Researchers in Iceland believe they have identified a gene which accounts for 20 per cent of people with Type 2 diabetes.
The results have also been replicated in Denmark and the US.A gene called ‘chromosome 10’ was found to be 1.5 times more common in those with diabetes. People carrying one copy of the gene were found to be 45 per cent more likely to develop the condition and those with two copies were 141 per cent at greater risk.Dr Angela Wilson, Director of Research at Diabetes UK said: "Identifying a common gene in people with diabetes will certainly help with our understanding of the causes behind the condition, but it is only a small piece in a big jigsaw. "We know that Type 2 diabetes is caused by a mixture of genetic and environmental factors and that certain groups, including people from some minority ethnic groups and those who are overweight, are at an increased risk of developing the condition. "Just because someone does not carry the gene does not mean they will not develop the condition. All people, and particularly those in at risk groups, should eat a healthy diet and try to keep their weight down."
