Objective:
To assess the relationship between the polymorphisms of leptin receptor gene and hypertension.
Methods:
Meta analysis was conducted by using RevMan 5.3. Relevant literatures were retrieved by searching PubMed using the keywords "Hypertension", "Leptin Receptor", "OB Receptor", "LEPR Protein".
Results:
Fifteen studies with a total of 5955 patients with hypertension and 3830 healthy controls were included in this meta-analysis. The results showed that Gln223Arg gene polymorphism was significantly higher in hypertension patients than in control (OR=1.36, 95% CI=1.23-1.51, P<0.00001). However, no statistically significant difference was found in Lys109Arg polymorphism between hypertension patients and control (OR=0.99, 95% CI=0.85-1.16, P=0.91).
Conclusion:
Gln223Arg, but not Lys109Arg gene polymorphism, is higher in hypertension patients, suggesting that patients with Gln223Arg allele carry a higher risk to develop hypertension.
