成纤维细胞生长因子1基因启动子多态性与晚发型阿尔茨海默病的相关性研究

目的探讨成纤维细胞生长因子1（FGF-1）基因启动子多态性是否与晚发型阿尔茨海默病（LOAD）相关.方法收集206例尸体检查的样本,包括100例LOAD和年龄匹配的对照组106例.PCR-RFLP（Restriction fragment length polymorphism）法分析FGF-1基因启动子（-1385 A/G）的基因型.结果FGF-1基因启动子（-1385 A/G）的基因型频率分布是：AA型20例（10%）,GA型89例（43%）,GG型97例（47%）,在LOAD组和对照组之间,不同基因型频率分布有显著性差异（P=0.027）;GG基因型与LOAD呈正相关（odds ratio-2.02,95%CI：1.16～3.52）.结论FGF-1基因启动子（-1385 A/G）多态性与LOAD显著相关.

Correlation between the Promoter Polymorphism of Fibroblast Growth Factor 1 gene and Late-onset Alzheimer''''s Disease

ObjectiveTo evaluate the correlation between the promoter polymorphism of Fibroblast Growth Factor 1 (FGF-1) and late-onset Alzheimer's disease (LOAD). MethodsClinic pathological data from 206 autopsies were analyzed, including 100 autopsy-confirmed LOAD patients and 106 age-matched non-demented controls. PCR-RFLP (Restriction fragment length polymorphism) approach was used to determine the genotype of the promoter polymorphism of FGF-1 gene. ResultsThe genotyping frequencies of the promoter polymorphism (-1385 A/G) were AA 20 (10%), GA 89 (43%), GG 97 (47%), respectively. There was significant (P=0.027) difference of genotyping frequencies between the cases and controls; GG genotype was positively associated with LOAD (odds ratio=2.02, 95%CI:1.16~3.52). ConclusionThe promoter polymorphism (-1385 A/G) of FGF-1 gene was associated with LOAD.
