A global biobank analysis reveals nearly 70 percent of studied genomic data are derived from those of European descent

New York, NY (March 21, 2019) — In a perspective published today in the journal Cell, researchers from the Icahn School of Medicine at Mount Sinai reveal that genomic data extracted from population biobanks across the globe contain much less ethnic diversity than desirable. Of the nearly 5 million samples of DNA contributed to biobanks worldwide, 68 percent come from individuals of European ancestry. This lack of diversity not only limits researchers’ ability to identify associations between genetic variants and disease, but may also contribute to widening ethnic disparities in health care, ultimately preventing underrepresented minorities from benefiting from the fruits of personalized medicine.
