PCSK9 R46L

(PCSK9 Arg46Leu)


Short summary

This variant is reported to have a dominant protective effect against coronary heart disease. Carriers of this variant have about half the risk of coronary heart disease compared to non-carriers (6.3% risk in carriers vs. 11.8% risk in non-carriers).

While nonsense variants were found in black subjects and associated with decreased risk of coronary heart disease (CHD), these were very rare in white subjects. R46L was found in white subjects and was associated with a 15 percent reduction in LDL cholesterol and a 47 percent reduction (6.3 percent vs. 11.8 percent) in the risk of CHD (hazard ratio, 0.50; 95 percent confidence interval, 0.32 to 0.79; P=0.003).
