Common variants in genes primarily influencing insulin action (specifically INSR, PIK3R1, and SOS1) are significantly associated with Type 2 diabetes risk.

Genetic variants in your insulin signaling pathway (like INSR or PIK3R1) may make your cells less responsive to insulin. This is a common genetic risk factor. You can counteract this by focusing on interventions that improve insulin sensitivity, such as regular physical activity and maintaining a healthy weight.

GoodSupportsHIGH confidence
We examined 35 genes predicted to have their major influence on insulin action, and three (9%)—INSR, PIK3R1, and SOS1—showed significant associations with diabetes.
