Summary

This study will perform a genome-wide association study (GWAS) of the lipid responses to rosuvastatin and simvastatin and plasma concentrations of these two statins in a homogeneous group of Han Chinese patients.

Detailed description

A GWAS will be performed on about 360 Han Chinese patients with hypercholesterolaemia (which may be familial or non-familial) who have previously participated in a research project on the pharmacogenetics of statins and who have been treated with rosuvastatin and simvastatin to determine the genetic factors that may be related to the reduction in plasma low-density lipoprotein cholesterol (LDL-C) and plasma concentrations of these two statins. The lipid profiles were measured at baseline on no lipid-lowering treatment and after 4-6 week treatment of rosuvastatin 10 mg daily and after treatment with simvastatin 40 mg daily for at least 6 weeks with at least a 4-week washout period between the two treatments. Plasma concentrations of these two statins and their active metabolites about 12 hours after administration of statins have been measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Genotyping for the whole-genome scan will be carried out on the Illumina OminiExpress beadchip (Illumina, San Diego, CA). The samples will be processed using the Illumina iScan platform at the Li Ka Shing Institute of Health Science, The Chinese University of Hong Kong (CUHK).
