Interindividual variability exists in statin lipid-lowering response, partially attributed to genetic factors. Organic anion-transporting polypeptide 1B1 (OATP1B1) encoded by SLCO1B1 gene (solute carrier organic anion transporter family member 1B1) facilitates hepatic uptake of simvastatin and atorvastatin. SLCO1B1 polymorphisms are strongly associated with statin-induced myopathy whereas few studies have assessed their effect on statin differential response. In the present study, we analyzed the association of SLCO1B1 521T>C, 388A>G and 411G>A polymorphisms with response to atorvastatin and simvastatin in 386 adults (201 atorvastatin-treated and 185 simvastatin-treated) with primary hypercholesterolemia, all of Greek origin. Total cholesterol and low-density lipoprotein cholesterol were measured at baseline and on 6 months of treatment. Genetic polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. A novel RFLP protocol was developed for the simultaneous identification of 388A>G and 411G>A polymorphisms. SLCO1B1 521T>C, 388A>G and 411G>A polymorphisms were not associated with lipid-lowering response to atorvastatin or simvastatin. No sex-gene or statin dose-gene interaction was observed on the effect of the analyzed SLCO1B1 polymorphisms in statin lipid lowering response in either statin-treated patient cohort. Further studies in different populations are required to draw firm conclusion on the potential association of SLCO1B1 polymorphisms with statin lipid-lowering response.
