摘要
目的探讨血管内皮生长因子(VEGF)基因多态性与室间隔缺损(VSD)发病风险的相关性。方法选取2013年1月至2014年12月首都医科大学附属北京安贞医院小儿心脏中心收治的汉族单纯VSD患儿68例为VSD组,另选同期住院的汉族非先天性心脏病患儿78例为对照组。应用聚合酶链反应结合DNA测序技术,对2组患儿VEGF基因的5个位点(-2578C〉A、-460T〉C、-1154G〉A、+405G〉C、+936C〉T)进行突变检测,并对其单核苷酸多态性进行基因分型,分析单个位点的等位基因和基因型频率是否与VSD有关。结果+405G〉C位点的G/G基因型(比值比=0.31,95%置信区间:0.14~0.67,P〈0.01)是VSD患儿的一个保护效果基因型;+405G〉C位点的C/C基因型(比值比=2.69,95%置信区间:1.07~6.77,P〈0.05)是VSD患儿的一个易感基因型。-1154G〉A位点的A碱基型(比值比=0.41,95%置信区间:0.23~0.76,P〈0.01)和+405G〉C位点的G碱基型(比值比=0.47,95%置信区间:0.29~0.75,P〈0.01)是VSD患儿的保护效果单倍型;+405G〉C位点的C碱基型(比值比=2.13,95%置信区间:1.33-3.40,P〈0.01)是VSD患儿的风险单倍型。结论VEGF基因的一1154G〉A位点和+405G〉C位点基因突变可能与VSD的发生有关。
Objective To investigate the relation between polymorphism of vascular endothelial growth factors(VEGF) gene and risk of ventricular septal defect (VSD). Methods Sixty-eight children of isolated VSD (VSD group)and 78 cases of non-congenital heart disease (control group)were enrolled from January 2013 to December 2014 in Beijing Anzhen Hospital, Capital Medical University. Potymerase chain reaction and DNA sequencing technique were used to detect 5 loci of VEGF gene ( - 2578C 〉 A, - 460T 〉 C, - ll54G 〉 A, + 405G 〉 C, + 936C 〉 T). The polymorphism of VEGF gene was genotyped, effects of its allelic gene and genotypic frequency on the risk of VSD were analyzed. Results The G/G genotype of VEGF + 405G 〉 C had profeetive effect on VSD[ odds ratio(OR) = 0.31, 95% confidence interval (CI) = 0.14-0.67, P 〈 0.01 ) ; the C/C genotype of VEGF + 405G 〉 C had risk effect on VSD ( OR = 2.69, 95% CI = 1.07-6.77, P 〈 0.05 ), the C/C genotype was a predisposing genotype of VSD. The A haplotype of VEGF - 1154G 〉 A ( OR = 0.41, 95% C1 = 0.23-0.76, P 〈 0. 01 ) and G haplotype of VEGF + 405G 〉 C ( OR = 0.47, 95% CI = 0.29-0.75, P 〈 0.01 ) had positive effect on VSD ; the C haplotype of VEGF + 405G 〉 C had risk effect on VSD ( OR = 2.13,95% CI = 1.33-3.40, P 〈 0. O1 ), the C haplotype was a predisposing haplotype of VSD. Conclusion Genic mutations of VEGF - 1154G 〉 A and +405G 〉 C are related to the risk of VSD.
