Association of the polymorphisms of the TCF7L2 genes with type 2 diabetes

To study the association with diabetes mellitus type 2 we performed analysis of the distribution of frequencies of alleles and genotypes two polymorphic markers of TCF7L2 gene. The study included groups of T2DM patients and unrelated controls of Russian origin. Analysis of the distribution of frequencies of alleles and genotypes of the polymorphic marker rs7903146 of TCF7L2 gene showed the presence of association with T2DM in Russian population, while for the marker rs12255372 was not found statistically significant associations with type 2 diabetes. We can conclude that in Russian population TCF7L2 gene is associated with development of T2DM.
