Three genes mutations in which cause familial forms of Alzheimer's disease are known to date:PSEN1, PSEN2 and APP; and APOE gene polymorphism is a strong risk factor for Alzheimer's disease. We have evaluated allele and genotype frequency distribution of rs11136000 polymorphism in clusterin (CLU) gene (or apolipoprotein J, APOJ) in populations of three Russian regions and i nAlzheimhner's diseasepatients. Genome-wideassociation studies in samples from several European populations have recently revealed highly significant association o fCLU gene with AD (p = 8.5 x 10(-10)). We found no differences in allele and genotype frequencies of rs11136000 between populations from Moscow, Ural and Siberia regions. The allele frequencies are close to those in European populations. The genetic association analysis in cohort of Alzheimer's disease patients and normal individuals (500 individuals ineach group) revealed no significant association of the rs11136000 polymorphism in CLU with Alzheimer's disease in Russian populations. Although our resultsdo not confirm the role of CLU gene as a majorgenetic factor forcommon form of Alzheimer's disease, the data do not rule out the possibility of modest effect of CLU and interaction between CLU and APOE genotypes in etiology of Alzheimer's disease.
