Population cohort study finds six genetic variants associated with 'bad' cholesterol
A new study presages a real aim of genetics: to look at whole populations to in order determine the significance of individual genetic variants for individual health. The research team, whose work is published in Nature Genetics, find six novel genetic variants that are associated with lipid levels, a common indicator of heart or artery disease.
The power of 'genetic microscopes' has increased because the methods are in place to study many thousands of DNA samples. This study, involving over 20,000 samples and researchers from a dozen European countries, is the first to find such lipid-gene links by looking at the general population, rather than patients. The study is has been funded by an EU project, ENGAGE (www.euengage.org).
A search for a lipid-gene link through such large numbers of unselected people has not been published before. The findings increase hopes for improved predictive diagnosis, which could lead to improved public health measures and early prescription of effective treatments.
