The Olympic drug-testing centre in Essex, England, is to be turned into a £10 million science centre after the Games have finished.
Plans for converting the site of the Games laboratories east of London were announced on Wednesday.
The facility will allow better understanding of physical characteristics such as hair and eye colour, as well as diseases including dementia and diabetes.
The centre, run by GlaxoSmithKline, will be funded by £10 million over five years from the Medical Research Council and the National Institute for Health Research.
Advance speech notes from Prime Minister David Cameron said:
''This will take advantage of the extraordinary opportunities that lie in combining genetic data with the results of medical tests on tissues and blood.
''It will allow us to understand the characteristics of disease and how these link into genes and our environment.
''It's an impressive example of collaboration between top-class research, the NHS and industry.''
