Genetic Ancestry Correlations with Driver Mutations Suggest Complex Interactions between Somatic and Germline Variation in Cancer.

Carrot-Zhang and colleagues describe associations between Native American ancestry and the somatic mutational landscape in lung cancer, including tumor mutation burden and specific driver mutations in EGFR, KRAS, and STK11. Local ancestry analysis suggests that specific germline loci, and not environment, underlie these associations.See related article by Carrot-Zhang et al., p. 591.
