More findings on genetic complexity behind type 2 diabetes

Using a new method, diabetes researchers at Lund University, Sweden, have been able to reveal more of the genetic complexity behind type 2 diabetes. The new research findings have been achieved as a result of access to human insulin-producing cells from deceased donors and by not only studying one gene variant, but many genes and how they influence the level of the gene in pancreatic islets and their effect on insulin secretion and glucose control of the donor.

"With this approach, we can explain 25 per cent of variations in blood sugar levels. Previously, the best studies have explained less than three per cent", says Leif Groop from Lund University Diabetes Centre, the principal author of the study, which has been published in the journal Cell Metabolism.

The findings of the study provide greater insight into why, in cases of type 2 diabetes, the insulin-producing beta cells cease to be able to perform their function of producing sufficient insulin to keep blood sugar levels under control.

"We have linked different gene variants to their effect on donated human beta cells and have compared cells from non-diabetics and diabetics", says Professor Groop.

The research team had access to cells from 63 donors, nine of whom had had type 2 diabetes.

The starting point for the work was the 47 known gene variants that have a statistical link to diabetes.
