Abstract
Several lines of evidence indicate that fibroblast growth factor 1 (FGF1) confers neuroprotection against excitotocity and contributes to the selective vulnerability of neurons in entorhinal cortex in Alzheimer's disease (AD). Especially, FGF1 is related to Apolipoprotein E (ApoE) expression in reactive astrocytes. Therefore, FGF1 is a promising candidate gene for AD. Two studies reported the association of a polymorphism that is located 1385bp upstream from the initial code of FGF1 gene (FGF1 −1385 C>T) polymorphism with AD. To determine whether this polymorphism could affect AD development, we investigated the association between this polymorphism and AD risk in 372 sporadic AD patients and 349 controls in a Chinese Han population. No significant difference of allele and genotype distributions between the AD cases and the controls was observed in the total samples (for the alleles, χ2=0.126; p=0.722; for the genotypes, χ2=0.089; p=0.765), neither when the samples were stratified by ApoE ε4-carrying status, age/age at onset and gender. Our data suggested no association between the FGF1 −1385 C>T polymorphism and AD risk in Chinese Han population.
