Background: The variants of transcription factor 7-like 2 (TCF7L2) gene have been shown to be associated with type 2 diabetes mellitus (T2DM) and its related complications. Objectives: We aimed to explore the possible association of rs7903146 (C/T) variant in TCF7L2 with the risk of T2DM in the North Indian population. Methods: The present case–control study included a total of 638 human subjects (318 T2DM subjects and 320 healthy controls). Various anthropometric, biochemical, and genetic parameters were studies in all the subjects. Genotyping of TCF7L2 gene was carried out using allele-specific polymerase chain reaction method. Results: The results of this study indicate significantly higher values of body mass index, waist circumference, waist-to-hip ratio, and body fat (%) in T2DM subjects than controls (p≤0.001). Dyslipidemia represented by higher levels of triglycerides and reduced values of high-density lipoprotein was more predominant in diabetic subjects compared to healthy subjects. The frequency of risk genotype (TT) frequency was significantly higher in T2DM subjects (16.4%) compared to controls (11.6%). The “T” allele was more dominant in diabetic subjects than controls. Logistic regression analysis of the data revealed a significant association of TT genotype with 2-fold (odds ratio with 95% of confidence interval; 2.09 [1.29–3.42] p=0.003) and CT genotype with 1.7-fold (1.73 [1.23–2.44] p=0.002) increased risk of developing T2DM. Conclusions: The present study demonstrated a significant association of rs7903146 (C/T) variant in TCF7L2 with the augmented risk of T2DM in North Indian population.

Family history has considered as a risk factor of type 2 diabetes. Transcription factor-7 like 2 (TCF7L2) hasrole to regulates insulin secretion and blood glucose homeostasis. The aim of current study was to determine thers7903146 polymorphism of TCF7L2 gene and homeostatic model assessment-β (HOMA-β) level on individual withand without type 2 Diabetes Mellitus (DM) family history. This work is a case-control study. Thirty six subjectswith type 2 DM family history and 36 subjects without type 2 DM family history were recruited. HOMA-βmeasure to analyze the insulin secretion. Polymorphisms of TCF7L2 gene was analyzed by using PCR-RFLPmethod. Statistical analysis was performed by using T-test, Mann-Whitney and Chi-square with signifi cancelevel 0.05. The frequency of the T allele of the cases were 4.2% and the controls were 2.8% (p=0.500). The oddratio was 0.649 (CI;95%:0.106-4.055). The HOMA-β levels of the cases were signifi cant low (132.56±62.48)compared with the controls (266.09±1.68) with p=0.000. The subjects with type 2 DM family history have asimilar frequency of having T alleles and CT/TT genotypes. The subjects with type 2 DM family history hassignifi cantly lower HOMA-β levels than subject without DM family history.

Background: Type 2 diabetes mellitus (T2DM) is the most prevalent component of metabolic syndrome. Environmental factors and various complex genes like transcription factor 7-like 2 (TCF7L2) gene have involved in the disease development. Objective: To determine TCF7L2 genetic association (rs7903146C/T and rs12255372G/T) in T2DM patients of Khyber Pakhtunkhwa population of Pakistan. Subjects and methods: This study comprised of 176 subjects including 118 T2DM patients and 58 healthy controls. Genomic DNA was extracted and genotype of common variants (rs7903146 C/T and rs12255372 G/T) was carried out by amplification-refractory mutation system (ARMS)-PCR of sequence specific oligonucleotides. Results: The distribution of genotype of TCF7L2 SNPs (rs7903146 C/T and rs12255372 G/T) was significantly associated with T2DM as compared to the controls (p <0.0001). The genetic models of the rs7903146 (C/T) and rs12255372 (G/T) SNPs were significantly associated between cases and controls (p <0.0001). On the other hand, the significant association was observed between the two SNPs and different biochemical parameters like serum fasting glucose, lipid profile, creatinine and blood HbA1c levels (p <0.05). Conclusion: It is concluded that the SNPs of the TCF7L2 gene are significantly associated with T2DM disease susceptibil- ity in the population of Khyber Pakhtunkhwa of Pakistan.
