NIH-led study finds genetic markers that explain up to 12 percent of the differences between two people’s blood pressure

National Institutes of Health researchers and collaborators have discovered over 100 new regions of the human genome, also known as genomic loci, that appear to influence a person’s blood pressure. Results of the study also point to several specific genomic loci that may be relevant to iron metabolism and a type of cellular receptor known as adrenergic receptors.

The study, published in Nature Genetics, is one of the largest such genomic studies of blood pressure to date, including data from over 1 million participants and laying the groundwork for researchers to better understand how blood pressure is regulated. Such insights could point to potential new drug targets.

“Our study helps explain a much larger proportion of the differences between two people’s blood pressure than was previously known,” said Jacob Keaton, Ph.D., staff scientist in the Precision Health Informatics Section within the National Human Genome Research Institute’s (NHGRI) Intramural Research Program and first author of the study. “Our study found additional genomic locations that together explain a much larger part of the genetic differences in people’s blood pressure. Knowing a person's risk for developing hypertension could lead to tailored treatments, which are more likely to be effective.”
