We need treatments based on actual and not assumed genetic variation. That means assessing the patterns of diversity that reflect the distribution of human genetic variation across the globe. To this end, genetic ancestry should be understood as a continuum that it is not categorized in such a way that serves as a surrogate for race (40). Contemporary usage of continental ancestry categories (e.g., European, Middle Eastern, South Asian, Oceanic, East Asian, American, and African) serves as an example of how presumed “ancestral” geographies are assumed as equivalent to biological categories and serve as a false proxy for race. Such groupings correspond to Western racial categorizations and assume genetic homogeneity based on geographical separation, but these groupings misrepresent the actual distribution of genetic variants and neglect continuous movement of people and the resulting degree of mixture across global populations.

Precision medicine is an emerging field with immense potential for better understanding of diseases and improved treatment outcomes (1). Its focus: patterns of human genetic variation in populations and individuals—and how such patterns influence disease pathology and treatment. The field rejects the “one size fits all” approach to understanding disease, aspiring to develop tailored therapies that optimize treatment efficacy. It’s a promising but fledgling field that faces numerous challenges, both scientific and practical. But one challenge has not been fully appreciated: the lack of genetic diversity in research and clinical studies (2, 3)…
