Association between chemerin rs17173608 and vaspin rs2236242 gene polymorphisms and the metabolic syndrome, a preliminary report.

Metabolic syndrome (MeS) is associated with increased risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease. There is some evidence indicating that adipokines play a role in the development of MeS. The present study was aimed to investigate the impact of chemerin rs17173608 and vaspin rs2236242 gene polymorphisms with the risk of MeS in a sample of Iranian population. This case-control study was done on 151 subjects with MeS and 149 without MeS, as defined by NCEP-ATPIII. Tetra amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) was designed to detect the polymorphisms. Our finding showed that there are significant differences in genotype frequencies between the groups regarding vaspin rs2236242 polymorphism (χ(2)=18.74, p<0.0001). A significant protection against MeS was found for vaspin rs2236242 in allele and genotypes (Odd Ratio [OR]=0.52; 95% confidence interval [CI]=0.37-0.72; p=0.0001, T vs A; OR=0.49; 95%CI=0.29-0.82; p=0.007, TT vs TA and OR=0.17; 95%CI=0.07-0.40; p<0.0001, TT vs AA). Our finding showed positive association between chemerin rs17173608 polymorphism and risk of MeS (χ(2)=7.70, p=0.021). The G allele increased the risk of MeS (OR=1.78; 95% CI=1.14-2.78; p=0.012) as compared to the T allele. In conclusion, our data suggest for the first time a significant association between vaspin rs2236242 and chemerin rs17173608 polymorphisms and the MeS in Zahedan, southeast Iran. Further studies with large sample size and different ethnicities are required to confirm our findings.
