Failing to account for genetic variation according to ancestry will impact the ability to accurately diagnose diabetes, researchers have said. Ethnic diversity in one large-scale study meant more regions of the genome linked to type 2 diabetes-related traits were identified than if the research had been conducted in Europeans alone, scientists suggested. Experts said the findings demonstrated that expanding research into different ancestries yielded more and better results, as well as ultimately benefiting global patient care. It is estimated that until now, nearly 87% of genomic research of this type has been conducted in Europeans. This has meant that the way these findings are implemented may not be best applied to people with non-European ancestries, researchers said.
