Association of FTO , KCNJ11 , SLC30A8 , and CDKN2B polymorphisms with type 2 diabetes mellitus

To test FTO, KCNJ11, SLC30A8, and CDKN2B for association with type 2 diabetes mellitus (DM), the allele and genotype frequency distributions were established for several polymorphisms of the genes. A comparison of allele and genotype frequencies between DM patients and healthy subjects implicated CKNJ11, SLC30A8, and CDKN2B, but not FTO, in the disease. The genes that affect insulin production and secretion in pancreatic β cells proved to play a main role in type 2 DM in the Russian population.
