Genetics and Heart Disease

by Kevin on February 18, 2009

Scientists have known for some time that the risk of developing early onset heart disease (under the age of 40) had a hereditary link, but did not which genetic marker was responsible for it. New research into the gene believed responsible for heart disease has now revealed that a variation of the protein neuropeptide Y (NPY) is the likely culprit. It’s probably no coincidence that this protein has been linked to the ability to control appetite.

When researchers conducted a study involving 1,000 families, they found that a link exists between people who carry this variation of the gene and people who have heart disease or a family history of the disorder.
