a population group that has a genetic susceptibility to type 2 diabetes is
Genetic causes of diabetes mellitus type 2 However, environmental factors (almost certainly diet and weight) play a large part in the development of type 2 diabetes in addition to any genetic component. Genetic risk for type 2 diabetes changes as humans first began migrating around the world, implying a strong environmental component has affected the genetic-basis of type 2 diabetes.[20][21] This can be seen from the adoption of the type 2 diabetes epidemiological pattern in those who have moved to a different environment as compared to the same genetic pool who have not. Immigrants to Western developed countries, for instance, may be more prone to diabetes as compared to its lower incidence in their countries of origins.[22] Such developments can also be found in environments which have had a recent increase in social wealth, increasingly common throughout Asia.
