alpha-Adducin gene G614T polymorphisms in essential hypertension patients with high low density lipoprotein (LDL) levels

摘要

Background & objectives'. The association between a-adducin gene G614T polymorphism and essential hypertension (EH) is not clear. The present study was carried out to examine a possible association between a-adducin gene G614T mutation and essential hypertension in Chinese population.Methods: A total of 170 patients with essential hypertension (EH group) and 154 normotensive subjects (Control group) were genotyped for the cytoskeletal protein single nucleotide polymorphism G614T of the a-adducin gene by PCR-RFLP technique. Systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), low density lipoprotein (LDL), high-density lipoprotein (HDL), high-sensitivity C-reactive protein (hs-CRP), left atrial diameter (LA DIA), left ventricular diameter (LV DIA) and other parameters were recorded in EH group.Results: There was significant association between EH and a-adducin genotypes (P<0.05). GT and TT genotypes in EH group had higher LDL levels as compared to GG carriers (P<0.05). The LDL concentration was significantly elevated in patients with GT and TT genotypes. The LDL levels also differed significantly in male patients with all the three genotypes.Interpretation & conclusions: A significant association was found between ADD1 gene G614T polymorphism and EH in Chinese patients. Further studies need to be done to confirm these findings in a large sample.
