- The £100 million will go on training genetic scientists, mapping patients' DNA, and creating systems for handling the information.
- The project that first sequenced a human genome in 2000 cost around £500m, but technical advances mean the bill has dropped dramatically to under £1,000 per person.
- Officials believe allocating NHS funds to mapping 100,000 people's codes will drive down costs even further by "priming the pump".
- Patients will be asked for permission before their DNA is sequenced, and data will be anonymised before it is stored.
- The Government also announced that £100 million of new science funding allocated in the Autumn Statement would go to life sciences.
- The money will help build research capabilities for synthetic biology, facilities for manufacturing cell and biologic medicines such as antibodies and vaccines.
