RS11212617 is associated with metformin treatment response in type 2 diabetes in Shanghai local Chinese population

ObjectiveThis study was designed to examine the relevance of single-nucleotide polymorphism (SNP) rs11212617 with treatment success in type 2 diabetes patients from Shanghai local Chinese Han population. MethodsWe genotyped rs11212617 in incident metformin users of type 2 diabetes patients from Shanghai local Chinese Han population. Association between rs11212617 and changes in HbA1c, fasting plasma glucose and postprandial glucose level were analysed. ResultsTwo hundred and seventy-four incident metformin users were included in the study sample. The SNP rs11212617 was significantly associated with metformin response in Shanghai local Chinese Han population. ConclusionThe rs11212617 is associated with a reduction in HbA1c, fasting plasma glucose and postprandial glucose level. These results suggest that metformin treatment may be more efficacious in Shanghai and valuable for Chinese daily clinical practice.
