The PON1 -108C/T and 192Q/R variants, age, apoA1, apoB, and MDA were significant predictors of the PON1 levels, and the PON1 192Q/R variant, apoB, TAC, and MDA were significant predictors of the NLA in the women with and without GDM (Table 5). This evidence concerns the gene PON1 and gestational diabetes.
