High flyers at risk

If someone carries the allele for Huntington’s disease it is currently certain that sooner or later they will develop the symptoms of the disease and eventually die. However, if genetic testing becomes routine, and the secrets of our DNA are revealed, then many less clear situations will show up – and the ethical dilemmas will multiply.

Much of the information in our genome will simply show an increased tendency towards certain conditions such as diabetes, Parkinson’s disease, heart disease, cancer and Alzheimer’s. Whether we go on to develop the symptoms of these diseases will depend both on the rest of our genetic makeup and the way we live our lives.

chartConsider pilots who fly commercial airliners. Obviously if a pilot has a heart attack whilst flying a jumbo jet carrying hundreds of people it is a serious situation for all concerned. It may well be possible in the fairly near future to carry out a genetic test to see if someone has an increased risk of developing heart disease in middle age.


 
Activity
  1. If such a test becomes available, should all airline pilots be forced to take it?
  2. If all pilots are tested, how would you suggest the information is used?
  3. If your DNA profile shows you have a raised likelihood of suffering heart disease in your 40s, should you be allowed to train and work as an airline pilot?
  4. Do you think it is acceptable for genetic information about an individual to be used in this way?

Discuss your answers with other people. Try and quantify the number of different opinions put forward and the number of people holding different views – can opposing views be reconciled?
