目的 探讨广西地区parkin基因启动子区-258T/G多态性与散发性帕金森病(sporadicParkinson's disease,SPD)的相关性及该多态性与PD发病年龄的关系.方法 PCR-RFLP及DNA测序等技术,分析parkin基因-258T/G多态性在PD患者和健康对照者间分布频率的差异.结果 PD组parkin基因-258T/G多态性位点G等位基因频率显著高于正常对照组(55.20%:43.33%,x2=6.898,P<0.05,OR=1.61,95%CI:1.13~2.30);GG基因型频率显著高于对照组(28.00%:18.33%,x2=7.159,P<0.05,OR=2.75,95%CI:1.31-5.77).同时,TG+GG基因型频率亦显著高于对照组(82.40%:68.33%,x2=6.551,P<0.05,OR=2.17,95%CI:1.20~3.93).50岁及50岁以上发病患者G等位基因频率和GG基因型频率显著高于对照组,50岁以下发病患者各频率虽高于正常对照组但差异无统计学意义.结论 Parkin基因核心启动子区-258T/G多态G等位基因可能增加了广西地区PD发病风险,且与PD发病年龄成正相关.  相似文献

目的探讨PINK1基因第5外显子上游调控区IVS5-5G>A多态位点与散发晚发性帕金森病(Parkinson disease,PD)发病风险的关联性。方法对IVS5-5G>A多态位点是否可能影响mRNA剪接进行了生物信息学分析。采用病例-对照的方法对382例散发晚发性PD病例和336名匹配的对照进行了PINK1基因IVS5-5G>A多态与中国汉族人散发晚发性帕金森病的发病风险的关联研究。基因型分型采用聚合酶链反应,变性高效液相色谱和测序相结合的方法。等位基因频率和基因型频率分布差异的比较采用卡方检验。结果生物信息学分析内含子区IVS5-5G>A多态位点位于第5外显子剪接受点区域内,可能是影响基因表达的调控区功能性单核苷酸多态性。PINK1基因IVS5-5G>A多态性与中国人散发晚发性PD发病风险之间存在有统计学意义的相关性(OR=1.95,95%CI:1.29~2.94,P=0.0012)。携有A等位基因的纯合子(AA)发病风险明显增加(OR=2.45,95%CI:1.27~4.72,P=0.009)。结论研究结果证实PINK1基因IVS5-5G>A多态性可能是中国人晚发PD的一个危险因素。  相似文献

Objective To investigate the association between the-258T/G polymorphism.in the pro-moter of parkin gene and the risk for sporadic parkinson's disease (SPD) in Guangxi Province, and in relationto the age of onset, of PD patients. Methods PCR-RFLP and sequence analysis were used to determine thegenotype of-258T/G polymorphism between all patients and healthy controls. Results The G allele was morecommon in patients than controls (55.20%:43.33% ,x2=6.898, P<0.05, OR=1.61, 95% CI: 1.13 ~2.30). The frequency of GG genotype was higher in patients than in controls (28.00 %: 18.33%, x2=7.159, P<0.05, OR=2.75, 95% CI : 1.31 ~ 5.77). The frequency of TG + GG genotype was higher in pa-tients than in controls (82.40%:68.33%, x2=6.551, P<0.05, OR=2.17.95%CI: 1.20 ~3.93). Afterbeing stratified by onset age, the frequencies of the G allele and GG genotype were significantly higher in pa-tients with onset age over 50 years than those in controls respectively. On the other hand, the frequency was notsignificantly different between the younger onset PD patients and the controls. Conclusion The parkin promot-er-258T/G polymorphism might be a risk factor for PD in Guangxi Province, and the G allele was increasedwith increasing age.  相似文献

目的探讨亚甲基四氢叶酸还原酶(methylene tetrahydrofolate reductase,MTHFR)基因上C667T和A1298C多态位点与冠心病(coronary heart disease,CHD)的相关性,以及寻找冠心病的发病危险因素。方法随机选取行冠状动脉造影确诊的冠心病患者200例和同期同地区正常对照200例,运用Taqman方法对C667T和A1298C两个多态位点进行基因分型,罗氏生化和发光(Cobas8000)流水线来测定生化指标及血浆高同型半胱氨酸(homocysteine,HCY)、磷酯酶A2(phospholipase A2,PLA2)、血清叶酸水平等。结果冠心病组的体质量指数(body mass index,BMI)、收缩压(systolic pressure,SBP)、脂蛋白a(lipoprotein a,Lp a)、糖化血红蛋白(glycated hemoglobin,HbA1c)、磷脂酶A2、HCY水平均显著高于对照组;而总胆固醇(total cholesterol,TC)、低密度脂蛋白(LDL-C)、血清叶酸则显著低于对照组。对其进行单因素Logistic回归分析发现,除去上述变量,C667T多态位点也是冠心病发病的危险因素;进一步对C667T和A1298C两个多态位点进行分析时发现,C667T多态位点与冠心病存在相关性,冠心病组的T等位频率为39.0%,远高于对照组的22.0%(P=0.045);在显性模型中,CT/TT vs.CC的P值为0.029,OR=2.60,95%CI分别为1.03~6.14;不同基因型趋势检验P=0.016。而A1298C多态位点并未观察到其与冠心病存在相关性。在C667T和A1298C两个多态位点的联合单倍型分析中,发现只有当两个多态位点同时发生突变(T-G型)时,才存在统计学差异(P=0.034,OR=3.54,95%CI=1.10~11.41),单倍型的分布模式在病例和对照组之间有显著差异(P=0.037)。结论MTHFR基因上C667T多态位点与冠心病存在相关性,而A1298C多态位点并未观察到相关性,单倍型分析发现两者同时发生突变时可增加冠心病的发病风险。  相似文献

目的 上皮钙黏着蛋白(E—cadherin)的编码基因CDHI是重要的肿瘤抑制基因,本研究探讨CDH1基因-160(C→A)多态性在福建地区胃癌人群中的分布及其与福建地区胃癌发病风险的相关性。方法 采用聚合酶链反应-变性高效液相色谱分析方法对102例胃癌患者和101名正常对照者进行CDH1基因-160(C→A)多态的基因型分析,比较基因型分布和发病风险的关系;危险度OR及95%CI应用非条件Logistic回归分析计算。结果 CDH1基因-160(C→A)多态的CC、CA、AA基因型在病例组中的分印频率分别为58(56.9%).38(37.3%),6(5.9%);在对照组的分布频率分别为55(54.5%),41(40.6%),5(5%);两组间分布的差异无统计学意义(P〉0.05)。AA基因型没有显著性地提高或降低胃癌的发病危险(OR=1.12;95%CI:0.32~3.95);携带A等化基因与胃癌的临床病理特征也无关联性。结论 CDH1基因-160(C→A)多态性可能与福建地区中国人群胃癌发生的遗传易感性无关。  相似文献

目的:研究RUNX3基因C364T突变在我国胃癌高、低发区普通人群和胃癌患者中的分布,H.pylori感染者胃粘膜的RUNX3基因C364T突变率,探讨此突变与我国胃癌发生的关系。 方法: 采用PCR-限制性片段长度多态性(RFLP)分析法检测胃癌高发区169名普通人、86例胃癌患者和胃癌低发区192名普通人和92例胃癌患者的RUNX3基因多态性。同时比较胃癌低发区普通人胃粘膜H.pylori阳性和阴性者的RUNX3突变率。 结果: 在胃癌高、低发区,胃癌患者RUNX3基因C364T突变频率与普通人群无显著差异(χ2=0.57和0.16,P>0.05)。与肿瘤类型也无明显关系。低发区H.pylori阳性者粘膜中,RUNX3基因突变率也无显著增高。 结论: RUNX3基因C364T突变可能不是我国胃癌高、低发区胃癌的遗传易感因素。而且H.pylori感染导致胃癌形成可能不由RUNX3基因C364T突变参与。  相似文献
