New study has identified more than 500 new gene areas that influence people's blood pressure, a significant risk factor for stroke and heart disease. The findings of the study are published in the journal Nature Genetics. While lifestyle risk factors are relatively well-known and include obesity, smoking, alcohol, and high salt intake, high blood pressure is also highly heritable through genetics.
‘Newly-discovered gene regions by a research team could help assess a person's genetic risk score for high blood pressure in later life.’

The study, led by Queen Mary University of London (QMUL), analyzed the DNA of more than one million people, and the results more than triple the number of genetic regions linked to blood pressure to over 1,000. The findings suggested that all of the genetic variants raise a person's risk of high blood pressure by 3.34 times.
They also make an individual 1.52 times more likely to suffer a related complication, such as a heart attack or stroke.
Some of the newly-discovered gene regions are also involved in other diseases and could, therefore, be treated with existing drugs.
"With this information, we could calculate a person's genetic risk score for high blood pressure in later life," said Mark Caulfield, Professor at the QMUL.

The study also reports a strong role of these genes, not only in blood vessels, but also within the adrenal glands above the kidney, and in body fat.
