Narrator: This is Science Today. A multinational study validated by the University of California, San Francisco has found that a key genetic mutation is responsible for type 2 diabetes in 10 percent of Caucasians with the disease.
Golfine: That's a lot of people. It's two and a half million people in the United States and more in Europe and probably more around the world.
Narrator: According to study leader Ira Goldfine, the sedentary lifestyle and poor dietary habits associated with industrialization can accelerate the onset of diabetes in those who are genetically predisposed to the disease. The next step, he says, is to expand the study to other ethnic groups and developing countries.
Goldfine: It's the same in all industrialized countries and it's increasing in countries that are industrializing such as India and China. For instance, India has about a billion population and they have about 75 million type 2 diabetics. So more studies need to be done on this gene and other ethnic groups.
