Association of Renalase SNPs rs2296545 and rs2576178 with the Risk of Hypertension: A Meta-Analysis

Abstract

Background/AimsTwo renalase single nucleotide polymorphisms (SNPs) rs2296545 and rs2576178 have been reported to be associated with the susceptibility to hypertension (HT). Given the inconsistent results, we conducted a meta-analysis to assess the association between these two SNPs and the risk of HT.MethodsElectronic databases were systematically searched to find relevant studies. Subgroup analysis was conducted according to the different concomitant diseases and ethnicities in the study population. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated using fixed-effect or random-effect models.ResultsA total of six case–control studies on rs2296545 and six studies on rs2576178 were included. In the combined analysis, results showed a significant association between SNP rs2296545 and risk of HT in all genetic models (dominant model CG+CC/GG: OR = 1.43, 95% CI = 1.24–1.65; recessive model CC/CG+GG: OR = 1.36, 95% CI = 1.09–1.69; codominant model CC/GG: OR = 1.63, 95% CI = 1.20–2.20, CG/GG: OR = 1.30, 95% CI = 1.12–1.52; allelic model C/G: OR = 1.29, 95% CI = 1.10–1.51). In subgroup analysis, we observed a significant association between rs2296545 and risk of essential HT. Although we did not observe an association between rs2576178 polymorphism and HT in the combined analysis, an increased risk was observed in the essential HT patients versus healthy controls (subgroup 1) analysis under the dominant, recessive, and codominant genetic models.ConclusionsRenalase gene rs2296545 polymorphism is significantly associated with increased risk of HT, whereas rs2576178 polymorphism may not be associated with the susceptibility to HT.

Renalase — a potential biomarker for risk of atrial fibrillation?

“…Such an expression pattern would be in line with its postulated mode of action to degrade circulating catecholamines and links it to the regulation of sympathetic nervous system activity [8]. Although there has been some doubt in the literature on the "true" function of renalase [9], a number of studies showed its negative association with blood pressure [10,11].…”

Age influence on renalase and catecholamines concentration in hypertensive patients, including maintained dialysis

“…Stec et al19 found that renalase gen polymorphism was associated with a higher risk of hypertension in patients with CKD-maintained dialysis. In the most recent meta-analysis, Lv et al33 reported that renalase gene rs2296545 polymorphism is significantly associated with an increased risk of hypertension, whereas rs2576178 polymorphism may not be associated with the susceptibility to hypertension. On the other hand, the result of the recent study of Kiseljakovic et al20 suggested that renalase gene polymorphism was not a factor that influenced BP in patients on HD.…”
