Genetic and methodological aspects of statin-induced lipid response

Abstract

This thesis examines how both genetic and more

conventional epidemiological endeavors may complement research into effects

of statin therapy. These include a pharmacogenetic GWAS meta-analysis on

statin-induced HDL-C response by the Genomic Investigation of consortium, which identified CETP as a loci of interest, and two-sample Mendelian randomization studies utilizing summary level data from the GIST and other GWAS consortia on fasted blood lipids and type 2 diabetes. We additionally examine the issue of survival bias in Mendelian randomization studies. Finally, we show that intra-individual lipid variability associates with worse neurocognitive outcomes in older individuals at high risk for vascular disease, discuss its interplay with lipid-lowering treatment, and describe the literature regarding genetic factors of possible interest.
