We live in the age of big DNA data. Scientists are eagerly sequencing millions of human genomes in the hopes of gleaning information that will revolutionize health care as we know it, from targeted cancer therapies to personalized drugs that will work according to your own genetic makeup. There’s a big problem, however: the data we have is too white. The vast majority of participants in worldwide genomics research are of European descent. This disparity could potentially leave out minorities from benefitting from the windfall of precision medicine.
