Correlation Between Gene Rs8192678 G>A Polymorphism and Susceptibility To Type-2 Diabetes.

OBJECTIVE

To systematically investigate the correlation between the G>A polymorphism of the peroxisome proliferator-activated receptor γ coactivator 1α () gene rs8192678 locus and the susceptibility to type-2 diabetes mellitus (T2DM).

METHODS

The inclusion and exclusion criteria and retrieval strategies of original literatures were formulated. Then, subjects and free words "PPARGC1A","gene polymorphism", and "T2DM" were retrieved from the PubMed, EMBASE, and Cochrane Library databases. Case-control studies on the G>A polymorphism of the gene rs8192678 locus and susceptibility to T2DM were included for the meta-analysis.

RESULTS

The number of cases in the T2DM group and control group was 5,607 and 7,596, respectively. The meta-analysis revealed that the gene rs8192678 locus G>A polymorphism is associated with susceptibility to T2DM. There are differences in each group of genetic models, of which three groups of genetic models are highly significant. In the allele model, OR=1.249, 95% CI: 1.099-1.419, and =0.001. In the dominant inheritance model, OR=1.364, 95% CI: 1.152-1.614, and =0.000. In the additive inheritance model, OR=0.828, 95% CI: 0.726-0.945, and =0.005. And one group is significant, in the recessive inheritance model, OR=1.187, 95% CI: 1.021-1.381, and =0.026.

CONCLUSION

In Western Asian, South Asian, European and African populations, the A allele of the gene rs8192678 locus may be one of the risk factors for T2DM.
