Chemerin rs17173608 Gene Polymorphism is not Associated with Type 2 Diabetes Mellitus: a Cross-sectional Study

Background: Previous studies have shown that chemerin has important roles in the development of obesity, insulin resistance, metabolic syndrome, polycystic ovary syndrome (PCOS) and T2DM. The main goal of our study was to investigate the role of Chemerin rs17173608 gene polymorphism in T2DM (type 2 diabetes mellitus). Materials and methods: 100 patients with T2DM and 50 healthy volunteers were included in the present study. DNA isolation from blood samples was performed with K1820-02 DNA Mini Kit. Chemerin gene polymorphism was detected by Tetra- Amplification Refractory mutation system polymerase chain reaction (T-ARMS-PCR). At the end of T-ARMS-PCR, samples were run using gel electrophoresis. Some samples were validated by sequence analysis. Results: In the genotype analysis, 18.0% of patients had TT genotype and 81.0% of TG genotype was detected. GG genotype was not detected in any patient. Genotype of 1 patient was unidentified. Genotype distribution of healthy control group was 12.0% TT genotype and 88.0% TG genotype. Similar to the T2DM group, the GG genotype was not detected in the control group. There was no statistically significant difference between T2DM group and healthy control group for TG and TT genotypes. Conclusion: To our knowledge, chemerin rs17173608 gene polymorphism has been investigated in T2DM for the first time herein. In the present study, the TT genotype ratios were higher in the T2DM subjects than in healthy subjects. G allele frequency in the T2DM group was lower than that in the control group. However, there was no statistically significant difference between the groups.
