E670G polymorphism of PCSK9 gene of patients with coronary heart disease among Han population in Hainan and three provinces in the northeast of China.

Abstract：

OBJECTIVE:To investigate the correlation between E670G polymorphism of proprotein convertase subtilisin/kexin type 9 (PCSK9) gene and coronary heart disease (CHD), and contrastively study the regional differences of E670G polymorphism of PCSK9 gene between patients with CHD among the Han population in Hainan and three provinces in the northeast of China (TPNC), providing scientific basis for prevention and treatment of patients with CHD in different regions. METHODS:A total of 233 cases of patients with CHD were selected from the Han population in Hainan and TPNC as the experimental group (118 cases from Hainan, 115 cases from TPNC), and 239 cases with non-CHD were selected among the Han population also in the two regions as control group (125 cases from Hainan, 114 cases from TPNC). The triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol and low density lipoprotein cholesterol (LDL-C) levels of plasma were tested and PCR-RFLP method was used to test the E670G polymorphism of PCSK9 gene. The statistical software package SPSS 21.0 was used for the statistical analysis and P < 0.05 was considered as statistically significant. RESULTS:The levels of systolic pressure, diastolic blood pressure, fasting blood sugar, TC, TG, and LDL-C of patients in CHD group were significantly higher than those in non-CHD group, while the high density lipoprotein cholesterol level was lower than that in non-CHD group (P < 0.05). In CHD group, the frequencies of AG, GG genotypes of PCSK9 gene and G allele were higher than those in non-CHD group (P < 0.05), and in CHD group, the frequencies of AG, GG genotypes and G allele of patients both in Hainan and TPNC were higher than those in control group (P < 0.05). Among the patients with CHD, the frequencies of GG genotype and G allele of patients in Hainan were lower than those in TPNC (P < 0.05), and in CHD group, the levels of TG, TC and LDL-C of GG genotype were higher than those of AA genotype (P < 0.05). While in non-CHD group, there were no significant differences between the frequencies of GG genotype and G allele of patients in Hainan and TPNC (P > 0.05). CONCLUSIONS:There was a close correlation between the E670G polymorphism of PCSK9 gene and CHD with serum lipid level. Among Han population in Hainan and TPNC, the E670G polymorphism of PCSK9 gene of patients with CHD exhibited regional differences.
