1576-Mapping Significantly Mutated Protein Regions in Cancer

Researchers have developed a proteo-genomics framework that integrates protein structural data with genomic sequences from over 130,000 cancer patients. This model identifies significantly mutated regions across 173 cancer-related genes, mapping where mutations cluster within three-dimensional protein structures. These high-density regions frequently align with critical functional domains, such as DNA-binding sites or catalytic centers, revealing how specific mutations drive tumor growth. The study distinguishes between oncogenes and tumor suppressors based on whether mutations disrupt protein stability or alter molecular interactions. Furthermore, this atlas helps clinicians interpret rare or conflicting genetic variants by providing a standardized map of a mutation's likely biological impact. By shifting focus from the whole gene to specific regions, the framework improves the precision of genomic medicine and patient outcome predictions.
