rs11927381 Polymorphism and Type 2 Diabetes Mellitus: Contribution of Smoking to the Realization of Susceptibility to the Disease.

In the study that included 579 patients with type 2 diabetes mellitus and 542 healthy individuals from Slavonic population, an association was found between IGF2BP2 gene rs11927381 polymorphism and increased risk of developing the disease. However, this association was observed for smoking patients and was not detected for non-smokers. Bioinformatics analysis showed that the spectrum of transcription factors binding with high-risk C allele differ from the spectrum of transcription factors specifically binding with the reference T allele; these factors are involved in the regulation of the biosynthesis of ketone bodies and cellular response to glucocorticoid hormones. The results suggest that smoking plays a trigger role in the relationship of the polymorphic variant rs11927381 of the IGF2BP2 gene with the development of type 2 diabetes mellitus.
