Association of rs12255372 (TCF7L2) and D76N (PDX-1) Polymorphisms with Type 2 Diabetes in a Population Living in Northeast Iran.

The aim of this study was to investigate whether the rs12255372 (TCF7L2) and D76N (PDX-1) polymorphisms are associated with type 2 diabetes mellitus (T2DM) in Mashhad, northeast Iran. A hundred twenty seven patients with T2DM and 71 non-diabetic controls in Mashhad were genotyped by PCR-RFLP and ARMS-PCR methods. Single nucleotide polymorphisms (SNPs) were confirmed by sequencing in some samples and allelic and genotypic frequencies were then analyzed in each group.
