Not So Precision Medicine: The Hidden Ancestral Biases in Genomic Care

Genomic precision medicine is marketed as comprehensive care tailored to a person’s DNA; however, this promise only holds true if the patient happens to be of European descent. Databases used to construct treatments rely on European-biased data. It means the further a person’s ancestry strays from Europe, the less accurate their treatment and risk assessment will be, leading to numerous complications. This brief addresses the need for rules mandating cross-ancestry validation, to ensure a more equitable medical future for patients regardless of background.
