In the logistic regression analysis, SLC2A4 rs5435, rs222852, rs5418, and rs8082645; RBP4 rs3758539; PCK1 rs1042531, rs2236745, rs28359554, and rs707555; and PIK3R1 rs40419, rs1819987, rs34309, and rs6890176 were not associated with GDM, regardless of genotype and use of dominant model, recessive model, or additive model comparisons (Table S7). This evidence concerns the gene PIK3R1 and gestational diabetes.
