The catalogue of insertions and deletions in the human genome could eventually help scientists to find treatments for diseases, tailored to the genetic makeup of individuals. We share some 97 to 99% of our DNA in common. The remaining 1 to 3% in the 'book of life', the human genome, reads differently in...
