No changes in placental ASAH1 levels were observed with respect to fetal macrosomia (mean (SD) protein fold changes in CTR vs. T1DLGA: 1.00 (0.20 vs. 1.14 (0.45), p = 0.54; in T1D vs. T1DLGA: 1.41 (0.44) vs. 1.14 (0.45), p = 0.19; in CTR vs. T2DLGA: 1.00 (0.17) vs. 1.24 (0.41), p = 0.17; and in T2D vs. T2DLGA: 1.39 (0.37) vs. 1.24 (0.41), p = 0.55). This evidence concerns the gene ASAH1 and Large for gestational age.
