Phenotyping Genetic Risk for Type 2 Diabetes

Summary

This study tests the hypothesis that non-diabetic individuals with a high genetic risk score for type 2 diabetes have impaired glucose tolerance and insulin resistance compared to those with a low genetic risk score for type 2 diabetes.

Exclusion Criteria:

* prior diagnosis of type 1, type 2, or secondary diabetes
* use of medications that would impact glucose and insulin response such as steroids, metformin or other anti-diabetic medication
