The association of single nucleotide polymorphism of the Fyn gene with sporadic Alzheimer's disease in the Chinese Han population.
Recent studies suggested genetic factors contribute to the pathogenesis of sporadic Alzheimer's disease (sAD). Fibroblast Yes related novel (Fyn), a tau kinase, has been reported to be associated with aberrant phosphorylated tau and neurofibrillary tangles formation. Fyn gene may be a potential candidate gene for AD. To investigate the association of the polymorphisms in Fyn gene with the susceptibility to sAD, we conducted a case-control study in a Chinese Han cohort including 200 sAD patients and 243 control participants. Four single nucleotide polymorphisms (SNPs) (rs111787668, rs1057979, rs6916861 and rs12910) within the promoter region of Fyn gene and one (rs7768046) in intron were selected and genotyped with a polymerase chain reaction-ligase detection reaction (PCR-LDR) method. Logistic regression under four genetic models was used to analyze the association between target SNPs and the risk of sAD. After adjusting for age, sex and APOE ɛ4 status, no association was revealed between these SNPs or the haplotypes containing four SNPs and the risk of sAD (P>0.05). The SNPs in the selected regions of the Fyn gene are unlikely to confer the susceptibility of sAD in the Chinese Han population. Further studies with a larger sample size and different ethnic populations are needed to reveal the role of Fyn gene in the pathogenesis of sAD.
