Genome-wide gene-sleep interaction study identifies novel lipid loci in 732,564 participants.

Summary: Getting too little or too much sleep is linked to unhealthy cholesterol levels and heart disease. But why does this happen? Scientists looked at the DNA and sleep habits of over 700,000 people to find out. They discovered 17 new gene spots that connect sleep to blood fats. Some of these genes are linked to how our body uses Vitamin D. This huge discovery could lead to new medicines to help fix cholesterol problems in people who don't sleep well.
