Nobel winner eyes genetics

WA's Nobel Laureate scientist Barry Marshall has found out, thanks to gene mapping, he has twice the risk of developing Alzheimer's Disease and a 20 per cent chance of going bald - but he is not fussed.

While Professor Marshall made his name investigating bacteria that causes stomach ulcers, he is now a passionate advocate for the science of genomics, likening its impact on the world to the industrial revolution.

During a speech at the National Press Club in Canberra yesterday, Professor Marshall predicted that everyone would soon be able to find out their own genetic blueprint for as little $200.

This could lead to earlier detection of health risks and diseases, save money on medical bills, eradicate some diseases - and even revolutionise matchmaking.

Professor Marshall, who is having his genome sequenced by a Perth lab, said one of the community's biggest concerns about genetics, that insurance companies would use the information to deny people cover, was unfounded.
