PCSK9 and epilepsy: We conducted a drug-target Mendelian randomization study to examine the effects of genetically predicted inhibition of 3 established lipid-lowering targets (3-hydroxy-3-methylglutaryl coenzyme A reductase [statins], Niemann-Pick C1-Like 1 [ezetimibe], and proprotein convertase subtilisin/kexin type 9 [PCSK9 inhibitors]) on epilepsy and its subtypes.
