title: CYP3A4 genotypes and plasma lipoprotein levels before and after treatment with atorvastatin in primary hypercholesterolemia.
abstract: To test whether genetic variation in the CYP system may influence the statin response, a promoter (A-290G) and 2 nonsynonymous polymorphisms (F189S and M445T) in the CYP3A4 gene locus were examined in 340 hypercholesterolemic patients who were treated with atorvastatin 10 mg. The A-290G variant allele was significantly associated with higher levels of post-treatment low-density lipoprotein cholesterol, whereas the M445T variant was associated with lower levels of low-density lipoprotein cholesterol before and after treatment.
