Effect of Mutations in T2DM Susceptibility Genes on the Expression of Susceptibility Genes in Patients With T2DM and Controls

Summary

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.
