Background: Many studies have evaluated the association between aldosterone synthase (CYP11B2) C-344T polymorphism and preeclampsia (PE) susceptibility, however, the results from different studies are inconsistent.
Objective: The study aimed to derive a more precise estimation of this association.
Methods: We searched PubMed, Embase, Chinese National Knowledge Infrastructure, China Biological Medicine, and Wanfang Database. The association was evaluated by calculating the odds ratios (ORs) with the corresponding 95% confidence intervals (CIs).
Results: Seven case-control studies with a total of 720 cases and 766 controls were eligible to be included in this meta-analysis. Overall, there was no significant association between CYP11B2 C-344T polymorphism and PE (for the allele model T vs.C: OR=0.78, 95%CI 0.60-1.01, p=0.06; for the codominant model CT vs. CC: OR=1.08, 95%CI 0.80-1.46, p=0.63; for the dominant model TT + CT vs. CC: OR=0.91, 95%CI 0.68-1.20, p=0.49). Similar results were obtained in sensitivity analysis.
Conclusion: In summary, the present meta-analysis suggests that CYP11B2 C-344T polymorphism may not be associated with genetic susceptibility of PE, but the association remains indeterminate due to the insufficient evidence.

The purposes of the research were to study the prevalence of C-344T polymorphism and the distribution of aldosterone synthase gene (CYP11B2) genotypes, to analyze the association of aldosterone concentration with aldosterone synthase gene genotypes, to study the features of left ventricular hypertrophy (LVH) by echocardioscopy and identify their association with different genotypes of the aldosterone synthase gene in young patients with arterial hypertension (AH), depending on the presence or absence of concomitant obesity (or overweight). 123 young patients with essential AH (18-44 years old) were examined, the average age was (32,83±0,58) years old, the male/female ratio was 72/51 respectively. All patients were divided into 3 groups: group 1 (n=41) with normal body weight; group 2 (n=40) with overweight; group 3 (n=42) -with obesity.

Introduction: The exact cause of preeclampsia (PE) remains elusive. Recently, many researchers have focused on the role of genetic variations in pathogenesis of PE. The renin-angiotensin-aldosterone system is affected in the pathogenesis of PE.

Background: Aldosterone synthase (CYP11B2) is a key enzyme involved in the terminal steps of aldosterone biosynthesis. Genetic variability in CYP11B2 gene has been associated with heterogeneous aldosterone production, which can affect sodium homeostasis and thereby regulation of blood pressure. Hence, the present study was aimed to explore the single-locus variations, haplotype and epistasis patterns of CYP11B2 (C-344T, intron-2 gene conversion and Lys173Arg) gene polymorphisms, and the risk contributed by them to the development of essential hypertension (EHT).

Essential hypertension (EH) is a complex multifactorial condition influenced by both genetic and environmental factors; aldosterone synthase (CYP11B2) is a key enzyme which involves in the terminal steps of aldosterone synthesis. The result of relationship between C-344T of CYP11B2 polymorphism and EH was controversial. This study was undertaken to investigate the association of C-344T polymorphism with EH in the populations of Tibetan, Dongxiang and Han from northwest of China.
