Scientists say they have discovered a gene linked to diabetes and obesity, offering hope for a diagnostic test. The Imperial College London team told Nature Genetics that spotting the problem early and intervening could save lives.

Experts have already predicted that the UK is facing an obesity and diabetes time bomb, with rates soaring among children and adults alike. The number of people in the UK with diabetes is predicted to reach three million by 2010.

Diabetes and obesity increase the likelihood of potentially fatal diseases such as heart attacks. While inactivity and poor diets are much to blame for obesity and the metabolic problems that can lead to full-blown diabetes, the authors of the latest study say some people are genetically prone as well.

Genetically prone In these individuals - up to 20% of Caucasians and 50% of black communities - leading a healthier lifestyle from the outset is imperative if they are to avoid problems in later life, say Dr Philippe Froguel and his team. However, Dr Froguel said those with a family history of diabetes and obesity should be particularly vigilant with regards to lifestyle. Dr Angela Wilson of Diabetes UK said: "This research is an important step in helping us unravel the genetics of Type 2 diabetes. We will be following its progress with interest."
