Common variants in genes influencing pancreatic beta-cell function make a significant contribution to the inherited component of Type 2 diabetes, often with small individual effects.

Type 2 diabetes is not caused by a single 'diabetes gene' but by a combination of many common genetic variants, each with a small effect. This genetic complexity means that your risk is the sum of many small genetic contributions. Understanding this can help explain why some people with similar lifestyles have different diabetes risks.

GoodQualifiesHIGH confidence
These results confirm the genetic complexity of Type 2 diabetes and provide evidence that common variants in genes influencing pancreatic b-cell function may make a significant contribution to the inherited component of this disease.
