Genetics and Heart Disease

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.
