The DNA samples will be used for research purposes only. Qualified researchers will need permission from a special committee with expertise in genetics and overseeing and safeguarding access to the samples. They’ll only be given permission if their research will benefit the public. Researchers from commercial organisations will usually partner with public organisations (e.g. the NHS or universities) except under circumstances of exceptional potential public benefit.
The analysis of DNA is subject to funding, which means any data may not be available for some time.
