October 25, 2016 | Genome-wide association studies scan the DNA of many people to spot genetic variants associated with drivers of disease. But large population groups—including Africans, Latin Americans, and native or indigenous people—are hugely underrepresented in these studies and genomics research in general. Without this information, researchers may be missing key genetic factors that play a role in disease susceptibility and drug response among different population groups. Bio-IT World discussed this topic earlier this month.
