IGF1 and hyperinsulinemic hypoglycemia, familial, 4: On gestational day 19, prior to the euthanasia of the pregnant dams, maternal body weight was recorded, and no significant differences were observed due to ethanol consumption between both WT and HZ groups; whereas the presence of partial IGF-1 deficiency (HZ-Control, 40.73 g ± 1.28) showed a reduction in maternal body weight compared to the WT-Control (52.05 g ± 1.21; p < 0.05) and the WT-Ethanol groups (51.73 g ± 5.82; p < 0.05) (Table 1).
