Gestational diabetes mellitus (GDM) is defined as hyperglycemia detected during pregnancy and its risk is increased with obesity. Chemerin, an adipokine, has been proposed as potential mediators of insulin resistance in GDM. This case-control study was designed to assess the relation between chemerin SNPs rs4721 (or rs10278590) and rs17173608 and the development of GDM. One hundred thirty GDM pregnant women with GDM and 160 healthy pregnant women were enrolled in this study. The diagnosis of GDM was based on the International Association of Diabetes and Pregnancy Study Group (IADPSG) criteria. Chemerin rs4721 polymorphism gene was amplified through PCR, and SNP was detected using restriction enzyme AluI. Genotyping for chemerin rs17173608 polymorphism was performed by using tetra-amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR). Blood glucose level was measured by an enzymatic method. Our finding showed that the genotypes frequency of chemerin rs4721 polymorphism was significantly different between GDM and non-GDM groups (χ = 7.44, P = 0.02). The genotype of rs4721 was significantly associated with GDM in co-dominant and dominant genotypes (GG vs GT, OR = 2.3, 95%CI = 1.24-4.24, P = 0.008, and GG vs GT + TT, OR = 2.21, 95%CI = 1.23-3.99, P = 0.008, respectively). No significant difference was observed in allele frequency between case and control groups (P = 0.62). Moreover, the genotypes and allele frequencies of chemerin rs17173608 polymorphism did not show significant differences between GDM and non-GDM (P > 0.05). We concluded that the genotype of rs4721 was found to contribute significant risk to GDM while genotype of rs17173608 could not predict the risk of GDM.
