Rare Genetic Variants in LDLR , APOB , and PCSK9 Are Associated With Aortic Stenosis

CirculationPublished Genetic association study

Authors' conclusion

Rare genetic variants that confer lifelong higher or lower LDL-C levels are associated with substantially increased and decreased risk of AS, respectively.
