Genetic roulette in a new world

Dr Robin Hesketh, Senior Lecturer in Cambridge University's Department of Biochemistry and author of Betrayed by Nature, explains how advances in inexpensive, rapid gene sequencing and expression analysis is revolutionising cancer research and the development of new treatments.

In 2003 it was a sensation. No really – it’s probably true that in medicine only the first human heart transplant operation back in 1967 has generated as much publicity. That was in the pre-web dark age but, nevertheless, the South African surgeon Christiaan Barnard was immortalized as a global hero: even the patient’s name was on everyone’s lips (Louis Washkansky if you’re struggling to recall) and you can re-live the whole event at the Groote Schuur Hospital museum in Capetown. But, although 2003 was just a decade ago, in today’s world sensations fade almost with the following dawn, whether they are pop groups or life-changing scientific advances.
 
So if now you mention “The Human Genome Project” to a man on the Clapham omnibus you are likely to elicit only a puzzled look. What happened in 2003 was of course that the genetic code – that is the sequence of bases in DNA – was revealed for the entire human genome. And an astonishing triumph it was, not least because, in contrast to almost everything else in history with a major British component, it was completed within schedule and under cost.
