Distribution of Genomic Alterations by Tier Classification: Interactive Sunburst Plot

This dataset accompanies a study of a gastric cancer cohort profiling next-generation sequencing (NGS) results under the AMP/ASCO/CAP tier classification (tiers A–D) to characterize the landscape of clinically actionable alterations and their potential implications for matched therapy (e.g., identifying candidates for targeted agents or trial enrollment). he interactive sunburst plot summarizes the GC cohort’s genomic alterations across AMP/ASCO/CAP tiers A–D, organized by hierarchical rings (inner → outer: tier → alteration type → gene).
