Narrator: This is Science Today. A new study is providing a method for scientists to take into account European ancestry when looking for genes involved in disease. Michael Seldin, chair of the Rowe Program in Genetics at the University of California , Davis Health System, led the study.
Seldin: What we found was that the largest difference was between Northern and Southern European countries in our initial analyses. Now these differences in Europe are quite small compared to the differences between different continents. But even so, these differences can lead to false results in doing various studies to find disease-linked genes.
Narrator: Knowing that Europeans fall into two genetic groups may improve genetic studies of human disease such as rheumatoid arthritis, systemic lupus, hypertension and Diabetes Type 1 and 2. For Science Today, I'm Larissa Branin .
