Should polygenic risk scores be used in risk-stratified colorectal cancer screening?

Polygenic risk scores (PRS) summarize information about a person’s disease risk based on numerous DNA variants in their genome. Each variant confers very little increase in disease risk. But composite (or polygenic) risk scores made up of a number of such variants have been shown to stratify people to normal distributions of disease risks for Read More >

The use of polygenic risk scores in clinical practice can exacerbate health disparities in ethnic and minority populations

This blog is a summary of our recent commentary on polygenic risk scores (PRS). PRS provide a rapidly emerging example of precision medicine and are based on multiple gene variants that each have weak associations with disease risks, but collectively may enhance disease predictive value in the population. The added value of PRS is unclear Read More >

In case you have not been paying much attention to genomic medicine research or social media coverage, you might have missed a clear uptick in the past couple of years  on the value of polygenic risk scores in clinical practice and population screening. (see examples here, here, here, and here) Polygenic risk scores (PRS) summarize Read More >

Research on the Behavioral Impact of Polygenic Risk Scores: The Train Has Already Left the Station!

There has been a lot of discussion recently about the new generation of polygenic risk scores (information about a person’s disease risk based on many dozens, hundreds, thousands, or even millions of common DNA variants in their genome), and whether these new-and-improved genetic risk scores are going to turn out to be useful for disease Read More >
