| Popis: | Objectives To look at the possible effect of IGF2R rs9456497 on cardiovascular risks in a long-lived population. Methods IGF-2R rs9456497 was genotyped by iMLDR for 496 long-lived Zhuang Chinese (90–107 y/o) and their offspring (n = 723, 60–75 y/o) and healthy controls (n = 611, 60–75 y/o). Association analyses were then conducted among genotypes and cardiovascular risks. Results The G genotype (GA/GG) was found to represent more frequently in males of general population. No significantly difference was detected among genotypes in each group except that G genotype tended to reduce the systolic blood pressure (SBP) and diastolic blood pressure (DBP) levels in longevity group. However, after sex stratification, total cholesterol (TC) of each genotype in offspring males was elevated versus relevant genotype in longevity and control group; the triglyceride (TG), fasting plasma glucose (FPG) and BMI of each genotype in longevity group were lower while SBP and DBP were higher than that of the relevant genotype in offspring and controls. After stratified by lipid status, the frequency of G allele was markedly increased in the dyslipidemic subgroup in the combined population and controls. Linear regressive analyses showed that HDL was positively correlated to rs9456497 GA genotype while BMI was negatively correlated to AA genotype in offspring group, whereas TC and TG were reversely while BMI was positively associated with AA genotype in CG. Conclusions IGF-2R rs9456497 G genotype correlates to detrimental cardiovascular risks in ordinary population which might partially interpret their less preservation of health as compared to long-lived cohort. |
