目的 探讨葡萄糖激酶调节蛋白(GCKR)基因rs780094 的多态性与儿童青少年血脂水平的关系。方法 选取1 026 名7~18 岁中小学生为研究对象。由专职人员记录学生一般情况和既往病史,检测身高、体重,并采集清晨空腹肘静脉血,测定血清TC、TG、HDL-C和LDL-C水平。利用基质支持的激光释放/电离飞行时间质谱分析(MALDI-TOF MS)进行GCKR 基因rs780094 位点的基因型检测。采用多元线性回归和多元logistic 回归分析基因多态性与血脂水平的关系。结果 调整年龄、年龄的平方和性别,GCKR基因rs780094 多态性A等位基因与TC、TG和LDL-C 的水平增加存在相关性(b=0.06 mmol/L,P=0.037;b=0.09 mmol/L,P<0.001;b=0.05 mmol/L,P=0.040);rs780094 多态性与TG、LDL-C 异常也存在相关性(OR=1.60,95%CI:1.30~1.97,P<0.001;OR=1.35,95%CI:1.02~1.80,P=0.036)。结论 GCKR 基因rs780094 位点的多态性与儿童青少年血脂水平有关,A等位基因可能是血脂增高的遗传因素。 |

Objective To investigate the association between rs780094 polymorphism in glucokinase regulatory protein(GCKR) and plasma lipid levels in children and adolescents. Methods 1 026 Chinese children aged 7 to 18 years were recruited,with anthropometric measurements,detection of plasma lipid levels and genotyping of rs780094 performed. Relationships between polymorphism and plasma lipid levels were tested,using multivariate linear regression and logistic regression. Results A-allele of rs780094 in GCKR was associated with increased TC,TG and LDL-C levels(b=0.06 mmol/L,P=0.037;b=0.09 mmol/L,P<0.001;b=0.05 mmol/L,P=0.040) under the additive model adjusted for age,age square and gender. The rs780094 in GCKR was also associated with abnormal levels of TG and LDL-C(OR=1.60,95% CI:1.30-1.97,P<0.001;OR= 1.35,95%CI:1.02-1.80,P=0.036). Conclusion The rs780094 in GCKR was associated with plasma lipid levels in children and adolescents while A-allele of rs780094 might serve as genetic factor for the increased plasma lipid levels. |
