systematic evaluation of their consistency and impact.
• What they did: The study developed HiFIseek, a Snakemake pipeline that applies two enrichment detection methods across multiple gene-CRR and FI score combinations, analyzing eight cancer cohorts and breast cancer SNPs.
• The result: HiFIseek identified cancer-related genes with high-impact variants, including known cancer genes like BRCA1, demonstrating its utility despite variability across scoring methods, and advancing approaches to interpret non-coding mutations.
