Could we screen genes for disease risk nation-wide?

For many years it's been expensive and challenging to do genetic testing that works out if you're at greater risk of something like a heart attack or a specific type of cancer.That's meant testing is limited to those who already have a condition or a strong family history.But the decreasing costs and increasing accessibility of these tests means expanding their use is becoming a stronger possibility.A new pilot study for population-wide genomic screening found one in 50 people were at high risk of developing certain conditions based on their genes.And in the sample of 10,000 people, more than half of them had no family history of the diseases they were at risk of.GuestDr Jane Tiller, Ethical Legal and Social Advisor, Public Health Genomics, Monash UniversityReferencesFeasibility and outcomes of the DNA Screen nationwide adult genomic screening pilot
