Dissecting the polygenic basis of atherosclerosis via disease-associated cell state signatures

Using single-cell RNA sequencing, researchers identified 12 atherosclerosis-associated cell states and found that Vcam1+ smooth muscle cell state contributed the most to the genetic heritability of coronary artery disease. A hybrid polygenic risk score (PRS) that considers cell-type-specific regulatory elements demonstrated improved performance over a classical PRS.
