As for the clinical parameters in the first trimester (shown in Table 2), GDM women had significantly higher glucose (4.87 vs. 4.64), TG (1.55 vs. 1.33) and ALT (18.00 vs. 14.30) levels, but a lower AST/ALT ratio (0.96 vs. 1.18) and HDL-C level (1.83 vs. 1.98). This evidence concerns the gene GPT and gestational diabetes.
