In addition, SLC30A8 rs2466293 was associated with increased GDM risk in the dominant model (GG+AG vs. AA: OR = 1.184; 95% CI: 1.013-1.383; P = 0.034), recessive model (GG vs. AG + AA : OR = 1.408; 95% CI: 1.135-1.747; P = 0.002), codominant homozygous model (GG vs. AA : OR = 1.474; 95% CI: 1.167-1.861; P = 0.001), and allele model (G vs. A: OR = 1.195; 95% CI: 1.069-1.336; P = 0.002), and no significant association was found in other genetic models (Figure 3). Here, SLC30A8 is linked to gestational diabetes.
