Additionally, the study found that gene-drug interactions can also influence the predictive power of a genetic risk tool known as a polygenic score.

Importantly, the researchers also developed a polygenic risk score to assess a person's likelihood of developing dilated cardiomyopathy based on the many small effects of these genes.

Although the approach, known as polygenic embryo screening, is not yet available in most IVF clinics, a few companies have begun offering such estimates -- or risk scores -- to gauge disease risk, the researchers noted.

These tests rely on polygenic scores -- a tally of variations in human genes that influence a certain trait.

The findings lead to improved polygenic risk scores, which will better predict blood pressure and risk for hypertension.
