Impact of 3'UTR genetic variants in PCSK9 and LDLR genes on plasma lipid traits and response to atorvastatin in Brazilian subjects: a pilot study.

ABSTRACT:

Background

Hypercholesterolemia is a complex trait, resulting from a genetic interaction with lifestyle habits. Polymorphisms are a major source of genetic heterogeneity, and variations in 2 key cholesterol homeostasis genes; low-density lipoprotein receptor (LDLR) and proprotein convertase subtilisin/kexin type-9 (PCSK9), lead to dyslipidemia. So, we investigated the relation of 2 variants located in the 3'-UTR (3'-untranslated region) of LDLR (rs14158, G>A) and PCSK9 (rs17111557, C>T) with lipid profile and atorvastatin response.

Methods

SNP influence on lipid profile was assessed in hypercholesterolemic patients (HC; n = 89) using atorvastatin (10 mg/day/4 weeks) and in normolipidemic subjects (NL; n = 171). Genotyping was completed through real-time PCR using TaqMan assa
