An emerging melody composed of the notes from structural variants - Comment on ‘The fusion characteristics of RET fusion in pan-cancer among the Chinese population: A comprehensive genomic analysis’ by Chen et al

The identification of RET fusions has significantly advanced precision medicine in lung cancer; however, understanding of the structural features is limited. This commentary discusses a recent comprehensive study by Chen et al. analyzing RET fusions in a large Chinese pan-cancer cohort using DNA and RNA sequencing. We highlight its contribution to understanding fusion structure, diagnostic implications, and differences between Asian and Western populations, setting the stage for future research directions.
