Susceptibility, Genetic

This is a retrospective cohort study of patients with T2DM who were treated with exenatide twice daily as a part of their diabetes care for at least 12 months. The objective of this study is to investigate the influence of T2DM susceptibility gene polymorphisms (NOS1AP, KCNQ1, TCF7L2, WSF1, GLP-1R, etc.) on the efficacy of GLP-1 RA (exenatide, liraglutide, etc.), to identify the variables that can predict the efficacy of GLP-1 RA, and to evaluate the weight of these variables on the efficacy.

In this study, investigators wanted to determine the effect of T2DM susceptibility gene mutations on self-expression. Participants (T2DM patients and controls) were recruited to identify genotypes and detect the levels of T2DM susceptibility genes expression in the fresh peripheral plasma. The normal pancreatic tissues or adjacent tissues of pancreatic cancer were also collected to identify the expression differences of T2DM susceptibility genes under different genotypes.
