Narrator: This is Science Today. An international team of scientists led by the University of California , Davis has found distinct genetic profiles for Northern and Southern Europeans. Michael Seldin, chair of the Rowe Program in Genetics at the UC Davis Medical School, says these findings provide a method for scientists to take into account European ancestry when looking for genes that are involved in diseases.
Seldin: This information will be applied in very large studies that are currently underway looking for diseased genes in rheumatoid arthritis, in Crohn's disease and systemic lupus and diabetes and the list goes on.
Narrator: Little has been known about the distribution of genetic variation in European populations and how much that distribution matters in terms of doing genetic studies.
Seldin: This is really the first study to look in detail at this European population structure.
