A project to map 100,000 DNA code sequences in the fight against cancer and rare inherited diseases will be lead by 11 NHS centres named by government on Monday.
More than 75,000 patients are expected to participate in the three-year scheme to collect and sequence the human genomes, including some with life-threatening and debilitating conditions.
Scientists and doctors hope the £300 million initiative launched in August will transform medicine by uncovering DNA data that can be used to develop and test new drugs and targeted diagnostic procedures.
Illumina will also invest about £162 million in the project over its lifetime.
The first group of "genomic medicine centres" will be linked to NHS trusts in 11 locations across England including London, Manchester, Birmingham and Cambridge, with recruitment of patients set to begin in early February.
More than 100 NHS trusts are expected to participate in the project over its three-year lifespan.
To start with the scheme will focus on five common cancers -- breast, bowel, ovarian, lung and CLL leukemia -- and 110 inherited conditions.
Suitable patients will be identified by their clinicians and put forward for genome sequencing after giving their informed consent.
Cancer patients will contribute two genomes, one from blood and another from a tumour sample. Genomes will also be sequenced from the close relatives of patients with inherited diseases.
Combining information from DNA samples with patients' health records will improve the prediction and prevention of cancers and rare inherited diseases, experts believe.
- 'Unlock secrets' -
Charity the Wellcome Trust and the Medical Research Council along with the NHS will contribute to the project, which will be overseen by Genomics England, a company set up by the Department of Health.
"Our NHS is better equipped for the emerging science that will determine the future practice of medicine than any other Western healthcare system," NHS England National Medical Director Bruce Keogh said.
"[It] puts us in a position to unlock a series of secrets about devastating diseases that have remained hidden for centuries for the whole of humankind."
Professor Mark Caulfield, chief scientist at Genomics England, said the new centres would play a central role in bringing together researchers, NHS clinicians and trainees "to work on whole genome data that has never been collected on this scale before."
Caulfield said drug companies would be restricted to using the facility like a reading library, using the data for research but prevented from taking it away.
Life Sciences Minister George Freeman described the establishment of the centres as "historic".
He said: "By launching the NHS Genomic Medicine Centres across the country, genomics goes from being something done in specialized laboratories to something that is beginning to be relevant to patients across the NHS, across the country."
