Although genetic screening does seem to help identify people at risk for type 2 diabetes, current methods are just as effective.
In a couple of new studies, researchers looked at newly discovered “genetic variants” for an associated increased risk for type 2 diabetes. Results for both studies showed that the risk for type 2 diabetes increased with the more genetic variants found in the volunteers.
However, the screening did little to outweigh the benefit of traditional screening methods, which include family history, obesity and impaired glucose tolerance, according to diabetes researcher James B. Meigs, MD, MPH, of Massachusetts General Hospital.
“The genomic revolution is here, and it is possible to predict risk for diseases like diabetes by assessing genetic risk factors,” says Meigs. “But this field is in its infancy. The message here is, ‘stay tuned.'”
