Aims

Recently a relationship between circadian clock function and the risk for type 2 diabetes (T2D) has been shown. BMAL1 is a key component of the mammalian molecular clock. Two SNPs in the BMAL1 gene have been identified to confer T2D susceptibility. In the present study we investigated for the first time the association between the BMAL1 gene and the risk for GDM, in a Greek population.

Methods

We studied 185 women with GDM and 161 non-diabetic controls for BMAL1 polymorphisms. For BMAL1 mRNA expression, peripheral leukocytes were harvested from 20 GDM and 20 control women, harboring different genotypes for the tested polymorphisms, using real-time quantitative PCR.

Results

The minor allele (A) of the BMAL1 rs7950226 (G>A) polymorphism was found to be significantly associated with an increased risk of GDM (P=0.025). Analysis of the second BMAL1 rs11022775 (T>C) polymorphism, showed that the C-allele frequency was strongly increased in women with GDM (P=4.455e-06). The CC genotype was also significantly overrepresented in GDM vs. controls (P=0.00001). Additionally, the rs7950226G/rs11022775C and rs7950226A/rs11022775C haplotypes were also found to be associated with increased susceptibility to GDM. Furthermore, the expression levels of BMAL1 mRNA were significantly lower in GDM patients than in controls.

Conclusion

These data suggest that the impairment of the BMAL1 clock gene expression is closely associated with GDM susceptibility."xsd:string
