Researchers at the Keck School of Medicine of USC are among the contributors to a large-scale, ethnically diverse genetic study that has expanded what scientists know about potential causes of type 2 diabetes.

The research, published in Nature Genetics, was conducted by the international MAGIC collaboration, made up of 400 global academics and led by researchers at the University of Exeter.

The study, a genome-wide meta-analysis, has identified more regions of the genome that are linked to blood glucose and insulin levels, features that contribute to the risk of type 2 diabetes. The findings demonstrate that, while 80-85% of genes linked to glucose and insulin levels are the same across different ethnic groups, a significant minority are present in only one or two ethnic groups.
