Objective: WFS1 genes are highly expressed in pancreatic β-cell and potentially play a role in the DPP-4 inhibitor treatment response in type 2 diabetes. The objective of this study was to investigate the association of WFS1 genes with the DPP-4 inhibitor treatment response. Material & Methods: WFS1 genes (rs734312 and rs10010131) were genotyped in a case control study involving 662 type 2 diabetes (T2D) patients, using RT-PCR methods. Cases identified as DPP-4 inhibitor users (sitagliptin, vildagliptin or linagliptin). A1c was used to assess the treatment response of DPP-4 inhibitors. Haploview 4.2 was used in genotype and haplotype analysis. The associations of single nucleotide polymorphisms in WFS1 genes were determined using binary logistic regression analysis (SPSS 20.0, Chicago IL). Results: The results shown that the WFS1 rs734312 [p(HW)=0.3411] and WFS1 rs10010131 [p(HW)=0.8238] were consistent with the Hardy-Weinberg (HW) test. However, only WFS1 rs734312 (�?2=1.174, p=0.0496) was statistically significant, and it predicted approximately 2.2% variants (Nagelkerke r2 =0.022) in the DPP-4 inhibitors treatment response. The logistic regression model shown that the WFS1 rs734312 (genotype AG) was a significant predictor to the DPP-4 inhibitors treatment response [odds ratio (OR) 0.55; 95% confidence interval (CI) 0.37-0.84]. Conclusion: This concluded that WFS1 rs734312 is associated with the DPP-4 inhibitors treatment response in T2D.
