Interleukin-6 promoter polymorphism and late-onset Alzheimer's disease in the Finnish population

J Neurogenet. Jul-Dec 2005;19(3-4):155-61. doi: 10.1080/01677060600569721.


Recently, the involvement of the inflammatory response in Alzheimer's disease (AD) has received considerable attention. The gene encoding for interleukin-6 (IL-6) is interesting since IL-6 has been reported not only to be involved in immune functions but also in AD. We investigated whether the IL-6-174 G/C polymorphism is associated with late onset AD (LOAD) in the Finnish subjects. The G allele was over-represented in ApoE4-LOAD patients but remained unimportant in all and in the ApoE E4 carriers. Interestingly, the G allele frequency was lower in our population in both AD patients and in controls compared to Southern European populations.
