Purpose
Mutation in various regions of the adiponectin (ADIPOQ) gene is described to be associated with type 2 diabetes (T2D). Our aim was to investigate the association between rs1501299 (SNP + 276 G > T) and rs266729 (SNP-11377 C > G) polymorphisms of ADIPOQ gene and susceptibility to T2D in an Iranian population.
Methods
This is a case-control study. A total of 210 subjects including 100 patients with T2D and 110 healthy controls were selected from an Iranian population. SNP-11377 C > G and SNP + 276 G > T polymorphisms were investigated using the Tetra ARMS-PCR method.
Results
The genotypes frequency of the SNP-11377 C > G polymorphism (P = 0.21) and SNP + 276 G > T polymorphism (P = 0.10) were in agreement with the Hardy-Weinberg equilibrium. The genotype and allele frequencies for rs266729 polymorphism showed a significant difference between the T2D and control groups. Further, the frequencies of the genotypes of GG (OR = 2.43, P = 0.031), GG + GG (OR = 2.11, P < 0.01) and G allele (OR = 1.6, P = 0.041) in SNP-11377 C > G polymorphism was significantly associated with an increased risk of T2D compared to control group. While, there was no significant association between the different genotypes of SNP + 276 G > T polymorphism and the risk of T2D in an Iranian population. The circulating adiponectin level in T2D subjects had significant difference compared to the control group in rs266729 polymorphism.
Conclusion
We concluded that ADIPOQ rs266729 (SNP-11377 C > G) gene polymorphism but no rs1501299 is associated with increased risk of T2D in our population.
