Questions about gene testing for diabetes

Gene testing for diabetes risks may not provide any benefit. Several companies now offer genetic testing for type-2 diabetes at a cost of hundreds of dollars. But two new studies suggest those tests may be no better for predicting diabetes risk than having a doctor ask some old-fashioned questions about weight, smoking status and family history.

The results suggest personalized medicine that is made possible by the expanded understanding of genetics is not yet as useful for the prediction of diabetes risk.
