Professor Sir John Burn is Professor of Clinical Genetics at Newcastle University and a non-executive director of NHS England where at the time of submission he was deputy chair of Specialised Commissioning at NHS England. He helped write the 2003 government White Paper on Genetics which used warfarin genotyping as an example of future deployment of Pharmacogenetics. He has been working for 10 years with a small biotechnology company called QuantuMDx Ltd, based in Newcastle, to develop point of care DNA diagnostic devices. He is now employed part time as medical director and Chair and hold shares in the company. He chose warfarin genotyping as a suitable target for development of a disposable diagnostic cassette for use in clinic. This is expected to enter trials in the next 12 months.
