Association analysis of SLC30A8 rs13266634 and rs16889462 polymorphisms with type 2 diabetes mellitus and repaglinide response in Chinese patients.

Objective: Genome-wide association studies (GWASs) identified that SLC30A8 genetic polymorphism was a risk of type 2 diabetes mellitus (T2DM) in several populations. This study aimed to investigate whether the SLC30A8 rs13266634 and rs16889462 polymorphisms were associated with T2DM susceptibility and repaglinide therapeutic efficacy in Chinese T2DM patients.

Methods: We conducted a case-control study of 443 T2DM patients and 229 healthy volunteers to identify SLC30A8 rs13266634 and rs16889462 genotypes by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay.
