Associations between polymorphisms of the ADIPOQ gene and hypertension risk: a systematic and meta-analysis.

ABSTRACT: ADIPOQ gene polymorphisms have been indicated to be associated with hypertension; however, published studies have reported inconsistent results. Eligible studies were retrieved by searching the PubMed, Embase and China National Knowledge Infrastructure databases. The case group consisted of patients with hypertension, and the control group consisted of subjects with normal blood pressure. Based on eleven published articles, involving 4837 cases and 5618 controls, the pooled results from rs2241766 polymorphism showed increased risk in the allelic model (G VS T: OR?=?1.16, 95%CI?=?1.06-1.27), recessive model (GG VS GT?+?TT: OR?=?1.34, 95%CI?=?1.10-1.63), dominant model (GG?+?GT VS TT: OR?=?1.15, 95%CI?=?1.02-1.30) and homozygote model (GG VS TT: OR?=?1.38, 95%CI?=?1.21-1.69). In addition, rs266729 polymorphism showed increased risk for hypertension in the recessive model (GG VS GC?+?CC: OR?=?1.43, 95%CI?=?1.02-2.01). In the Caucasian subgroup, rs1501299 polymorphism showed decreased risk of hypertension in the allelic model (T VS G: OR?=?0.75, 95%CI?=?0.58-0.97), dominant model (TT?+?TG VS GG: OR?=?0.83, 95%CI?=?0.71-0.98) and heterozygote model (TG VS GG: OR?=?0.82, 95%CI?=?0.68-0.99). The rs2241766 polymorphism was associated with a significant increase in hypertension risk based on our analysis. Moreover, an increased risk of rs266729 in hypertension patients was also detected. Our meta-analysis suggests that the rs1501299 polymorphism may play a protective role in hypertension in Caucasian subgroup; however, this finding requires further study.
