Article Abstract
Objective: To study whether CETP TaqIB,KCNE1 S38G and eNOS T-786C genetic polymorphisms are associated with non-valvular atrial fibrillation in the Han population from Zhejiang province.
Methods: Polymerase chain reaction restriction fragment length polymorphism assay was used to detect the distribution of alleles and genotypes of CETP TaqIB, KCNE1 S38G and eNOS T-786C in 147 patients with non-valvular atrial fibrillation and in 147 subjects as controls in Han population of Zhejiang province.
Results: (1) The frequency of CETP B1 allele in NVAF patients was higher than that of the control group and showing a statistically significant difference (OR = 1.763, 95% CI: 1.247-2.492, P = 0.002). (2) Results from logistic regression analysis revealed that: after adjustment of confounding variables such as sex, age, smoking, hypertension and body mass index, data from the binary logistic analysis showed a statistically significant difference in CETP TaqIB genetic polymorphism between patients and controls. (3) From multifactor dimensionality reduction analysis, results showed an interaction of CETP TaqIB, KCNE1 S38G and eNOS T-786C genetic polymorphisms. Odds ratio of the three simultaneously existing genetic polymorphisms was 1.849 times more than CETP TaqIB alone.
Conclusion: CETP BI allele was an independent risk factor for predisposition to non-valvular atrial fibrillation. These findings suggested that the simultaneous existence of CETP B1, KCNE1 S38G and eNOS T-786C allele might be elevated with the predisposition to non-valvular atrial fibrillation in the Han population of Zhejiang province.

Article Synopsis
- The study investigated the link between CETP Taq1B polymorphism and coronary artery disease risk factors, particularly how dietary patterns might influence this relationship.
- It involved 453 participants who provided dietary information through a detailed questionnaire, with two main dietary patterns identified: Western and Traditional.
- Results indicated that greater adherence to the Traditional Dietary Pattern (TDP) significantly affected triglyceride levels and the TG/HDL-C ratio based on Taq1B genotypes, suggesting that diet may play a role in managing lipid profiles for those with specific genetic variations.

Article Synopsis
- - The study reviews how gene-diet interactions impact cardiovascular diseases (CVD) by analyzing research conducted up until June 2022, focusing on various types of studies, including randomized controlled trials and cohorts.
- - A total of 59 articles were included where 35.6% were deemed high quality; the studies examined 50 dietary factors and 52 genetic variants, highlighting alcohol intake and ADH1C variants as key focuses.
- - Out of 266 tested interactions between diet and genetics, only 18.8% were statistically significant, with some inconsistencies in findings, indicating that while certain gene-diet effects exist, they may vary across studies.
No association between LDL receptor and genetic variants and atorvastatin response in Jordanian hyperlipidemic patients.

Objectives: Atorvastatin is commonly used medication to achieve low levels of low-density lipoproteins (LDL). Cholesteryl ester transfer protein () and LDL receptor () genetic variants can affect the cholesterol transport and hence may affect on atorvastatin response. This study aimed to investigate the influence of LDLR , and on the efficacy of 20 mg atorvastatin among Jordanian hyperlipidemic patients.

Purpose Of Review: An abnormal lipid profile is considered a main risk factor for cardiovascular diseases and evidence suggests that single nucleotide polymorphisms (SNPs) in the cholesteryl ester transfer protein (CETP) gene contribute to variations in lipid levels in response to dietary intake. The objective of this review was to identify and discuss nutrigenetic studies assessing the interactions between CETP SNPs and dietary factors on blood lipids.
Recent Findings: Relevant articles were obtained through a literature search of PubMed and Google Scholar through to July 2021.
The combined effects of cholesteryl ester transfer protein () TaqIB gene polymorphism and canola, sesame and sesame-canola oils consumption on metabolic response in patients with diabetes and healthy people.

Cholesteryl ester transfer protein (CETP) is a key regulating enzyme in the lipid metabolism pathway, and its gene polymorphism may be a candidate for modulating the metabolic responses to dietary intervention. We thus examined whether the effects of the CETP TaqIB polymorphism on metabolic profiles were modified by dietary plant oils. This is a retrospective analysis of data collected during a randomized triple-blind cross over trial.
