Objective To explore the correlation between the gene polymorphism of glucocorticoid receptor intron 4 G1666T (GR G1666T) and intracerebral hemorrhage(ICH ).Methods Frequencies of genotypes and alleles of GR G1666T in 48 pations with ICH(ICH group),48 ICH patients combining essential hypertension(EH) (ICH+EH group),46 EH patients (EH group) and 71 healthy people (NC group) were analyzed by a polymerase chain reaction for restriction fragment length polymorphism (PCR-RFLP).The gender,body mass index(BMI),blood pressure(BP),the levels of plasma angiotensinogen,renin,blood glucoseand and blood lipid were compared among the various genotype of GR G1666T in ICH patients.Results There was no obviously difference of G1666T genotype and allele frequencie among the 4 groups.However,the G allele frequence of females in groups ICH,ICH+EH and EH were significantly higher than that in NC group(all P

Objective To identify the association between human glucocorticoid receptor gene G166T polymorphism and essential hypertension(EH).Methods DNA samples from 71 normotensive cases and 48 EH cases were analyzed by a polymerase chain reaction(PCR) for restriction fragment length polymorphism(RFLP) to determine the intron 4 variant of human glucocorticoid receptor gene.Results No association was observed between EH group and control group.However,in females,a little association was observed between the EH group and control group.Frequencies of allele G were 0.64 in EH group and 0.46 in control group.Conclusion The G allele may be a predisposing gene marker,HGR gene intron 4 polymorphism contributes to the development of EH in females.
